ok so i have an old power mac G4 with 2 80GB drives and want to setup a raid. I need to know if I can raid two drives with mac os x 10.3.9 alredy installed. The only thing is that I cant reinstall 10.3.9 because I do not have the install disc for that version of os x, but on the other hand i do have the install disc for 10.1.3. can it be done with this version of os x. can you tell me what i have to do to get it done, because i want to use the old box for a network drive for extra storage to my windows PC.

thanks for any help you can give in advance.

Don't bother.. raid0 will waste 80% of your cpu cycles duplicating every write operation.

ok varnull, i think you might of missunderstud what i am trying to do. what i want to do is make 2 drives in to 1 big drive.

So let do the maths

80+80=160-5=155

so the 5 gig for the os and 155 gig as a network drive.

thanks for the reply

No, you misstated what you want to do. You might have specified RAID 0 in order that people would properly understand what you were trying to do.

RAID 0 = striped data (1 logical drive that is 2 x the smallest physical drive) Not a "True" RAID because it is NOT fault-tolerant

RAID 1 = mirrored data (1 logical drive that is 1 x the smallest physical drive) is fault tolerant

RAID 0+1 striped and mirrored (requires 4 drives)

I don't believe that you can create a RAID 0 after the fact.

However, it appears that you can do RAID with 10.1.3

I hope that this helps.
