No errors messages at all, just *really slow*. Sounds like a bad disk to me. Run some diagnostic with smartctl (from the smartmontools package). What does 'smartctl -H /dev/sda' return ? (replace sda by your disk name if it's different). What's the content of the error log ? (smartctl -l error /dev/sda) A non-empty error log is a good sign the disk is on the down curve. Next, run a quick self test (smartctl -t short /dev/sda), wait 2 minutes then check the result with "smartctl -l selftest". If that succeeds, run a long test (smart -t long /dev/sda), which takes about 2 hours. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
