Force overwrite FAT32 boot sector

#1 Post by tap2k » 19 Sep 2012, 02:33

Hi All -

I have a 400GB FAT32 external disk w/ one partition.

It looks like the FAT32 boot sector has been corrupted. TestDisk finds only one partition of size 1GB.

I am trying to rebuild the boot sector using Advanced -> Boot.

The backup boot sector looks OK using Dump, but TestDisk doesnt provide the [Backup BS] option because the size of the partition is greater then the size of the 1 partition that it does find from the corrupted boot sector.

Is there a way to force TestDisk to overwrite the boot sector from the backup?

See screenshot attached. (Ignore the size - Im working w/ a copy I made to a 1TB disk using dd)
