Drive letters not assigning to DVDROM or external drives on notebook

I have an ASUS K52Jc running Windows 7 Pro 64bit. My DVDROM and external drives don't show up in My Computer, but are visible in Disk Management with no drive letter assigned. When I manually assign a drive letter it shows up for a second then disappears. Have also tried to assign a drive letter using DISKPART rom the cmd line to no avail. Does anyone have any ideas ?

Hi,

Try inserting a CD/DVD into the drive? Does it show up with a drive letter now?

Regards,

Hi hillsdave,

Try this.

Download v 0.8.1 of the drivecleanup.zip from Drive Tools for Windows.

Unzip it to a folder, say drivecleanup.

You will have two folders Win32 and x64 each containing DriveCleanup.exe for 32 bit and 64 bit respectively.

Since you have a 64 bit system, you will use the DriveCleanup.exe in the x64 folder.

Remove all USB storage devices from your system (except your Keyboard and mouse) and reboot.

Right click on the DriveCleanup.exe in the x64 folder and run as administrator.

After the clean up act, reboot and plug in your USB devices. The USB devices will be installed afresh. Check whether these get a drive letter that sticks. ( What you have done is to remove all non-present devices and drive letters associated with them and start with a clean slate.)

Tried what you suggested, still no change, drive visible in Disk Management, but manually assigned drive letter disappears almost immediately. Thanks for the suggestion though Jumanji.
