Is your FAT32-based system is has become inaccessible lately? Are you unable to run chkdsk command to repair the boot sector? If your answers are in YES, then chances are that the file system has corrupted and you need to look for FAT recovery options. For this, you can use the in-built Dskprobe tool to repair the corrupted boot sector. If you are not able to recover the FAT system, then you should use a third-party FAT data recovery software to do the needful.
Consider a scenario wherein you are using Windows 2000 having FAT32 partitions on two volumes. One of its volume (not the system drive) gets corrupt and you attempt to run chkdsk on that volume using command-line arguments. However, the tool quits without performing any repairs. An error message is displayed, that is:
“The type of the file system is FAT32.
Volume Serial Number is C408-2213
Errors found. CHKDSK cannot continue in read-only mode.”
Such unusual behavior has occurred as the FAT32 partition stores a backup copy of the boot sector. The chkdsk command causes the error message while trying to read the corrupted volume. It does not uses the backup FAT32 boot sector until it is not physically located in a bad sector.
To recover the corrupted primary boot sector, you should use Dskprobe tool. To do this, you should perform the following steps:
- Find and run the Dskprobe.exe tool in the Windows 2000 installation CD-ROM.
- Click Logical Drive in the Drives menu, and then double-click DriveLetter.
- Clear the selected Read-only check box, click set active, and click OK.
- Click Read in the Sectors menu, and modify the default Starting sector (except the Number of Sectors=1 value).
- Click Write in the Sectors menu.
- While ensuring that the active handle is the logical drive letter of the volume, modify the starting Sector to write the data value.
- Click Write it, and click Yes to confirm that you want to overwrite sector 0 in the DriveLetter device.
- Exit Dskprobe.exe.
- Run chkdsk again for the repaired volume using the chkdsk DriveLetter: command. It should run fine now.
However, if you are still facing the similar symptoms while accessing that FAT32 volume then you should use a third-party FAT data recovery software. Such FAT recovery tools are able to restore trapped data from various storage devices using fast yet sophisticated scanning algorithms.
FAT data recovery software that recovers deleted, formatted, or lost data from corrupt or inaccessible FAT partitions. It performs FAT recovery for FAT12, FAT16, FAT32 and VFAT file system partitions. This FAT data recovery utility is able to recover more than 185 different file types from various storage media. In addition, this FAT recovery tool monitors the hard drive status and informs about the SMART attributes. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.
