Hard Drive Repartitioning Cause Partition Table Corruption and Partition Loss in Windows

Hard drive repartitioning is a common task that you need to perform either for better management of your data or to install an additional operating system on your Windows computer. If you have an unpartitioned hard drive, it becomes essential to create a new partition to install another operating system or make your system dual-boot. You can do it using Fdisk tool or Disk Administrator in Microsoft Windows. In some cases, hard drive repartitioning corrupts partition table and lead to serious partition loss situations. At this point, you need to opt for Windows Partition Recovery to retrieve lost partition and stored data.

Microsoft Windows Disk Administrator (and Fdisk engine that it shares with the Setup) writes Windows partition table information to hard drive based on the Cylinder-Head-Sector geometry of the hard drive. For SCSI (Small Computer Systems Interface) hard drives, this geometry is devised by drive, instead of being inherent property of hard drive. MS Windows follows a comparatively standard method for using geometry, which produces 1 MB tracks. However, SCSI hard drive that run with BIOS (Basic Input Output Systems) or other systems could use varying geometries.

Cause of the problem

When the hard drive with multiple volumes is taken from one computer to another, which uses different geometry, repartitioning the hard drive with Disk Administrator may cause Windows partition table to become damaged. This issue takes place because Windows Disk Administrator adjusts all the partitions on the track boundaries based upon current hard drive geometry. If partition table entries for existing partitions are rewritten with new starting offsets, data stored on those partitions becomes inaccessible.

Resolution

You can correct or avoid this issue by editing partition table to set partition length and start sector back to original value. You can determine disk geometry by using BPB (BIOS Parameter Block) in sector one of physical volume. You can also use sector zero of disk partitions that also has a BPB for finding starting sector offset.

If above method does not work, you need to format the hard drive and recreate partition table by reinstalling the operating system. Though, this method fixes all such issues, but also removes the hard drive partitions and need Partition Recovery to be handled.

You can perform quick and easy Windows Partition Recovery through third-party applications, known as Partition Recovery Software. The applications are pretty safe and easy to use with read-only conduct and rich graphical user interface.

Stellar Phoenix Windows Data Recovery is the most excellent solution to recover lost hard drive partitions. It works well with Microsoft Windows 7, Vista, 2003, XP, and 2000. The softwre recovers FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions.

File and partition Loss Due to File System Conflicts While Reinstalling Windows


In Microsoft Windows operating system, the hard drive formatting is the process of removing all of the hard drive partitions and stored files. This process is particularly carried out to remove errors from the hard drive or to prepare the hard drive for first time use. The formatting may also be performed when you reinstall or upgrade the operating system. Some nasty viruses or other malicious programs may also require hard drive formatting. Although, it corrects all of the hard drive errors, but also has a downside of file loss. In cases of loss of business critical files, you need to go for Partition Recovery solutions using appropriate tools.

Operating system corruption is the major cause why you require to format the hard drive. When a operating system corruption takes place, to correct it, you are required to reinstall the operating system. As mentioned above, the operating system reinstallation needs formatting of primary partition or the system partition. It would remove the files that are stored in My Documents, Shared Files and Desktop folders.

Under some circumstances, when you reinstall the operating system by formatting primary partition of hard drive, you might find that other hard drive partitions are not accessible. The logical partitions of hard drive gets damaged and the stored files become inaccessible. After completion of operating system reinstallation, when you attempt to access logical Windows hard drive partitions, the following error might occur:

“The disk is not formatted. Do you want to format it now?”

In order to retrieve lost or inaccessible files in such situations, you need to find out the cause of data loss and go for appropriate Partitio Recovery solutions.

Root of the issue

The major cause of this problem is caused by the file system corruption. When you reinstall the operating system, if the extended and primary partitions are using same file system, this kind of issues might occur.

In these cases, you need to format the entire hard disk and recreate all of the Windows partitions. It will remove all files from the hard drive partition. At this point, Partition Recovery Software come for your help.

These are advanced third party applications, which use advanced scanning mechanisms to retrieve all of the lost files from lost partition. The Partition Recovery Software are quite safe and easy to use.

