I created a mirror raid in Mac OS X 10.4 consisting of two stripe raids. After moving all my data to the new mirrored drive, I rebooted the mac, only to find that one drive from each stripe raid had their partition data missing. So I now have two copies of "A" and no copies of "B".
I need to find a way (probably via Terminal) to re-create the partition data on those drives. Is this the way to do it?
I've tried using Data Rescue X, which is able to see the two stripe raids (the mirror raid that used to be formed of these stripes has been lost to oblivion). A Thorough scan in Data Rescure is reported to last 53,000 minutes... and it crashes after 8hrs of hammering my Dual 2.0 G5 (4GB ram)
Diskwarrior for Tiger is not out yet, but to my understanding, it needs the partition data to do its thing. I'm not aware of any mac app that is able to fix/create parition data.
The drives in question are all identical Maxtor Diamondmax 10, 250GB, about 3 months old. They were all formated in Tiger, where the RAID was created using HFS+ Journaled.
