I have a 13'' MBP with Snow Leopard. I was using a GDrive Slim with Time Machine to back up my laptop and now the hard drive has failed. I can still access all my old back ups but for whatever reason it will not make new back ups. I have been working on it for about 7 hours now and just can't figure it out so I'm just going to cut my losses. I'm looking for advice on the best external/portable hard drive to use with Time Machine. I know a Time Capsule is ideal but it's a bit out of my price range. I'm looking to spend anywhere from $100 to $200. Any suggestions would be greatly appreciated.
