Hi,
Firstly I will give you the low down on the situation.
I am late on this recovery and have been given the drive after a computer shop tried to recover the data assuming that the drives were JBOD config. When I got the drive the HDD's were clicking and failing to spool up but USB was working, I immediately thought somthing was wrong with the 12V power lne in the PSU, upon investigation this was the cause. Having now plugged this up to a couple of decent PSU's I have found nothing worong with the enclosure. Due to the fact it has been opened up and looked at the RAID 0 config is all to pot and one drive I believe has partition damaged.
Okay, on to what I have done.
It would also appear that the drives are in a random order within the enclosure and I was stuggling to find drive 0, although I think I have sorted that as its the only drive with readable partitions on it. Secondly I am having issues finding the stripe size, I have tried numerous sizes, 16 upto 256 with mixed results. The Jpgs are all corrupt (shearing!) no matter what stripe size I am using. My knowledge of HDD recover is limited, but I know some of the do's and don'ts and am currently getting fed up of having to re-image the disks as each one takes about 22 hours

I have purchased an identical LAcie HDD with the intention of backing up to this, originally I thought maybe the board had fried so intended to swap the drives. Now the power has been found as the problem I do not believe any benefit will be gained from this.
I am using R-studio for this recovery.
Any advice would be greatly appreciated as an entire business and close personal friend's livelihood is in my hands, no pressure :s (I have already preached the backup speach)

Hardware is as follows;
Lacie 1Tb Big Disk Extreme+ (tripe interface USB, Firewire400/800)
2 x Samsung 500GB SATA drives
