For example another problem computer found a failing DVDRW drive and who knows why that caused boot problems when a not by Seagate was plugged in.
Another owner was running bit torrents on the drive and it would not shut down till the torrents were killed off.
Your post is too light but tell more.
I have a system with W7 Ultimate on 64. Before that I used XP SP2 64 and the Seagate Free Agent run smoothly. After changing to W7 64, first it didn't saw the Free Agent. After installing the software from the Seagate website it was ok meaning that i could see the hard drive and work on it. After a week or so I started to have problems with W7 not starting up. After not being able to reinstall the W7 OR the XP and trying different things...I manage to understand that after un-pluging the Free Agent I could re install the W7 and since then it keeps having these problems: Not shuting down unless I un-plug the Free Agent or not being able to start W7 unless the Free Agent is unplugged. The Seagate Manager says the hard drive is fine after testing it on several occasions...
P.S. the Free Agent is connected with USB 2.0.
So...if anyone can help me please....