Stellar Phoenix Windows Data Recovery is the most excellent solution to recover all sorts of lost files. This tool is capable of recovering files from FAT32, VFAT, NTFS and NTFS5 file system partitions. It is designed for Microsoft Windows 7 RC1, Vista, 2003, XP and 2000.

Partition Loss When Roxio GoBack Changes MBR and Partition Type

An operating system upgrade is performed to take benefits of added features and functions of the new versions. But sometimes after upgradation, your computer may not boot or the hard drive partitions go missing and your critical data becomes inaccessible. This behavior results as serious partition and data loss situations and require Partition Recovery tools for resolution.

As a practical scenario, when you attempt to upgrade to Microsoft Windows XP or when you attempt to install a new hard drive on your Microsoft Windows XP computer, the hard drive might not appear in My Computer or in Windows Explorer. The hard drive might appear in the Disk Management console and in Device Manager. In this case, the Disk Management console can not be used to assign a letter to the hard drive.

This behavior of Microsoft Windows XP may make your entire hard drive and all of its partitions inaccessible. Therefore, you can not access data and information from the hard drive partitions and come across partition loss situations. In such cases, to get your partitions and data back, you need to find out the cause of this problem and perform Partition Recovery as per the basis of data loss.

Grounds of this issue

This issue might occur if you have used Roxio GoBack tool on your hard drive. This problem takes place because the Roxio GoBack alters the MBR (Master Boot Record) of the hard drive and modifies the partition type. This behavior can cause the hard drive to be inaccessible in Windows XP, even when the hard drive appears in the Device Manager and in the Disk Management console.

  •   Roxio GoBack is a Windows based hard drive tool, which can record the disk changes. If the file system is idle for a while, it makes these changes as “safe points.” This tool allows the hard drive to be reverted to any point within the available history.

Resolution

You can sort out this problem by following these steps:

  Configure the hard drive as a primary master and then restart the system.
2   Disable Roxio GoBack.
3    Shutdown the system and then return the hard drive in its original configuration.
Although, this method may fix your problem, but it is not recommended to use it until you are not sure that you can safely follow all the steps. If this process fails, critical data loss may occur.

In such cases, you need to use partition recovery software that can systematically scan the entire hard drive and retrieve all lost partitions and data from them. These software are safe and user-friendly tools to perform absolute Partition Recovery.

Stellar Phoenix Windows Data Recovery is the most advanced and powerful partition recovery software. It supports FAT16, FAT32, VFAT, NTFS and NTFS5 file systems based partitions and volumes. The software is compatible with Microsoft Windows 7 (Currently in RC1), Vista, 2003, XP and 2000.

Rectifying Error Message “Non System Disk”

Partition Boot Sector is the first sector in the partition table that contains vital information used by file system to access the partition. The Master Boot Record (MBR) uses partition boot sector to load the operating system kernel files. Partition boot sector corruption may occur due to MBR damage, zeroing the partition boot sector, malicious software like virus etc. Once the partition boot sector gets corrupted or damaged, the hard drive partition becomes inaccessible. In such situations, you need to restore data from an updated backup. However, if you have not created any backup or it is not up-to-date, you should use advanced partition recovery software.

Consider a practical scenario, where you encounter the below error message when you attempt to boot from a partition:

“Non System Disk”

After the above error message appears, the partition becomes unmountable. In addition, you encounter the same error message each time you try to boot from the partition.

Cause:

The above error message mainly appears when the partition boot sector gets damaged or corrupted.

Resolution:

To resolve the above error message and boot from the partition, you should follow these steps:

•You can restore the backup of whole disk or MBR/Boot Sectors from the drive. NTFS (New Technology File System) maintains a duplicate copy of the boot sector, which is located on the disk.

•If a backup unavailable (in case of NTFS), you can try to locate a replacement of Partition Boot Sector.

•Furthermore, if the replacement boot sector is also unavailable, then only virtual partition recovery can be done.

However, if all the above measures fail to enable the system so that it can boot from the partition, the only option left is to go for a clean reinstall of the operating system. A clean reinstall erases all the data from the selected partition. In such data loss situations, you should use advanced Partition Recovery applications. Such recovery applications systematically recover and restore all the lost files and folders by using effective scanning methods. You can easily understand these tools with their user-friendly interface and no sound technical skills are required to use them.

