Boot sector is the very first sector of a partition that conveys the required boot information to the system. FAT32 maintains the backup copy of the boot sector, usually at sector 6. Chkdsk can use this backup boot sector if you allow it to run while FAT32 volume corruption. But sometimes, the process fails and Chkdsk doesn't make any repairs for corrupted volumes. Thus, to restore lost information, you require using your recent data backup that should be valid and updated enough to give required data. However, if you face any issues with your backup, use data recovery services and applications as the solution to recover data.
As a practical example, when you observe a FAT32 volume as corrupted or inaccessible, you try to run Chkdsk to repair it. Chkdsk reports file system as FAT32 or RAW and it doesn't make any repairs and quits unexpectedly. You receive the similar message:
"The type of the file system is FAT32.
Volume Serial Number is C408-2213"
Subsequently, when you run Chkdsk without using any command-line switches, it again fails to repair corruption with an additional error message that it cannot continue in read-only mode.
Cause
By design, Chkdsk doesn't use backup boot sector to repair the damaged volume, unless it gets an I/O error message while accessing the volume. It happens if primary sector is physically located in a bad sector. Since the primary boot sector is corrupted or has invalid information, Chkdsk doesn't try to use the backup B.S and fails to repair volume corruption.
Solution
To repair the damaged volume when Chkdsk is failing to do so, you need to follow any of these methods:
Run Dskprobe.exe tool that could copy the backup boot sector and replace it over the damaged primary boot sector.
If the above measure fails or backup boot sector appears to be corrupted, reformat the damaged volume and restore from last backup. But if backup is damaged, not updated, or absent, scan your drive using Data Recovery Software. Such applications make safe Data Recovery using powerful and advanced scanning algorithms. Also, they offer graphically rich interface together with quality recovery options.
