Another External H Drive is Not Accessible After Upgrading to Win 7

I have just upgraded to Win 7 and want to use old hard drive (Seagate 500 gb) as external usb drive. Other drives work just fine in the caddy.


However, when I connect this Seagate drive it does not show up in disk management. In device management it does show as USB Mass Storage Device.


I've tried 'uninstalling devices' - it gets stuck and won't complete. Any ideas?

Can you see it in BIOS? Does it have a drive letter?

Nothing in disk management. How do I check BIOS?

Thanks.

You might try another inexpensive SATA/IDE adapter, just in case there's a particular incompatibility with the one you're currently using and that old Seagate drive.

Don't know if the adapter I pointed to is available over there, but risking $15 or so in a new adapter to find out if it's your current adapter which is at fault, or maybe that old Seagate drive had simply died... well it seems worth the small cost.

Incidentally, there's actually another active thread right now also dealing with a Seagate 500GB drive and problems seeing it. Has your drive always been used for Windows only, or was it used for a Mac?

Another idea... just to experiment a bit... you can use Partition Wizard (and its standalone boot CD) just to see if that drive-in-adapter can be seen by something other than Windows.

No, it's always been windows. Thanks for the tip about Partition Wizard - but nothing showed.
