Also in the logs there is a drive cleaning request about every 10-14 days is that normal?
No, I don't think is normal, unless you run your tape drive 24 hours a day in a bad/dusty environment.
Is this a stand-alone drive or in a library? If it is in a library, is a good cleaning tape available for BE to clean the drive when the drive requests it? A dirty drive generally presents clear text alerts in BE that make it pretty obvious what is happening. You may need to do some investigating and/or testing with the hardware vendor diagnostics program.
