FAT data recovery in case of MBR corruption

MS Windows has introduced a tool called DiskPart, which is used to manage partitions of a hard drive, volumes and disks in a computer system. It accepts command-line commands as well as scripts for its input. In addition to this, if you want to carry out any management task using this DiskPart utility, you need to select the target object first. Tool is devised to execute commands that have been given on the selected object such as partition or volume of a hard drive. However, one cannot deny from the possibility of DiskPart causing data loss due to incorrect utilization. Following are some of these situations:

  • If the hard disk has been upgraded to dynamic disk then use of DiskPart tool is actually not suggested to change the disk structure. However, if it is used, partition table may get damaged or corrupt. Here, rather using DiskPart the utilization of Disk Management is recommended. Partition Table is a 16-byte entry in MBR that comprises records of system’s partition and hence, corruption of any partition marks the need of a nice FAT data recovery tool to recover lost data.
  • Erroneous utilization of DiskPart utility can result in corrupt partition table. On basic disks, the partitions are deleted with focus. Therefore, incorrect partition focus and deletion of data result in data loss. The lost partition is recoverable using Partition Recovery Software. A user can use help command in DiskPart to get in-depth knowledge about the available options.
  • In contrast to basic disks, deleting a single partition on a dynamic disk will result in deletion of all other offline dynamic volumes. Therefore, we need to utilize ‘delete volume’ command.
Here, if a user commits a mistake of using Fixmbr on virus affected or hardware issue facing drive with no updated backup then the only way to retrieve your data is to perform FAT data recovery. FAT Data Recovery software offers interactive interface, read-only and sage scanning algorithms, secure data retrieval and other qualitative features to recover lost data.

However, in many other cases, where partitions are at the verge of data loss, partition recovery is the only tool that can rescue. FAT data recovery ensures the recovery of entire lost or corrupt partitions and then retrieval of vital data from them. This is the process where partition recovery software can help you. FAT data recovery software examines the hard drive for the lost or corrupt partitions with its unique in-depth scanning algorithms. This third party software ensures that the user does not lose on even a single bit of data. With an array of partition recovery features, the software comes along with few other features that help you recover data in different data loss situations.

Converting Dynamic Disk to Basic Disk to perform Windows Partition Recovery

When hard drive is partitioned in Microsoft Windows using the Master Boot Record (MBR) partitioning scheme, MBR Records store primary partition entries in the Partition Table. The number of partitions available on the Hard Drive does not matter as MBR can store descriptors for only 4 primary partitions. All extra Windows partitions created on the system are reckoned as the secondary partitions and their descriptors are stored in the linked list that starts from MBR. Unfortunately, in certain situations because of particular issues with this kind of partitioning scheme, all of the hard drive partitions might turn inaccessible and consequently you might lose the partition.

In order to sort out this issue, you need to perform windows partition recovery using appropriate recovery software. Dynamic disks in Microsoft Windows supports a very few of disk partition types some of which are OEM (Original Equipment Manufacturer) partition, type 0x42 partitions for dynamic disk and extended partitions. Additionally, when MBR is damaged, even the basic Windows disk might be reported as a corrupt dynamic disk. Such troubles usually arise in Microsoft Windows 2003 and 2000.

MBR might contain some invalid partition type because of wrong hard drive partitioning tool. In such cases, conversion of dynamic disk to basic disk gets failed. You can easily convert the disk by using Diskpart.exe. However, after rescanning it, hard drive again appears as Dynamic unreadable. However, make sure that the entire data in the drive is backed up before you decide to actually follow any disk conversion process. The process comprises of step that prompts you to remove data and therefore backup is always required. If you fail on creating a backup or if the backup gets corrupt, you would have to perform windows partition recovery.

When MBR or EBR gets damaged or face corruption, the presence of hexadecimal 0x42 values in any of them enables operating system to consider it as dynamic disk even if the disk is not dynamic.

To sort out this problem, you need to first ensure that this is the case of invalid system identification of system. If this is not the case, then the problem could be due to the damaged data structure that requires windows partition recovery tool to resolve the problem and recovery lost data.

Windows partition recovery software has been programmed to scan the affected hard drive and retrieve lost, missing and inaccessible hard drive partitions. This third party windows partition recovery software is totally safe and easy to use. Kernel for Windows Disk Recovery is a prominent software that professionally handles most of the partition loss situations. This tool is designed to recover FAT32 and NTFS file system partitions and is compatible with Windows 7, Windows Vista, Windows XP, Windows 2003, Windows 2000, Windows 98, Windows 95, and DOS operating systems.

NTFS data recovery when NTFS file system partition gets corrupt

Microsoft Windows operating system enables you to divide your hard disk drive into number of partitions for effective management of valuable data. Every Windows based computer has at least one system or boot partition that comprises of operating system for booting your computer. Rest of the partitions contain data and information. However, in case any of the partition corruption you might just lose important valuable data. This behavior results in severe data loss or partition loss and so will require NTFS data recovery, if you don’t have an updated or valid backup copy of the required data.

Any damaged boot or corrupt data partition that uses NTFS file system might show ‘stop 0X24’ error message while you access it. Hence, when you come across this error message while you reboot your computer or try to run the Windows Recovery Console, you might not be able to determine the root of this issue using general diagnostic steps. You might have to go with the method given below to perform NTFS Data Recovery:

1. Remove or turn the data disks off, which use the ntfs file system partitions

2. After identifying the issue with the disk, move your hard disk drive to another Microsoft Windows operating system based computer which is using a FAT32 or FAT 16 file system.

3. Utilize the ChkDsk /f utility to detect and fix file system related issues.

Utilize Windows operating system’s Recovery Console on Single Drive System:

If your system has only a single NTFS file system partition and no other Windows disks or computers are accessible, we suggest you to start your system from Setup disk to run Chkdsk utility and ntfs.sys driver disabled. Use the steps given below to repair NTFS file system partition and perform NTFS data recovery using the Recovery Console:

4. Start your system with the help of Windows 98 startup disk, insert Windows installation disk into the drive.

5. Change CD_ROM:\Support\Bootdisk folder, and run Makebt32.exe or Makeboot.exe for creating windows setup disks.

6. Alter Txtsetup.sif file with the help of notepad.

7. Start the affected system with the help of Setup.disk. Press F10 key on welcome screen to enter Recovery Console.

8. Run Chkdsk /p command to repair damaged partition.

9. Now quit the Recovery Console and reboot your computer system.

If the aforementioned method does not work, then use nice ntfs data recovery tool to recover corrupt or lost hard disk drive partitions. The application uses advanced scanning mechanisms to thoroughly scan the affected hard disk drive and extract all the deleted data from them. NTFS data recovery tool is designed to have user-friendly interface and so these utilities do not require any in-depth technical skills to perform ntfs data recovery. The NTFS data recovery tool can be installed on any version of Windows operating system to assist you retrieve the lost file and folders.