Stellar Phoenix Windows Data Recovery is the most powerful partition recovery Software. It provides complete recovery and restoration of lost files and folders from lost, deleted, corrupted and formatted hard drive partitions and volumes. This read-only Partition Recovery tool is compatible with Windows Vista, XP, 2003 and 2000.

Error Message “No Bootable Partition” at Windows Startup

Division of a hard drive into various partitions enables you to install various operating systems in the hard drive. A hard drive partition can get corrupted due to various reasons such as operating system corruption, file system damage, Master Boot Record (MBR) corruption, malicious software like virus and more. Corruption of a hard disk partition results in an error message that does not allow you to boot the operating system. In addition to that, the error message makes the data saved on the hard drive partition inaccessible. For complete recovery of inaccessible data, you need to restore it from the latest backup. However, if you have not maintained any backup or the backup is not up-to-date, you need to recover and restore your precious data by using advanced Partition Recovery software.

Consider a practical example, where you receive the below error message when you attempt to boot your system:

“No bootable Partition”

You encounter the same error message each time you attempt to boot the system. Additionally, the data saved in the hard drive becomes inaccessible.

Cause:
The main reasons for the occurrence of the above error message are:

•The partition is not marked as Active.
•Physical cables attached to the hard drive are either not connected or are damaged.
•Corrupted MBR (Master Boot Record).
•Software bugs

Resolution:
To resolve the above error message and access the data saved in the hard drive partition, you need to follow these steps:

•Mark the hard drive partition as “Active”
•Check and reattach all the cables connected to the hard drive.
•Run FDISK /MBR from a bootable floppy to repair and restore the MBR.

However, if all the above steps fail to boot your system and you still encounter the same error message, you need to reinstall the operating system. A clean operating system reinstall erases all data from the selected hard drive partition. In such circumstances, you should use effective partition recovery software. Such partition recovery tools comprehensively recover and restore all the lost files and folders by employing powerful scanning algorithms. It becomes easy to apply these utilities as they have user-friendly interface. You can use them without any prior technical knowledge as they come with simple, easy-to-understand recovery screens with graphical documentation.

Stellar Phoenix Windows Data Recovery is the most feature-rich partition recovery software. It can easily recover data from lost, deleted, corrupted or formatted partitions and volumes. It is compatible with FAT16, FAT32, vFAT, NTFS and NTFS5 file system based windows partitions and volumes. It supports Windows Vista, XP, 2003 and 2000.

Volume Information Loss after Using Extend Partition

Windows Server 2003 supports clustering. The major benefit that user gets in clustered environment is failover support for back-end applications and services that are ought to have data integrity and high availability. Windows Server 2003 allows extending hard disk partition in clustered environment using DiskPart.exe. The Extend command can be used in DiskPart utility that enables a user to extend a partition. But in some cases, user finds situations in which volume information is lost and hence Partition Recovery becomes necessary as the solution.

•DiskPart.exe is a volume, partition and disk managing tool for MS Windows. The tool can take command-line parameters or scripts as input. The command is followed by the partition or volume that is selected and kept at focus.

This command line tool can only be used to extend the hard disk partition if system fulfills certain set of requirements. Among these requirements, availability of some additional free space at the end of the existing drive is most important. But there are several cases in which Partition Recovery requirements may arise when user finds volume information loss. When a user implements DiskPart utility in order to change hard disk partition size in clustered environment and then moves the volume, an error may appear as:

“The system cannot find the path specified.”

The error occurs when user attempts to view the contents of volume through command prompt after using DiskPart extend partition operation and moving the volume. However, a hotfix is available to correct the issue, but the information already lost is only recoverable using partition recovery software.

Partition Recovery applications are safe and powerful tools to extract lost, missing or damaged partition information. These tools use algorithms that scan the disk to restore the data. Partition Recovery Software provide interactive interface to offer complete user friendliness. In order to use these applications, it is essential to get a healthy bootable hard drive or a different computer to install the recovery software. The affected hard drive can then be attached to the bootable hard drive or the system to recover lost or corrupted partitions. If we install the application on the affected hard drive, it will overwrite the inaccessible files.

