Thankfully, this computer is used primarily for multimedia and any really important files are also backed up on my netbook. The keyboard on the lappy is dire, so it can't be my main machine which is a shame as it's a very powerful system despite being several years old.
The drive in question is my data drive - formatted ntfs for first Vista (bleck) and Win7RC, which I really liked. The only time I ever had a disk issue before this was after sending the machine to Sony for some servicing with the OS drive, and when it came back they hadn't 'added' my data drive so I had to hoke in Vista's Disk Management Console to get it back, which was easy enough.
As I said above, I was able to get the drive back and remount it with no issues, but I'm having no luck with the fstab. The drive comes back ok after sleep, so I suppose one option is to simply never shut it down, but I hate to waste the power!
And now I'm having wireless issues, but I think that's hardware - I was having occasional lapses in Windows as well. The on/off switch for the card doesn't always work. On the up side, my mobile broadband dongle works beautifully.
I'll post the edited version of fstab. Clearly I haven't added something vital!
# /etc/fstab: static file system information.
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
# <file system> <mount point> <type> <options> <dump> <pass>

I got the uuid for the drive ok and put in the filesystem type, but it doesn't work - I still need to manually remount the drive after boot.
