X25-V Encryption

idata — Mon, 03 May 2010 22:25:46 GMT

Not sure where to direct this question so I thought I'd ask here. We recover data from various NAND based devices including http://www.recovermyflashdrive.com/usb-flash-drive-recovery flash drives and http://www.recovermyflashdrive.com/ssd-solid-state-drive-data-recovery solid state hard drives. I had some free time and was looking at a X25-V solid state hard drive and noticed the controller (PC29AS21BA0) appears to encrypt the data stored on the NAND memory chips, in the technical documentation I couldn't find any reference to this.

It appears to use a streaming cipher but I can't figure out what encryption method the drive is using. It also appears that if the NAND chips prematurely fail (ie: the data in specific areas become damaged beyond what the ECC algo can repair) the drive shows up with a capacity of 8MB.

Can you provide me with the contact information for someone who may be able to answer these questions?

What encryption method is used?

What is / how can I retrieve the key when recovering the data? Does the PC29AS21BA0 controller in the X25-M G2 series also encrypt the data when writing to the NAND chips?

Thanks,

Jeremy

Hello, I would like to let you know that yes the Controller uses an algorithm to distribute the information on the NAND chips but how exactly is information that Intel® cannot disclose.

Therefore there is no method to recover the data once that the drive is damaged.
