my exernal 300g usb2 hd drive is not being recognised by my vista laptop.

I keep getting the messgae usb not recognised message and it shows up in device manager and an unknow drive.


I had problems with it a few months ago after my pc froze while it was plugged in but I manged to reformat and recover all my software but I can't even reformat it without the drive being recognised.

I have lights and the unit is whirring ...has anyone got any ideas please

What happened when u plug the drive in few min. after start up?

Any action in the notification area or CPU activity?

And than the device manager?

Any exclamation marks in the dev. manager?

Rescan in the dev. manager for any hardware changes.
