As I have frequently reported on this list, I had nothing but trouble with HP DDS-1 drives. I had 4 of them, and they lived between 5 and 8 months. That changed when I got an HP DDS-2 drive, which lasted over a year. I've been using an Archive changer now for 15 months, and haven't had any trouble (although I'm beginning to wonder if the original topic isn't biting me too: I'm only getting 2.7 GB on a 90m tape, too much for no compression and very little for compression). > HP uses OEM Sony drives in their cheap DDS devices designated for > PCs, and own HP drives in RISC servers.

I did that once on my first DDS-1 drive--it came without instructions, and nobody knew it needed cleaning. It didn't do any better or any worse than the other ones, which I *did* clean.
