External HDD

Anyone has an idea, why it can't recognise my external hdd (WD2500JB)? I plug it in, I hear the sound, and then nothing. It's trying to install a driver, but it fails. Then it will show in the device manager, as "USB Mass Storage Device" In the safely remove wizard it's an unrecognised USB device.

I have a Gericom Supersonic PCI-E first edition laptop.
Mobile Intel® 915GM Chipset
1,73 GHZ CPU
Geforce Go 6600
1GB ram

I have a dual-boot system, and everything works fine in Vista, so my HDD and my USB slots ar fine. Pendrives, mp3 players also doesn't work. Any idea?

I had the same problem, i think it has somthing to do with Permissions, but not sure how to go about getting it to work

If you do this tutorial:-http://www.sevenforums.com/tutorials/507-built-administrator-account-enable-disable.html

and use the admin account it does let you access them, so it can be done!

Maybe someone knows how to access them with a normal account??

My normal account has administrator rights too, but I'll try this anyway, if there's the slightest chance. I tried everything else. New chipset drivers from intel, changing the power settings (regarding USB), safe mode...
So thanks for the tip.

Update: Didn't work. I'm starting to give up...
