SYMPTOMS
After you install a tape device or other removable-media device in Windows 2000, the device may appear in Device Manager but not in Windows 2000 Backup. When this occurs, your only choice in Backup is to back up to a file. The removable-media device is not an option.



CAUSE
All removable-media devices are handled by Removable Storage Manager (RSM). Unless the tape device or other removable-media device is recognized by RSM, Windows 2000 programs (such as Backup and Remote Storage Server) cannot use the device.



RESOLUTION
For RSM to recognize a removable-media device, the device driver for that device must use the Windows 2000 driver extensions. Therefore, legacy device drivers designed for Microsoft Windows NT 4.0 and earlier versions may not function properly.

If the device is not on the Hardware Compatibility List (HCL) for Windows 2000, please contact the device's manufacturer for updated drivers that include the required Windows 2000 extensions to work properly with Removable Storage Manager.

NOTE: Some third-party backup solutions install their own drivers for the tape library; these may not be RSM-aware. Should this happen, the third-party backup solution will function without RSM, but the tape drive listed in RSM under Physical Locations will appear with a red X indicating that the device is not working. If you want to use the tape library again with RSM, you must uninstall the third-party tape drivers and reinstall the Microsoft RSM-aware drivers. After you do this, RSM and Ntbackup.exe should be able to access the supported tape drive again.



MORE INFORMATION
For RSM to recognize a removable-media device, the device driver for that device must use the Windows 2000 driver extensions. Therefore, legacy device drivers designed for Microsoft Windows NT 4.0 and earlier versions may not function properly.

NOTE: This issue may also occur after you upgrade the tape driver by using one from a third-party OEM. The %SystemRoot%\Setupapi.log folder contains the pnp-id of the tape device and the name of the .inf file that is used to install the device driver for the tape device.

If you want to revert back to the native Windows 2000 driver, remove the tape drive using Device Manager, locate the OEM .inf file (where  is a number) for the tape drive in the %SystemRoot%\Inf folder, and then move it to another folder. After you move the folder, use Device Manager to scan for new hardware. It detects the tape drive and use the Windows 2000 native driver.
