Hi,

at first please check if the removable storage manager is disabled.
If the Library is FC connected there are some recommendations with DP 5.5:
if scsiport driver is used -> disable devices in Windows Device Manager
if Storport Driver is used -> enable Devices in Windows Device Manager and install latest storport.sys from MS.
Try to test the Drive with Library and Tape Tools (Assessment Test). Install latest Firmware...

Regards
Dirk
