Tapes showing up as Unknown Media and seeing Cyclic Redundancy errors in event log
Posted on 2008-10-09
Ok, Just got a new tape drive Dell SDLT320. When I installed symantec's driver from website, the driver shows as "QUANTUM SDLT320" even though it says Dell on the physical tape drive. Is this normail?
Anyways, the main question is. I have about 10 Quantum Super DLT 1 tapes that all show up as "UNKNOWN MEDIA" when I run an inventory. These are refurbished tapes but am a little doubtful all of these tapes are bad. I tried doing a QUICK ERASE MEDIA with no luck. I am also seeing many event log errors in the system log as follows-
EVENT ID: 7
DESCRIPTION: The device, \Device\Tape0, has a bad block.
One funny thing is that 1 of the 10 tapes seems to inventory as a "blank tape" and I was able to label it and was even able to run a full backup. The next night this tape failed with the error "Error reading/writing data from/to the media." and showed the same dlt-VRTS errors in the system log the same as the other 9 tapes.
