There is one 40Gb 2u2s, 2x 500Gb3u2s and a 1Tb d2 with AES encryption.
My goal was to reuse the disks as the personal data were not important.
I checked the small disk and quickly realised that there will be more problems reusing it than gaining access to the data. I contacted LaCie, explained the situation and of course the answer was that there was no solution to get the data and that for the older drives out of warranty it was to expensive to get them "fixed".
So I decided to open the 2u2s drive, as there was no mention of encryption I was pretty sure that the data will be easily accessible.
Disassembly of the LaCie 2u2s
Flip the drive over, so that the biometric sensor is on the bottom and the USB and power connector are facing you. Carefully remove the two rubber pads and remove the screws under them. Now on the other side you have to carefully force the plastic with a small flat screwdriver.

Getting the data was trivial. I connected the drive to an USB IDE adapter. There is no partition defined, I suspect it's hardcoded in the hardware, or better there should be 3 partition, one FAT partition on which the Windows software resides, one for the MAC software and one "protected" partition. In fact I didn't care, although the partition layout should be easily guessed I just run PhotoRec on the entire device and in just 30 minutes the whole 34Gb data from the disk were safely stored on my desktop.
The next step is reinitializing the device. I already searched for the STM chip, but could not find any datasheet.
Any help is welcome ;-)