Stellar Phoenix Windows Data Recovery offers partition recovery using efficient scanning algorithms. This Partition Recovery Software is compatible with Windows Vista, XP, 2003 and 2000. It supports FAT16, FAT32, VFAT, NTFS and NTFS5 file systems based Windows partitions and volumes.

Erroneous DiskPart operation and Partition Recovery

Microsoft Windows offers a tool known as DiskPart that can be used to manage volumes, partitions and disks in a computer system. The tool accepts command-line commands as well as scripts as its input. In order to carry out any management task through the utility, we need to select the target object. The tool executes a given command on the object that has been selected like a partition or a volume of a hard drive.

 There are few cases in which incorrect use of DiskPart causes data loss:

 

  • If the hard disk has been upgraded to dynamic disk then use of DiskPart utility is not recommended to change disk structure. If it is used then partition table can get damaged. So instead Disk Management should be used. Partition Table is a 16-byte entry in MBR that keeps records of system’s partitions and hence its corruption will require partition recovery to extract data.

 

  • The incorrect use of DiskPart can corrupt partition table. On basic disks, the partitions are deleted with focus. Thus incorrect partition focus and deletion causes data loss. Partitions lost in this way can be recovered through partition recovery software. A user can use help command in DiskPart to know more about the available options. 

 

  • Unlike basic disks, deleting a single partition on a dynamic disk deletes all other offline dynamic volumes. Thus, we need to use ‘delete volume’ command.

 

 Partition Recovery

Lost, missing or damaged partitions need to be recovered as they contain valuable data. So, all users must take regular data backup. An updated and systematic backup can be used to restore precious data from the lost partitions.

 

When an updated data backup is not available and we need our critical files back, we should go for data recovery from the lost partitions. The productive tools that recover data in all cases of logical corruption can be used for recovery of lost partitions or volumes. These partition recovery utilities are high end applications that generally possess self descriptive interface. These applications incorporate advanced scanning algorithms and file signature information to recognize and extract lost files.

 

Stellar Phoenix Windows Data Recovery is the ultimate partition recovery software to recover lost, missing and damaged partitions. It offers extensive set of features incorporating effective scanning and safe data restoration. It supports FAT16, FAT32, VFAT, NTFS and NTFS5 file systems. It is compatible with Windows Vista, XP, 2003 and 2000.


False System Partition Issue and Recovery

Disks that contain dynamic partitions are called dynamic disks. These disks support multi-partition volumes and store partition information on the disk itself. LDM or Logical Disk Manager is the Windows subsystem, purposed for managing subsystem. It utilizes the information of LDM databases that hold partitioning information. Basically a dynamic disk is comprised of MBR, followed by LDM partition and LDM database.

Dynamic disks support various operations like creating or deleting mirrored, striped, simple, spanned or RAID-5 volumes, removing mirror and breaking mirrored volume into two and such others. But sometimes users report that when they view Disk Management Tool, two different volumes are seen enlisted as system partition, while the original dynamic system disk is visible as Offline or Missing. The attempts of deleting this fake system volume fail with the following error message:

“Cannot delete the system volume on this disk”

Also, user fails to reformat this partition, though it clicks Yes when the following error message pops up:

“This volume is no longer the current system volume. All data on this volume will be lost. Are you sure you want to format this volume?”

The root causes of this issue can be:

•    It may happen that user has manually broken system partition mirror and LDM private region database incorrectly shows the shadow drive as a system partition.
•    Two separate system volumes may also appear if previously system partition was mirrored to another dynamic disk in Windows 2000. Then if both halves became and mirrors failed, Windows 2000 was reinstalled. This resulted into a new system volume but with dynamic disk database having reference to the original system volume.
•    If this dynamic disk set has been imported into current system and has the flagged system partition in LDM, user may see two system volumes.

To correct this issue, we need to manually delete all the partitions and repartition the disk after backing up all the data of other volumes. Incomplete state of backup may create Partition Recovery needs. It can be accomplished using Recovery Console diskpart command. Though due to left information of dynamic disks in databases, dynamic system disk still appears with earlier issues, but it is of no harm.

