Hi Aldo, I think my response may take the discussion in a different route (I think you are looking for specific stats). However, it does address some of the questions you bring up.
The only difference between an FDE drive and a regular drive is the ASIC on FDE drive that process the encryption. The platter, the servo, the slider, the head, the control board are all the same as in that of a regular drive. So, as long as you have the encryption key backed up someplace outside the FDE drive, the reliability of the FDE drive and the recovery from failure are similar to a regular drive: a) When image/re-imaging a computer, one has the choice of deactivating the encryption prior to this process (or authenticate to the pre-boot and do a soft reboot right after). So, no major difference here. b), c) Given the hardware itself is the same, the electrical failure stat will be the same. If it is a complete hardware failure, the strategy is not to bring the drive to its original state, but to recover the data. This will require forensic access to the drive, which will recover the raw data, but for the FDE drive, the encryption key would be required to make sense of it all.
