Below are some of the cases, where incautious use of DiskPart causes data loss or inaccessibility:

DiskPart converts a basic disk to a dynamic disk. Before using DiskPart, you must ensure that the disk must be empty or contains either primary partition or logical volume to avoid loss of data. Furthermore, the basic disks containing fault-tolerant disk driver (FtDisk), must be converted using Disk manager rather than DiskPart before upgrading, or else, these situations will lead to data loss.

If the hard disk has already been upgraded to dynamic disk, then usage of DiskPart command can damage the partition table leading to data loss and the need of partition recovery becomes inevitable.

DiskPart verifies the particular partition that is is capable of containing an operating system’s startup files. If you mistakenly mark a partition as active and it does not contain the operating system’s startup files, your computer won’t start leaving the data inaccessible.

On basic disks, the partitions are deleted  through focus. Thus incorrect choosing of partition focus and thereby deletion causes data loss. Partitions lost in this way can only be recovered using any good partition recovery software.

Be extremely careful while using the ‘Create Partition msr’ command by DiskPart as it creates  Microsoft reserved partitions as the first partition. However, GUID Partition Table (GPT) disks require a particular partition layout and creating Microsoft reserved partitions as the first partition could cause the disk to become unreadable resulting in data loss.

All these cases of data inaccessibility or loss necessitate partition recovery as those partitions contain your valuable data. Furthermore, in the above cases, when backup is not available or failed to restore the data due to any erroneous reason, use of partition recovery software to get back your data is the only option left.

These Partition Recovery tools are safe and are easy to use without the need of any prior technical knowledge. The application use a certain set of scanning algorithms which help extracting lost information.

Let’s take a real life scenario:
These days, tools are available for making partitions to your existing hard drive partition without even losing the stored data. Take a similar scenario that you tried some application to re-size your old hard drive partition and during the process, there is a sharp power outage. Your system gets shutdown and you get the unusual blue screen with a error message.
The Error message reads like:

“A problem has been detected and windows has been shut down to prevent damage to our computer”

Explanation:
The system becomes stops booting with the Blue Screen Of Death and the error message on the screen. Hence, all your data in the hard drive becomes inaccessible.

Cause:
This is an internal problem with Windows operating system that the partition gets corrupted if the partitioning process is being carried out by a third party tool and is interrupted in the middle.

Resolution:
Start your computer and press the F8 key to go to the Windows advanced menu.
When Windows advanced options menu appears, select Last Known Good Configuration (your most recent settings that worked), and then press ENTER.
Try to disable your anti-virus or backup utilities and then, boot from the install CD.
Use CHKDSK command to check and repair the hard drive corruption.

If the above measures fail to resolve the issue, you need recreate all the hard drive partitions by reformatting the system. Reformatting will erase all the data in the hard drive partitions and in such circumstances, you have to use any effective Partition Recovery application to recover and restore your lost data. Such Partition Recovery applications incorporate advanced and effective scanning algorithms with an interactive graphical user interface.

Stellar Phoenix Windows Data Recovery is one of the trust worthy Partition Recovery Software available in the market. This application supports Windows Vista, XP, 2003, 2000 and recovers your lost or inaccessible data form any hard drive make/model.

Let us discuss the scenario in a bit more detail. You have two partitions with two different OS installed into them. An error popped up and the booting process is halted. The error reads like:

“Could not read from the selected boot disk. Check boot path and disk hardware.”

Causes:

Foremost causes behind the above error message are:
boot.ini file is corrupt or missing or invalid.
Invalid partition path of Windows XP in boot.ini file
The Ntoskrnl.exe file is missing or damaged.

Resolution:

In order to resolve the above error and to access the data, following steps are to be followed:
Try running Windows Setup from the product CD shipped with your computer manufacturer.
Run “Recovery Console” by pressing ‘R’.
Choose the option to restore your system to previously saved configuration.

However, even after following the above measures you may not be able to recover Windows partition. Further you may encounter these following issues:

While running “Recovery Console”, a command prompt may come up without any login option.
While running the product CD, the installation can not be completed.
You may encounter an “Access Denied” error message while trying to access the Windows folder.

In the above scenario, to get rid of the error, you need to reinstall the operating system. As, a fresh installation of the operating system will delete all the data from the particular partition of the hard drive, you need to perform Partition Recovery. With a easy-to-use graphical use interface, Partition Recovery utilities have advanced and effective methods to completely recover and restore your data.

Stellar Phoenix Windows Data Recovery is one of the best buy Partition Recovery Softwares which provides a smooth recovery of all your lost data from the inaccessible partition. This Partition Recovery Software is a powerful recovery tool with complete compatibility to Windows XP, Vista, 2003 and 2000, supporting more than 300 file types.

The NTFS file system structure uses a number of system files, which are responsible for performing specific operations. Some of the major attributes of NTFS file system are as given below:

Multiple Data Streams- It supports various data streams, where stream name recognizes new data attributes on file. You can open a handle to every data stream.

