Just like it says. I got Vista Ultimate today, installed it, then went to install my Maxtor One Touch III USB 2.0 since all of the drivers for my hardware is on there. At first it didnt detect the drive, then I turned the drive off and back on, then it detected it. Windows installed the driver for the backup drive and I was good to go. I got to install one thing off of the drive, I had to reinstall my computer after that. When my computer came back on the dirve wouldnt connect again. I dont get it? Its like Vista has something that is blocking the hard drive. The maxtor program says their is no drive connected when their is. Thanks in advance.
