The hard drive that I store all my photos on is starting to play up. I can't open a couple of dozen photos, but luckily most of them are backed up in various locations.
The problem now is finding out where the dodgy files are and replacing them either from the backup drive (that I haven't used as often as I should), Deb's laptop (that only has backups of more recent stuff), the portable hard drive that we used in Vietnam (that was going to be used as a proper backup drive from today) or my backup at work (which was current as of around this time last year).
This year, the plan is to build a proper RAID file server so I won't have to worry as much about failing hard drives. Of course, I also need to figure out what the hell RAID really is, but that's a small detail.
