Just had a power failure and am just going through my 4 USB disks to remount them and found that 1 (the most important one) is coming back as 'doesn't contain a valid partition table'.
What can I do to try to repair the disk and hopefully retrieve the partition? Luckily, I do nightly backups. but would like to get what was there today if possible.
This is a Linux computer and I'm using ext3 partition type.
dmesg is giving me the following:
