Hello,
I’m trying to recover data from a MyBook Studio II, Model wd2000h2q-00 which contained two 1 TB Western Digital Green drives.
This external storage was used on a Mac. It does have a GPT table, and HFS+ partition and was much probably in RAID-0, totalizing 1893 GB if remember well.
The number of defective sectors was about 44 MB for drive A, which had the GPT and 4096 bytes for drive B.
The cloned drives that I’m currently using were checked as free from defective sectors.
For the data recovery, I’m of course working with the clones and not the original drives.
I tried probing the drives to automatically detect the parameters of the RAID-0, but they were several possibles and no significant result. Most files were binary ones or in markup languages such as xml, making difficult to detect discontinuities on the drives in order to guess the length of the stripes.
After some tentative with 16 sectors chunks, I could use the reconstructed RAID to access the content of two pdf files in hexadecimal.
I could find within them the file start signature “%PDF” at 0x800 and 0x1800, i.e. with an offset of 2048 bytes for the first “reconstructed” file, respectively 6144 (=4096 + 2048) bytes for the second one.
This make me think that the stripes could have been picked and reassembled in the wrong order.
Also the size of stripes could be wrong.
Can someone tell me :
- Which are the “factory settings” for the RAID-0 used by this storage (i.e. size of stripes, offset, a.s.o, …) ?
- If there is some software/driver that I could use to try accessing this storage on Windows (despite it was used on Mac) or possibly on Linux ?
I keep hope that the damages to the filesystem are not too important and because the cloned disk are sane, the storage could possibly work again.
Thanks a lot.