Reparse Points- These are new objects of NTFS file system, which have definable attributes having user-controlled information and are employed for extending functionality in I/O (Input/Output) subsystem.

Change Journal- It is used by the NTFS file system to offer a pertinacious log of all the modifications made to Windows files on NTFS partition.

Sparse File- It enables Windows applications to create large files, however to use hard drive space only as required.

Data Encryption- It improves data security and prevents unauthorized access of your valuable data.

In some cases, the structure of NTFS file system corrupts and you come across error messages similar to the following ones while accessing the partition:

Event ID: 41
Source: Diskperf
Description: The file system structure on disk is corrupt and unreadable. Please run the chkdsk utility on the device with label “Volume_name”

Event ID: 55
Source: NTFS
Description: The file system structure on disk is corrupt and unusable. Please run the chkdsk utility on the volume “Drive_letter:”

In such cases, you need to format your hard drive and reinstall operating system to fix the file system problem. However, it removes all the disk partitions and causes further partition loss situations, raising the need of Windows partition recovery.

You can easily recover partition using commercial partition recovery software. They are capable of systematically scan the Windows hard drive using advanced scanning algorithms. The applications are pretty safe and easy to use.

Stellar Phoenix Windows Data Recovery software recovers lost, missing, deleted, and inaccessible Windows hard drive partitions. The software retrieves all exFAT, NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions. It is usable with Microsoft Windows 7, Vista, 2003, XP, and 2000.

Consider a scenario wherein you have a Windows 98 system that you have upgraded to Windows XP with FAT32 file system. However, when you start the system it fails to do so. An error message is displayed as a result, which is:

“NTLDR is missing

Press any key to restart”

Cause:

The root cause of this erroneous situation is that Windows 98 startup code ignores the BPB (BIOS Parameter Block) and starts the system even if the respective value is incorrect. However, this value is required in Windows XP, and thus, the system does not start if this value is incorrect.

Resolution:

To resolve this situation, you should correct the heads value in the FAT32 BPB to start Windows XP. To do this, perform the following steps:

• Restart the system using Windows 98 startup CD.
• Make a copy of the msdos.sys file by entering the following commands at the command prompt:

attrib -h -r -s c:\msdos.sys

rename msdos.sys *.ysy

• Type the following command in the command prompt to rewrite the startup code with the correct BPB information:

sys c:

• Start to the Recovery Console and run the fixboot command to rewrite the Windows XP system startup code.
• Restart the system. It should run fine now.

However, if you are still facing the similar problems during startup then you should use a third-party partition recovery software to recover partition. Such partition recovery tools are read-only in nature that do not overwrite the existing data while scanning.

Stellar Phoenix Windows Data Recovery is a Windows partition recovery software that enables you to recover Windows partition from inaccessible FAT, NTFS, or exFAT file systems. It is capable of recovering more than 185 different file types, which can be customized even further, from various storage media such as hard drives, external hard drives, pen drives, iPods, etc. In addition, this partition recovery utility enables you to restore deleted emails from MS Outlook and Outlook Express. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Major components of Windows operating system:

• Boot Loader- MS Windows consists of a boot loader, called Ntldr, to load operating system into main memory, while booting.
• MBR (Master Boot Record)- It is the first sector of a partitioned Windows hard drive, which is responsible for storing primary partition table, uniquely identifying storage media, and bootstrapping operating system.
• Boot partition- It is a hard drive partition, which stores all significant files and data structures of Windows operating system, which are required for the system to boot up.
• File system- It is a data structure or database, which is used by operating system to store, manage, and manipulate files on hard drive.

Causes of Windows operating system corruption:

• Virus infection- Viruses are malicious programs that may damage operating system and your hard drive structure. They causes severe partition loss situations and put you in need of NTFS data recovery.
• Improper system shutdown- Operating system may also get damaged if your system shuts down improperly because of power outage or system crash.
• Corrupt system files or data structures- If Windows boot loader, MBR, and other data structures get damaged, operating system may not function properly. It causes serious data loss situations.

When operating system corruption occurs, your computer can not boot up and you can not get into it. Hard drive partitions become inaccessible and partition loss situations take place. It requires NTFS partition recovery to be sorted out.

Recovery is best possible using powerful and advanced third party applications, known as NTFS data recovery software. The applications methodically scan entire hard drive and extract all inaccessible partitions from it.

Stellar Phoenix Windows Data Recovery is the most advanced and efficient tool to ensure absolute Windows data recovery in all scenarios. It recovers exFAT, NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000.

