My laptop HDD recently would not load windows. So i installed the OS on a different drive. Now, when i connect the old drive VIA USB 2.0toSATA it will not show up in My Computer. Disk Management will not show the drive either. The HDD is getting power, i can hear the disk spinning.
Plug in and turn on the external USB hard drive
Right mouse click on My Computer
Left click on Manage
Left click on Device Manager
Expand the USB list
Find the USB device for your USB Hard Drive (the one that has no description)
Right mouse click - Uninstall
Turn off the external USB hard drive
Turn on the external USB hard drive and let it find and install the driver
Open 'Administration Tools', select 'Computer Management', click on 'Disk Management' and see if it can be seen here. If it does show here, chances are it doesn't have a drive letter assigned. If this is the case, right click on the drive, select "Change drive Letter...', and assign a drive letter to it.
If it was not seen there, go to 'Action' on the menu bar, click on 'Rescan Disks' and it should come up. If necessary assign a drive letter to as described above.
