Only hddguy was closest to the secret.
Old Lacie with 4 250Gb IDE drive almost always has same raid parametres by default. Reclaime always fails with this.

hmmm, I did come across something somewhere where someone mentioned a 4 disk 500gb model have two raid modes but I've now lost the link. any more direct pointers you can provide in this regard?

JBOD(raid0(disk1+disk2) + Raid0(disk3+disk4))

The BPB at offset 0 is indicating that there are 63 "hidden sectors". This means that this Win 7 boot sector should be located at physical sector 63, not 0 as your image would suggest. In fact it looks like you are showing us logical sector 0 of a 1TB NTFS logical volume. That said, Windows 7 defaults to sector 2048 rather than 63 as the start sector of the first partition.
The size of this NTFS volume is ...
0x74715485 x 0x200 = 1 000 235 141 632 bytes
The MFT is located at cluster # 0xC0000, and the MFT Mirror is at cluster #2.
There should be an identical copy of this boot sector at the end of the partition, assuming that there really is a 1TB NTFS volume.

OK, I believe I've found the order and stripe size for the two raid 0 arrays (disk 04 & 01, disk 03 & 02, 128kb) but not sure of the stripe size / offset for the JBOD...

Old discussion but sharing is caring ...
After spending some hours I wanted to share my success with the help of this page.
2 RAID0 and a final JBOD , Block Size 128KB or 256 sectors, all offsets 0
JBOD ( RAID0 ( 1st row ) + RAID0 ( 2nd row ) )
Check images for RStudio Raid config.
Thanks alot to everyone , hope this helps more people in the future.

OP here, just wanted to give thanks to macwest for posting the details on the RAID0 + JBOD config on these old models. Just came across a 2TB version of this model and this discussion helped crack the case.
