Device\Cdrom0 has a bad block

Hi. I have an IOMEGA RRD drive that uses Rev drives. The drive is not reading any of the REV drives that I put in. In the event viewer, there is an error Event ID 7 "The device, \Device\Cdrom0, has a bad block. the last time this happened, I updated the drivers and firmware, rebooted a few times, reinstalled my backup software and finally got it to work. Now, it is happening again and I am wondering if the actual drive is going bad. I don't have access to another Iomega drive, but I find it hard to believe that all of my REV drives are bad (I have tried 10 of them). My connections seem to be seeded properly.

Thank you.
