Question Can ZAR help me? -RAID 0 recovery

Hi, I was curious is ZAR can help me with the following problem:

I have a DX58-DS4 motherboard. That apparently has a bug with BIOS flash when using on-board RAID.

Systm info:
DX58-DS4 motherboard
ICH10r (onboard) in RAID-0 with 2x 640 GB drives.

Idealy I would like to FIX the existing RAID set and go on with my life. Also, I dont have a Terabyte drive to do data recovery.


Problem:

After BIOS flash, you must get into the BIOS on the very first boot and re-enable RAID. If you dont (I didnt - their manual neglects that info) it does something to one of the disks where RAID no longer sees it as part of the set. I'm not sure if it simply wipes the first few bits, or completely wipes out the fat table. Point is, RAID recognizes disk 2 but claims disk 1 is no longer part of the RAID set.


Question 1:
Can I connect both of the drives to another system using SATA (it doesnt support raid) and have ZAR (attempt to) fix the RAID-0 set so I can use the disks in the old system?

Question 2:
Can I boot off a DOS or Win PE cd on a broken system and use ZAR to recover it? Would it even matter where the drives are connected?

Question 3:
Also, my father may have zar 7.3, could I use that to accomplish the same task?

Apologies for the long question,
Thank you

ZAR does not fix the volume. To go with ZAR, you need a terabyte blank drive. No other way round. So I guess the answer is no.

1. No. ZAR does not "fix" anything. ZAR is a "data-extraction" tool. The extraction process would work fine on a non-RAID system.
2. You can boot off Win PE CD and run ZAR from it. If you have a good 1TB disk attached with USB, you can than copy data on that disk. If you use, say, 500GB disk, you would need two passes.
3. Send me a private message with his full name and email address used with placing the order (if practical/if still available), and I will issue a 8.4 key (there was a change of keys around version 7.9, you get a new one for free but you have to ask for it).
