safer and surer
Authored by: mrdelurk on Nov 04, '07 04:59:11PM

The task was, get rid of my OSX 10.4.10 dual Mac G5's system drive (it's both a puny 160 Gig and Maxtor - two major strikes) and replace it with a RAID of two 400 Gig Western Digital SATA HDs I freshly bought.

I tried the "clone System to external drive, boot from it, install RAID" approach plink53 suggested, it didn't work. I had the system HD cloned both to a FireWire and an USB external hard disk, neither budged an inch at boot time. Even if they did, Disk Utility wouldn't let me add internal SATA drives to the RAID window, only external FireWire ones.

Next I tried inviscid's "enableRAID, restore to mirror, restore to system HD" approach. It didn't work either. After the enableRAID step, Disk Utility still didn't report any kind of RAID, degraded or not. Even if it did, the 400 Gig internal SATA drive which was duped from the 160 Gig System drive with the Restore command would not boot the computer no matter what I tried.

So these RAID concepts are nice, but the feedback from the trenches is, they don't necessarily work.
