Knowledgeable RAID diagnosis requested

If you have 2 discs, you can only create 1 RAID 1 array, or 1 RAID 0 array.
You can't have a RAID 0+1 (or 1+0) array as this requires 4 discs minimum
and you do not have enough discs.


So, when you say raid 0+1, what are you meaning?

Well to tell you the truth I'm not sure what I mean. On my m/b, on boot one
is given a chance hit control-F which takes you into a setup for the
SATA/RAID. You can automatically set RAID0 or manually set it up. All I did
was to go into the manual setup and did whatever it allowed me to do to set
two different arrays using the two disks. All I wanted to do was get the
drives 'separated' so I could test them to see if I had a drive problem. I
was then able to boot and initialize the drives in XP, format each of them,
read and write to them like any IDE on my system. Since I didn't really care
about Raidin' them I didn't pay that much attention to nomenclature so I may
be mis-characterizing them. My objective was to split the siamese twins
under RAID0.

Thanks.

I'm leery of adding anything like a new board to this one since so far I've
tried two different controller cards and neither of them worked. Looks like
I will go ahead and upgraded to a new m/b and athlon64 chip.

Thanks.

Excepting if the raid has been built a different raid controller may not see
the raid, and if it does it may corrupt the raid. - Info from Adaptec,
further they state if changing raid controller, sys must be rebuilt as
otherwise they cannot guarantee the raid -

Either of you stupid top posters ever consider trimming your posts?

Nah. Too much work.

No, Mercury did NOT write that, you idiot.

Please learn how to quote, and how to post, you clueless idiot.
 
that's all you have you contribute? STFU
stupid is people wasting others time by posting their OPINION of how things
