Hello,

I'm working on a WD My Book Thunderbolt Duo 2x 4Tb that was accidentally quick formatted on a Mac. It seems that the RAID parameters used when it was formatted are different than the original. Even when I RAW scan it the files I find are only fragments.

Does anyone know what the default RAID 0 stripe size is on these? Model WDBUSK0080JSL-H0.

Thanks in advance guys.

Some of the higher end WD MyBook raid drives are a single sector (512kb) stripe.

Ok, turns out it was 32kb stripe size. Same as it is after formatting. It's just that the drive order got swapped.

:D

That's indeed a high-end sector size :)

Oops! Of course I meant 512 bytes :-)

That's a combination of fat fingers and two bottles of red :mrgreen:

It's OK, I actually knew what you meant.
