SYMPTOMS
If you perform a backup operation or a restore operation by using the Microsoft Windows backup utility (Ntbackup.exe), and you back up to an Advanced Intelligent Tape (AIT) tape drive that has a Universal Serial Bus (USB) 2.0 interface, the operation may not succeed. If this problem occurs, you receive the following error message in the backup report:

Error: An inconsistency was encountered on the requested media.



CAUSE
This problem may occur if the USB tape drive uses the USB storage driver (Usbstor.sys). When a USB 2.0 tape drive uses Usbstor.sys, the driver experiences an input/output (I/O) queuing issue that may cause the backup or restore operation to be unsuccessful.
