I have connected a Dell LTO-2 Auto-Loader in Windows 2003 and installed the correct drivers et al. It works fine with Backup Exec that is also installed on the server, but I can't mount or write to any tapes using WIndows Backup. I think this may be due to BackupExec being installed as well and the type of header file being written. Whenever I attempt a mount in RSM, it fails with an Event 127, Unexpected on-medium identifier. I tried deleting the BE settings in the registry as per article http://support.microsoft.com/?kbid=867702
and restarted the RSM service but the error is still produced.
The comapany I work for has never used Auto-loaders before, and my boss is so smug that its not working first time after my recommendation!! ;)
