I'm trying to use HDDerase. I want to wipe my HDD, except for the recovery partition. It's my understanding that HDDerase will not touch the recovery partition. Is that correct? Also, I'm getting some conflicting info about the meaning of Enhanced Secure Erase. According to the HDDerase ReadMe.txt: Q: What is the difference between secure erase and enhanced secure erase? A: Secure erase overwrites all user data areas with binary zeroes. Enhanced secure erase writes predetermined data patterns (set by the manufacturer) to all user data areas, including sectors that are no longer in use due to reallocation. ***NOTE: the enhanced secure erase option is not supported by all ATA drives. However, I have also read that Enhanced Secure Erase is where the drives encryption key is deleted therefore making the data unrecoverable. It only takes a few seconds. So, which is it? Is the encryption key just deleted or is the drive overwritten? Thank your for your time.
