Hey all!
My Maxtor 60GB drive recently died (has issues spinning up) so I'm going to order a replacement from Maxtor (still under warranty). I need to transfer ALL (including sys) files to the new disk.
My question is:
Can I use software RAID (in Disk Utility) and set up RAID Mirroring on the 2 drives to achieve this? I did notice that in Disk Utility Help under "Selecting a RAID scheme" it notes that "in most cases, you cannot use RAID on the startup disk.
If that won't work, give me some other suggestions...
Or should I just use the terminal (ie cp / /volumes/newhd)???

RAID will not work for this purpose... you need to use one of the following:
ditto (command line)
make a disk image of you rHD with Disk Copy, and to push it to the drive (not a great idea unless you are making many copies)
Use Rsynx/Psync to move the data over.

Actually, RAID should protect you, in theory, from harddisk failure although it won't protect you from nonhardware problems such as file system corruption.
I don't know if apple's implimentation of RAID1 is any good for this though.

It won't be useful for what he is doing. He wants to set up a temporary RAID mirror to copy the contents of one drive to another. This won't be useful because when you break the RAID you will have to reformat the drives.
Carbon Copy Cloner is his easiest solution.
