OT: corrupted FATs on an external drive

[peter kostov]

Hi,

I have a Samsung mp3 player that doesn't want to format his drive.
When I run fsck on it I get:

# fsck.vfat -rtlV -v /dev/sdb1
dosfsck 2.11 (12 Mar 2005)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
Checking we can access the last sector of the filesystem
Boot sector contents:
System ID "MSDOS5.0"
Media byte 0xf8 (hard disk)
       512 bytes per logical sector
      4096 bytes per cluster
         1 reserved sector
First FAT starts at byte 512 (sector 1)
         2 FATs, 16 bit entries
    126464 bytes per FAT (= 247 sectors)
Root directory starts at byte 253440 (sector 495)
       512 root directory entries
Data area starts at byte 269824 (sector 527)
     63127 data clusters (258568192 bytes)
63 sectors/track, 255 heads
        50 hidden sectors
    505550 sectors total
Starting check/repair pass.
Both FATs appear to be corrupt. Giving up.

I have tried mkdosfs with no luck.
I will appreciate very much if anyone can tell mi what to do to get it 
back to work.