Backup must always be checked and should contain all required files. However if backup fails, it requires Partition Recovery Software to scan and recover lost partitions’ information. These Partition Recovery applications are graphically rich tools that recover lost data in all logical partition loss cases. Partition Recovery Software are safe to be used.
Stellar Phoenix Windows Data Recovery is the best utility to safely carry out Partition Recovery. The application is interactive and has read-only design. It can thoroughly examine the drive for lost/missing/deleted partitions, recover and restore them. This Partition Recovery Software can be used with FAT16, FAT32, VFAT, NTFS and NTFS5 based disks. The software provides advanced recovery options. It can be used with Windows Vista, Server 2003, XP and 2000.

Which Partition Recovery Software in Case Of File System Corruption?

Which partition recovery software will fit your requirement? And will it really work, and work well? Well, firstly let’s scrutinize the last question here. We all be acquainted with how several government agencies can easily take whatever data they are looking for from any of the computer system, despite of whether the system was “purged of all the data”

Why is it so? It is because data and information is never actually completely erased from the computer hard drive! Anything “removed” is never actually lost, and is just residing there somewhere in your system, waiting to be recovered. You just need to consider which partition recovery software to use for effectively recovering the lost partitions and data from them.

Which partition recovery software is the best? If you have accidentally deleted your hard drive partition(s) or it has got deleted due to virus attack, most of the data recovery software can do it. However, if you hard drive partitions are invisible and inaccessible due to file system corruption, then only the great partition recovery software can do the job.

The file system corruption is the most severe case of data loss and could be handled with the most influential partition recovery software as the everything has got massed up. There is no file system table or any other data structure present on your hard drive.

In case of file system corruption, the partition recovery software having RAW File Recovery feature is required. Such software perform RAW recovery of the files, without taking any regard from the file system table and any other data structure.

There are some partition recovery software applications out there which can tackle with file system corruption as well, and with the minimum of bother. When you search for a partition recovery software, find one that could handle such situations and you’re pretty much set for every situation.

You should always bear in mind that data recovery software are different for every computer operating system and its file system(s). You must select one which is supportive to the combination of the same.

Stellar Information Systems Ltd is the most trustworthy and the advanced provider of data recovery software solutions. All of the partition recovery software of the company are highly developed and the most influential, able to handle all of the data loss cases.

Stellar’s partition recovery software have RAW File Recovery feature to perform partition recovery even in case of file system corruption. These software are powerful enough to perform thorough scan of the affected hard drive and carry out successful partition recovery.

File System Corruption after Using FDISK

Sometimes all of your hard drive partitions and data become inaccessible after using FDISK on your Windows file system. Some users think that these files and lost partitions could not be recovered by any means, but they are wrong. Your data is completely safe and recoverable using the partition recovery software.

The partition recovery software have been developed for retrieving data from the problematic hard drive and placing it on new storage media. The setup of such kind of recovery is at best tedious and in a few cases could make the current file system issue worse.

You should always bear in mind that not all data recovery software can perform partition recovery and hard drive recovery in cases of file system corruption. Only the best and the most influential hard drive recovery software, having RAW File Recovery option could do it.

The partition recovery software must be easy to use as it is not necessary that not all users, purchasing hard drive recovery software, are technicians. The data recovery software should be simple enough to perform Do It Yourself partition recovery.

The support to the file system and operating system combination of the hard drive recovery software is also an important concern. In this particular case, you need to purchase a partition recovery software which could recover data from Windows based computers, having the hard drive partitioned using FAT and NTFS file system.

Along with the software’s features, there are some general procedures which should be followed by the data loss victims, in order to minimize the severity of data loss and ensure the complete data retrieval.

You should never save and delete anything from the affected computer system as it could overwrite the data and can make it irretrievable forever. The data recovery software should always be installed on a healthy system and the pretentious hard drive should be attached to the same.

Stellar Phoenix Windows Data Recovery is the best partition recovery software of the data recovery industry and is capable of recovering data in all data loss posers. This hard drive recovery software is able to recover lost data from FAT and NTFS file system based Windows hard drives.

What makes this software great is the fact that it can fix all of the file system issues and can recover data from the inaccessible hard drive partitions.
