So here's the deal. My friend and I ordered the Momentus XT from macsales.com. I was able to successfully upgrade my friend's hard drive and he's lovin' every minute of it. As for me and my experience with my own hard drive... not so much. I tried doing the same thing I did for him by using disk utility on Mac OS X 10.6.6 and just create a copy of my old hard drive. I get through the initial phase of it actually creating a copy and then it just fails on me. It comes up with a message stating something about an "input/output error". I've tried it a few times. I've erased the hard drive at least twice. I've verified and repaired the disk. I think I've tried everything but I'm still not getting any results. So if anyone can help me please do. I'm actually deployed right now and it'll be a pain in the _ _ _ to get a new one sent since it takes forever! Thanks!
