If so, look up GPARTED to delete the partitions on that drive and leave it blank. Boot into windows and head to the disk management to make a partition and format it. Sorry but GPARTED use, creation and more is on the web and it's free. Not too hard to use.
The hard drive is a Barracuda (80gb.) and I went to the control panel-->administative tools to intialize the drive and I get a error message "Drive not ready", what does that mean ? The drive was in a Playstation 2 and might have data on it. Another thing it's connected to the computer threw USB (it didn't matter before). All in all the drive is on,I can hear the motor, Vista is just not recgonizing it.I hope it's not a compatability issue.
