My current Seagate Barracuda is slightly knackered (well, it has been since I had it, I just didn't notice, d'oh!) and I've had it over a year so it's out of warranty now.
I'm basically after a new one, it's for storage only (my Windows stuff is on the other hard drive, again a Seagate Barracuda which is fine) and the majority of stuff goes onto DVDs so I don't actually use it that much, only for storing things before I'm ready to put them onto the DVDs, however, if I can get one considerably bigger than 80GB (say, 160GB or even larger) for a fairly reasonably tempted then I may be swayed, so that I don't have to delete my anime and movies from there.
Sorry for making this such a long winded post when it didn't need to be. Basically, if the 160GB+ hard drives aren't much more expensive than the 80GB ones then I'll go for one of those :D
