Drive letter keeps changing on Windows Server 2012

Question

We require to take backup for client regularly on L drive.We assigned the drive letter 'L' from disk management but when the next tape is inserted for next day backup it goes back to H again. We keep changing the drive letter to 'L' but drive letter automatically becomes H every time a new tape is inserted.

Didn't know how to fix it so we rebooted the server but that didn't do any good.

Any help would be appreciated.

In this order:

Insert tape and mount the file system
Next, make sure the drive's system restore option is disabled for this drive.
Then, regedit then search for HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices and rename the corresponding /DosDevice/H: entry to /DosDevice/L:

Windows system restore will reserve the hardware the drive letter, Disabling it on the drive will cause the system to read the /DosDevice entry. With some group policy option settings, you must disable system restore on the whole system, then reserve the drive letter in disk management.
