Recently while testing some old hard drives on my new machine I broke the SATA power connector to my primary drive, and since my large external drive was failing I decided to replace both with a
3T seagate drive. A few things here once I got the drive I realized I wasn't going to be able to install windows on the drive and boot off it if I wanted to utilize the entire space, this caused so problems so what I did was format the drive as GPT and moved files from the failing external drive and a few other things, while a friend of mine send me a used 160g drive to use as my bootable drive. So I got the new drive put it in, removing all the other drives at the same time, and Install windows Vista 64 on it, I update the OS and all that then I go back put my old drives back in this is three drives, my 160g broken old primary drive so I could copy some stuff off it, A 1T drive I had for games and stuff, and the new drive. The old drives showed up just fine no problems, the new drive however windows wants to format, and when I tried to access it, I get an I/O error, at this point I am stuck I have no idea what to do to move that drive to the new install, I have since pulled the 160g drive and replaced the broken drive since I need to access the data on the 3T drive. It seems weird that I cant access that drive since everything I read says Vista can read GPT nativly, I should point out the drive works fine on the old install. Not sure what else I should include for data but any help would be appriciated.
