I have an HP SureStore 70 (Quantum DLT7000) tape drive. I upgraded the firmware using HP Library and Tape Tools. After the upgrade, the drive worked on two test jobs. I started a third job and left it. Today I found it with all lights on the front blinking and the job (running in Backup Exec 10.0) showed failed. I had to cycle the power to make them stop.
Now the drive won't do anything. I can load/unload tapes, but I never get more than the "Tape in use" LED. When I load the same tape into a working drive, the "Tape in Use," "35GB," and "Compressed" LED's all light. Also when I load the tape into the good drive, it spins at high speed for several seconds while it processes the tape. The bad drive spins once at high speed, makes a couple of slow turns forwards and back, and then stops.
When I view the drive in HP Library & Tape tools (which I used to upgrade the firmware in the firstplace) it says the drive is limited to only a few tools because it is in "boot code" and not all diagnostic features are available. I attmpeted to use Libary & Tape Tools to update the firmware again, but it failed.
