Re: Intel Matrix Lvl 5 Raid w 4 discs

R-Studio Emergency needs to be activated to be able to write data on disks.

How? - I got my technician key, downloaded and created the TUI emergency version. I can only view the first sector, not scroll, not go to a sector, and certainly not edit anything on the disk - what am I doing wrong ...

Re: Intel Matrix Lvl 5 Raid w 4 discs

Ok, have faxed an order for the technician version, so I can try that, and hopefully recover files. The scan is now 41% (after 16 hours) into the raid-set, and have a few complaints about unexpected MFT records (most likely from the degraded parity blocks) - so it remains to see if we can get the ...

Re: Intel Matrix Lvl 5 Raid w 4 discs

Hmm, typical, after a days forensic work, I finally found the paper: http://www.intel.com/assets/pdf/appnote/310855.pdf

Re: Intel Matrix Lvl 5 Raid w 4 discs

Found the layout, it's left asynchronous. But since the raid-set is degraded, parity sectors are plain code.

Intel Matrix Lvl 5 Raid w 4 discs

Hi, have managed to create images of the four drives. At the 2nd to last sector the drives in the array are identified with their serial number, so I guess the order of the discs is revealed there.

But when imaging, disc 0 had 16 bad sectors, and disc 1 had many more; disc 2 and disc 3 were intact ...
