Hmm, so far the only problem I have is finding enough stuff to make a dent in the capacity of that thing. I have about 200 books scanned in as PDF's and they don't even make it sigh.
Of course, I haven't gotten started on the aricraft, armor or personnel titles yet. Then there is the idea of copying my 25 gigabytes worth of music as a backup. It sure is a pain in the behind having to rip all those CDs when the primary hard drive takes a dump. Not to mention I can't plug my Zune back into the 'puter until they are all in otherwise the Zune will delete what it can't find as not being legit. Gotta luv DRM.
If you have any concerns about it, add a protection plan through Tiger Direct, I have done so with a couple of RAM sticks and they honored it in jig time with no questions asked.
For my primary back ups, I scored a nice 250 Gb Ferrari external Hard Drive that I refresh once a week, dumping the old back up in the process. It sure beats the heck out of paying some service online annually to do it for you. Having two places to have your stuff besides the primary is a great way to beat a malfunction in any one.
