Errors in Fat file system and recovery

FAT (File Allocation Table) is the computer file system structural design that is used by many operating systems including Windows. Basically, it is a table maintained on a hard disk to map data clusters. FAT is available in different variants, like FAT16, FAT32, VFAT etc. But sometimes, you observe that your FAT based hard drive shows expected behavior and as a result, system fails to boot. The reason could be file system corruption, which requires disk formatting as the solution. To restore data in such situations, you require using your recent data backup. However, if you face issues like, backup damage, incompleteness, or you don’t have any data backup, data recovery solutions prove as valid tools to recover all lost information from disk.

Consider a practical scenario, you start your Windows- based system that is using a FAT hard drive, it fails to boot and you receive the below error message:

“STOP: 0x00000023 (0xParameter1, 0xParameter2, 0xParameter3, 0xParameter4) FAT_FILE_SYSTEM”

Cause

Possible causes of the above error are enlisted below:

• Damaged device drivers
• Nonpaged pool memory depletion
• Low nonpaged pool memory resources
• Hard disk bad sectors
• File system corruption

Solution

To solve this issue, you need to carry out these methods:

• Download and replace device drivers on your hard drive.
• If nonpaged pool memory depletion is the issue, try restating the system. If problem persists, upgrade your system’s RAM.
• If your hard drive is suffering from physical bad sectors, you should backup all the data and replace the hard drive. In case of logical bad sectors, reformat the hard drive and restore data from backup.
• To correct file system errors, you need to run CHKDSK. It is a command-line tool that can fix most of the file system errors. If the same issue continues, reformat your hard drive and use your recent data backup to restore.

If due to any reasons, you find that data backup is damaged, not up to date or doesn’t exist, you require scanning your hard drive using data recovery software. These are powerful data recovery applications that employ safe algorithms to extract data from logically crashed drives.
