So after my prehistoric motherboard finally died, I bit the bullet and did a complete system overhaul, upgrading to my current listed specs in my profile along with a new Windows 7 Home Ultimate x64 install.

However, it has provided me with an unexpected issue. Windows no longer detects my Toshiba USB 3.0 external Hard drive. I know that the computer itself can detect it because my Asus Sabertooth Z77 motherboard's BIOS window lists it among the connected drives. However, despite the LED light on the drive itself coming on when I initially connect it, the light eventually goes off. It is not listed in the My Computer drive listing, nor is it detected within the Disk Management or Device Manager lists of devices or drives inside Windows and it worked perfectly on my old Windows OEM x32 OS with my old build.

Can anyone help? All of my precious work is located on there, including my major college assignments due next week and while I did do backups every several days, one of the assignments was hammered out in less than that in several all night sessions. Any help would be greatly appreciated. Thank you!

Have you installed USB3 drivers? Check the Device Manager and see if the USB3 device drivers are installed.

Addendum: Never mind folks. Sorry, it seems that my motherboard actually has two sets of USB drivers and I didn't see or install the second. It's working now. Thanks for the clue Kari. :3
