Sony SDT-9000 Tape Drive
On the office server, we're using a Sony SDT-9000 for backups (SCSI variety), which came with a cleaner tape. Does anyone know how to manually use this cleaner? It's been six months, and it should be about time.

I couldn't get to Sony's support page but usually you just stick the tape in the drive and it does its thing. When the process is completed the tape is ejected.

I suppose you do not have a manual.

The manual says that the drive has a auto-notification system. I don't know if, when a cleaning is required, something should pop up on the screen, or whether that process works with Linux at all. To be safe, I'd like to manually clean the drive, if that's possible.

It's a good idea to clean the drive once a month. Michaelk is correct, all you need to do is insert the tape, it will eject when the cleaning process is complete. The host's OS dosen't matter, actually it dosen't even need to be connected to a host to be cleaned. The drive will notify you if it needs cleaning, via a certain sequence of flashing LED's, the manual should specify this. This will happen if the ECC rate increases dramatically, for example if you run a tape with debris on the media, the "clean me" message will be displayed. The thing to remember is a backup is useless if you can't restore from the tape, and waiting 6 months between cleanings will degrade the head, so the drive may not be able to read a tape that was created before the head got messed up. The rate between cleanings acutally depends on the hours of actual use. A drive that has average use should be cleaned about once a month.

Okidokes, I'll give it a try tomorrow.

You guys were right. The tape ran for 10 sec before being automatically ejected. Cleaning complete :)
