Alright, so my Windows 7 recently quit assigning drive letters automatically. I frequently plug in new hard drives to the system using various USB to IDE or SATA adapters and now when I plug in a new hard drive with any of these USB adapters, it does not get a drive letter assigned to the volumes on the drive. If I go to Disk Management, the drives show up, and so do their partitions, and I can manually assign a drive letter to it, but this gets rather tedious. Any idea why it quit doing it automatically and how to get it to automatically assign drive letters once again?? I figured maybe it ran out of letters, so I went in the registry to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices and deleted all the remembered drive letter assignments in there, but that didn't help any. Any clues???
