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.

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...

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.
