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.

If the mp3 player isn't working at all, try to check and see if you can change the drive partition(s). Doing this may fix the problem.
Also check to see if there is new software for the mp3 player as this could fix the problem.

What kind of error did you get with mkdosfs? Did you remember to specify that you wanted a FAT32 file system? (-F 32).

Thanks Mikkel, but there wasn't an error. There wasn't any effect also. I have tried several times with -F 16, because fsck reported: First FAT starts at byte 512 (sector 1) 2 FATs, 16 bit entries Then I have tried with -F 32, again with no success. As I sad mkdosfs didn't report any error, however in dmesg I saw several resets of the device during the mkdosfs process. After that when I remount the player all the files are still there, and the player itself again doesn't see them. Peter

It almost looks like the device is write-protecting its file system. But it could be from other causes. A couple of things to keep in mind. You should not run mkdosfs with the drive mounted. From the dosfsck output, the system thinks it is a FAT32 file system. You may want to run "fdisk -l /dev/sdb" to double check the partition type.
Dumb question - are you running mkdosfs on /dev/sdb1, and not /dev/sdb? Running it on /dev/sdb will produce strange results, including possible corruption of files on the device, possibly without messing up the directories...

I think the cause was the corrupted partition table ( from the mkdosfs output: 'Both FATs appear to be corrupt. Giving up.' ) I found a program called "YP-ST5 Updater" (windows executable from Samsung) that has overwritten the whole operating system of the player and the bootloader, firmware, etc. It has re-formated the filesystem, restored the FATs and now the player works fine.
P.S. the filesystem was not mounted and I have used mkdosfs on /dev/sdb1.
Thanks for helping anyway!
Best regards, Peter

Thanks for helping Robin. Your idea for updating the software has led me on the right way.
