So you actually have five bad spots, two or three sectors apiece. dd if=/dev/zero bs=1024 count=12 seek=1073006628 of=/dev/sdc1 dd if=/dev/zero bs=1024 count=12 seek=1073101016 of=/dev/sdc1 dd if=/dev/zero bs=1024 count=8 seek=1335739456 of=/dev/sdc1 dd if=/dev/zero bs=1024 count=8 seek=1346771164 of=/dev/sdc1 dd if=/dev/zero bs=1024 count=8 seek=1348581732 of=/dev/sdc1 One last check: Did you run "badblocks /dev/sdc" or "badblocks /dev/sdc1" ?
