Windows 7 x64 Quit Assigning Drive Letters Automatically... ??

[thepunkerguy]

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???

Must go into disk management and initialize the drive.

Thats not the problem. All the drives I plug in have already been initialized on other systems and currently have valid windows partitions on them with data. If I simply right click on the partition in Disk Management and choose "Change drive letter" and then manually assign the drive a letter it works fine.. but this is a huge hassle as I plug in several different drives a day. Windows should, and always has just automatically assigned a drive letter to all valid partitions upon the drive being plugged into the system. Now it does not, something is wrong.

I had this problem too. The following solved it for me.

Open up a command prompt.
Type the following:
diskpart <enter>
automount enable <enter>

Good luck.

I've been struggling with this same problem (RAID1 which I have to manually assign a drive letter to each and every time I reboot; Win7 Pro 64bit)

I typed the following above and didn't have any luck. I'm wondering if it really pertains to what I'm trying to do.

My RAID1 is always connected and I never plan on disconnecting it. Its (2) SATA drives running as a RAID1.

Any other suggestions?

TIA

Been a few days... Anyone have any suggestions? Maybe I should create a new thread that is more specific?

this works but you have to do it from an evelated command prompt

Which is considered to be done by running it as an administrator right? (right click > run as an administrator)

I thought if it required elevation, it would prompted me to do so? I don't remember it ever prompting me to do so?
