Hello,

I have an XP Pro SP2 home computer with a RAID0 setup (2 250GB HDDs, SATA i think) on an ASUS K8N-E Deluxe motherboard. The computer was made back in 2004 and i can't find a lot of information about it from the guy who build it for me.. Sorry about this.

The problem i created was some months ago when i tried to add a new HDD on my computer. By mistake while i was trying to connect the new HDD i unplugged one of the 2 HDDs cable (not the power one but the one connected to the motherboard) and connected the new SATA HDD on the raid controller (.. yeah that was stupid, but i didn't know back then and didn't notice it..), which i didn't notice at that time, and when i turned back on the computer the RAID0 connection was obviously lost. Removed the new HDD and reconnected the cable but the connection was still lost. Tried to reset the Bios (CMOS basically?) but that didn't work out well. Plus i can't find any option in the BIOS to manually reconfigure the connection between the 2 HDDs.

Now.. A couple days ago i've been told to try some reconstruction programs and didn't manage to do much with then until i found ZAR! In order to run ZAR i unplugged the HDDs from the raid controller and connected them on the SATA ports. (I used the same PC that the HDDs are broken by installing a new IDE HDD on it).
Ok so the PC found the 2 HDDs and was actually able to see 4 partitions (which is not correct since i had 3 partitions with the 2 HDDs, i do NOT remember exact details though..). So i run ZAR, chose the 2 HDDs and that are raid0 and started to run the program. I reached until the "Select a physical device" screen. In there i had to manually define a volume, and i had no idea what to do so i right clicked on the HDD and tried to click on the search for a volume (? or something similar) option. Well when i clicked that it said i got an error and the whole program closed..
After that i went to my computer and saw the HDDs once again. I could actually now see the files in the partitions but with 1 small mistake.. I could see the main ex OS partition twice? Although it seems to be splitted in half and see it twice.. So there is a D and E which is supposed to be the C and then the F and G which are the old D and E (the C is the IDE HDD).

I am wondering what should i do now? :/ Any ideas?

Thanks,
BL

If you split the RAID, you can no longer use the partition information from its member disks. You should just stop looking at the partitions before the array is rebuilt.

And, I did not quite understood at which step you first run into the trouble. Could you please look up the RAID recovery tutorial (http://www.z-a-recovery.com/raid-recovery-tutorial.htm) and tell me the the exact step number? Somehow, it feels like you have applied a procedure designed for a non-RAIDed volume to a RAID.

The trouble was caused in the 5th step. The HDDs were meant to have a RAID0 configuration.. :/

Do you remember how many partitions were originally on the array?
If there was one, then

Right click the list, select "Define volume manually"
A prompt pops up, select "There was only one volume", click OK to close prompt.
This returns you to the list, a new item will be added to the list ("Unknown" filesystem, "User input"), select it and click "Next"Otherwise, right click the list select "Scan for missing", then wait and it discovers whatever volumes still remain in there, populating the list. When it finishes the search, select the best match for what you remember was on the array and click "Next". You need to repeat the procedure for each volume.

Please try either of those and report back with the error messages, if any.
