First and foremost, double check that your SATA cables are properly secure.
Install smartctl and run smartctl -a /dev/$disk0 (where $disk0 is e.g. sda); check to see if any of the various SMART attributes indicate a problem. Run a short, then a long SMART self test smartctl -t short /dev/$disk0 smartctl -t long /dev/$disk0 Note that long tests take a LONG time, and you might be best leaving it running and not using the disk much at the same time. It is an online test, but it can be noisy. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
