About this tag
The automatic assignment tag covers issues where Windows fails to assign drive letters to newly connected storage devices, such as USB hard drives or adapters. Users report that drives appear in Disk Management but lack a drive letter, requiring manual assignment. Common troubleshooting includes checking the registry under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices for conflicts or corruption, and ensuring the system has not exhausted available drive letters. This tag is relevant for Windows 7 and later versions where automatic drive letter assignment stops working, often after frequent device connections or system updates.
