System: Debian Squeeze

What's it for: A System where any new disk is DoD Wiped.

I'm looking for a method to fire a command on a disk error that the kernel throws, sometimes we get bad disks and it just needs to be scraped.

Common lines in the logs are

Jan 15 10:34:33 drivekiller9k kernel: [339274.100020] usb 2-3: reset high speed USB device using ehci_hcd and address 51
Jan 15 10:34:33 drivekiller9k kernel: [339274.233729] sd 176:0:0:1: [sdl] Unhandled error code
Jan 15 10:34:33 drivekiller9k kernel: [339274.233733] sd 176:0:0:1: [sdl] Result: hostbyte=DID_ABORT driverbyte=DRIVER_OK
Jan 15 10:34:33 drivekiller9k kernel: [339274.233737] sd 176:0:0:1: [sdl] CDB: Write(10): 2a 00 00 34 b8 70 00 00 f0 00
Jan 15 10:34:33 drivekiller9k kernel: [339274.233781] __ratelimit: 20 callbacks suppressed
Jan 15 10:34:33 drivekiller9k kernel: [339274.233815] lost page write due to I/O error on sdl

I would like a method where I could just run a shell script to kill the wiping process and write to a log, what would be the proper method to do this?

You can use smartmontools to monitor your disk health, using the provided smartd demon. Some examples.

you could use the Shell execute ACTION of rsyslog to trigger actions (e.g. your recovery script) on certain log message entries. See man rsyslog.conf for details.
