I need advice on purchasing an external drive for back up purposes. I just got a 15" MBP 2.8 500GB after getting some great advice from the group. I currently have a WD My Book Studio 1TB, which I purchased after a WD drive appeared to loose my information. In addition, I had a lacie drive that died several years ago, so I am not so confident in the external drives, so I want a secondary drive for the extra security. I went to purchase the same WD drive I got a few months ago, but learned that it no longer is sold because the drives have been updated, and not for the better. Ideally I would love to get a small drive that is 1TB that I can keep in a safe box, in case of the unexpected. I haven't been able to find any smaller portable drives that are 1TB and the 1 WD I found seems to be a no no. Something stable and reliable would be great. I am planning to begin using TM for backups. Any advice would be greatly appreciated. Thanks!
