the last N sectors from the allocation strategy?
Can't you mark that clusters as bad with a diskeditor?
Can you suggest one that works on Linux?
Or which bits should I change if I use LDE?
(lde.sourceforge.net)

Try mbadblocks, part of the Mtools package (http://mtools.linux.lu/).
If it doesn't help, and you are brave, you may want to play with
mdoctorfat, which comes with Mtools, too, but is hidden for some reason. :->

Thanks. I have set up my /root/.mtoolsrc and:

# mbadblocks x:
plain_io: Input/output error
Bad cluster 63985 found
plain_io: Input/output error
Bad cluster 63986 found
plain_io: Input/output error
Bad cluster 63987 found
plain_io: Input/output error
Bad cluster 63988 found
plain_io: Input/output error
Bad cluster 63989 found

After unplugging the device didn't reformat itself.
Filling the disk seems to be working. It gives me
"disk full" without any new "Buffer I/O error on device sdc1"
or FAT panic messages in the kernel logs.

Thanks and best regards,
Zoltán Böszörményi
