SYMPTOMS
When you use a tape library on a Windows 2000-based or a Windows XP-based computer, Removable Storage Manager (RSM) recognizes the tape drive but it does not recognize any media in the drive, even after you perform a full inventory. Because Removable Storage does not recognize the media, the media pools cannot be created under the free, the import, or the unrecognized system pools.

Note This problem typically occurs after the tape drive has been in operation for several weeks or months.

Because Removable Storage does not recognize the media in the drive, this problem prevents you from performing the following tasks:
 * Preparing new media
 * Reading a tape
 * Writing to an existing tape
 * Performing a full inventory

If you try to perform a backup, you receive the following error messages from Ntbackup:

There is no unused media available with the selected type.

-and-

Add unused media or click cancel to select another type.

If you move the tape drive to another computer, the tape drive still does not work and you may also notice that Removable Storage media pools are not created under the free, import, or unrecognized system pools on the new computer.



CAUSE
This problem may occur if the tape drive is reporting a &quot;dirty&quot; status. When the tape drive reports this status, it also reports that the drive is empty. When Removable Storage performs a recheck of the On-Media Identifier (OMID) during an inventory, if the drive does not report itself as having media, you may not check to confirm that the tape drive is reporting itself as dirty.

MORE INFORMATION
To confirm that you are experiencing the problem that is described in this article, watch the tape activity light on the tape drive and monitor the Removable Storage work queue while you perform a full inventory against the drive. To perform a full inventory:
 * 1) Insert a tape into the tape drive and wait for the drive to become ready.
 * 2) Start Removable Storage, and then click the tape library under Physical Locations.
 * 3) Right-click the library, click Properties, change the inventory type from Fast to Full, and then click OK.
 * 4) Right-click the library again, and then click Inventory.

Removable Storage reads the OMID on the tape. If you look in the work queue, you notice that Removable Storage performs an inventory and an Identify Media operation.

If you notice that the inventory and the Identify Media operation finish very quickly and if the activity light on the tape drive never flashes, you are probably experiencing the problem that is described in this article.
