I have the same problem. My PC, most of the time, will not recognize the external hard drive. The few times that it does, I have trouble ejecting it.
I too would appreciate any assistance.
I've been using a 300GB Maxtor OneTouch II for about two weeks now and I believe the Drive Lock feature is crashing my computer (running Windows XP Media Center Edition 2005).
When I boot my computer and turn the drive on, I get the window to enter the password to unlock the drive then a message saying I successfully unlocked it once I enter the password. However, my computer then completely freezes to the point I have to turn it off with the power button (instead of a proper shut down).
I haven't been able to find any information on anyone else having this problem. I've tried uninstalling and reinstalling the Dantz software and Maxtor drivers and utilities but still have the problem.
