Unlock FDE

InVirtuel constantly brings innovative solutions for the data recovery market, HDDSYNC is not a unique development.

Unlock FDE is a software solution used by our technicians, enabling to access data on encrypted hard drives (with the “FDE” system as Full Disk Encryption).

Success story

I just closed a case as successful on a Seagate Momentus 7200 FDE.1 (ST9250424ASG). This disc was encrypted with a password requested at the boot step (not the ATA password on Bios). Unfortunately the number of bad sectors has increased in the boot area. The client had no further access to Windows (the client already had problems on the Windows partition before …),  or to the boot partition that requires the password for unlocking the disk.

So, I started to retro-analyze this protection system and make a simple development to unlock the disk without having access terminal (because it’s also blocked) and without help of any other software (dedicated tools for firmware access do not yet solve this kind of problem).

After a significant research activity, I came up with a simple solution (called Unlock FDE) to unlock the user’s data partition “with the USER password” and directly under Windows. All the ATA commands required for this “access” are (of course) “Vendor Specific” and have no documentation available on the Web…

Eventually, I was very lucky in this case, because the disk only had bad sectors (but not that many), but it was impossible to access this disk in a conventional manner nor with advanced data recovery tools.

A few words of history

  • 2007 : first cases of several Maxtor hard drives with seized and failed motors
  • Search for an existing technical solution : none
  • Late 2007 : our R&D department  came up with specifications prior to the development of HDDSYNC
  • January 2008 : creation of a HDDSYNC prototype, followed by different tests and tuning steps throughout 2008
  • Success demonstrated and validated on failed motors of hard drives branded Maxtor, Hitachi, Samsung and Seagate 7200.11, 7200.12 (the inox equipment commonly used with physically damaged hard drives is not working with these brands)
  • 100% success rate over the last 2 years on hard drives with unscratched platters (list of compatible hard drives – non exhaustive)
