Recovering data from a broken mirror RAID

[Anonymous]

I am trying to recover some files from a broken mirror. One of the drives in the two drive mirror died completely (not showing up at all in any utility) and the left over drive seems to be a little flakey. Mounting, repairing, or imaging the array failed. When I couldn’t mount the raid or the disk by itself I tried diskutil removeFromRAID. While that was doing its thing, it kernel panicked and left me without a RAID set and the disk still type Apple_RAID. The RAID was formatted with 10.4 server as version 2 (IIRC) and was running 10.4.5 before it died. I’m currently running 10.4.6 server on the drive I’m using to attempt to recover the data.

barf:~ agsupport$ sudo diskutil list

disk0 is an external firewire drive
disk1 is the part of the mirror raid that I’m trying to get at
disk2 is the boot drive I’m using the access the drive

Thank you for any help.