In a practical scenario, Chkdsk utility may quit without repairing the file system if you run it on a FAT32 file system partition with corrupt file system. Chkdsk reports the file system correctly, either as FAT32 or as RAW (depends upon the extent of damage). If you run chkdsk <drive name>: /f command on same Windows partition, you face the following error:

“The type of the file system is FAT32.
Volume Serial Number is C408-2213”

When you apply Chkdsk again without command-line switches, the volume is still reported as corrupt. If you apply chkdsk <volume name>: on corrupt FAT32 file system partition, you encounter the below error message:

“The type of the file system is FAT32.
Volume Serial Number is C408-2213

Errors found. CHKDSK cannot continue in read-only mode.”

After this behavior, the Windows partitions remain inaccessible. To recover partition in such cases, you need to identify the cause of this behavior and fix it.

Root of the problem:

The problem occurs due to the backup copy of boot sector that FAT32 file system preserves. But, Chkdsk.exe utility doesn’t try to use the backup copy unless primary boot sector physically exists in bad sector. Chkdsk.exe gets I/O while attempt to read Windows partition.

Resolution:

You can fix this behavior of Windows operating system by replacing the corrupt boot sector using Dskprobe.exe utility. It replaces the corrupt boot sector by backup copy. Primary boot sector is the first sector of logical drive. Backup copy of the boot sector is stored at 6^th sector of logical drive.

In case you fail to replace the corrupt boot sector, partition recovery software are required to scan the entire drive and extract lost partitions from it. The partition recovery tools come equipped with simple and self-descriptive graphical user interface to offer easy recovery of lost Windows partitions.

Stellar Phoenix Windows Data Recovery is the most excellent solution of effective handle all data loss situations. The software successfully recovers all NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions. It is usable with Microsoft Windows 7, Vista, 2003, XP, and 2000.

Consider a scenario wherein you are using a Windows XP system. When you start the system, it fails to boot. An error message is displayed as a result, that could be either of the following messages:

• Operating system not found.
• Missing operating system.

You, then, start the computer from the Recovery Console mode to fix the errors. However, here as well you get an error message, that is:

“Setup did not find any hard drives installed on your computer.”

Cause:

There could be various reasons for this strange behavior of your system. They are:

• The BIOS system is unable to detect the hard disk.
• The hard disk is damaged and, thus, inaccessible.
• The Sector 0 of the hard disk has a damaged master boot record. It is quite possible that it got damaged due to some third-party programs or disk corruption.
• An incompatible partition is marked as active.
• The partition having the MBR is not active.

Resolution:

To resolve this issue and recover partition, you should perform either of the following methods:

• Contact hardware manufacturer: Contact your hardware manufacturer for the hard disk repair. However, it may further damage the hard disk, which may even result in data loss of your hard disk
• Verify the BIOS settings: Check the BIOS settings of your system. Ensure that the settings are appropriate and the BIOS recognizes the hard disk.
• Use Recovery Console: Run the Recovery Console to execute the fixmbr command. This command will repair the MBR of the active partition. Restart the system, it should run fine now.

However, if you are still facing the same error messages then you should use a third-party partition recovery software to recover Windows partition. Such partition recovery tools are read-only in nature that do not overwrite the existing data while scanning the storage media.

Stellar Phoenix Windows Data Recovery software is a partition recovery software that recovers lost, formatted, or deleted data from inaccessible or corrupted file systems. It works well in FAT, NTFS, and exFAT file systems. This Windows partition recovery software is able to recover more than 185 different file types from various storage media. This partition recovery utility is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Consider a scenario wherein you start your Windows XP system, but unable to do so. An error message is displayed, that is:

“Winnt_root\System32\Hal.dll missing or corrupt:

Please re-install a copy of the above file.”

In addition, you may observe the following strange behavior as well:
When you try to repair the system using the Recovery Console, the command prompt may appear but without any option to guide you to perform Windows installation.
When you try to repair the installation using the Windows XP CD-ROM, the previous Windows installation is not detected. Because of which, you are unable to repair Windows.

Cause:
There could be the following reasons for this erroneous situation:
The default vale of the Boot.ini file is either missing or corrupt.
In the Boot.ini file, the location of the Windows XP is different than the actual location.
The Ntoskrnl.exe file is either corrupt or missing.
In the Boot.exe file, the partition parth is set incorrectly.
There is hardware failure that is causing this issue.

Resolution:
To resolve this problematic situation, you should perform either of the following methods:
You should edit the Boot.ini file. This would serve the following two purposes:
To restore or correct the default entry of the Boot.ini file.
To make sure that other entries in the Operating Systems section of the Boot.ini file reference to the proper locations.
In the Recovery Console, you should use Bootcfg utility. This utility will correct the Boot.ini file.
In the Recovery Console, you should run the chkdsk /r command. This command is used to repair errors, locate bad sectors, and recover readable information from the disk.

You would be able to boot your system using the aforementioned methods. However, if you are not able to access the system then you should use a third-party partition recovery software. Such partition recovery tools are able to recover partition using fast yet sophisticated scanning algorithms.
