reuse encrypted hard drive?
If a hard drive, say from a laptop, has a hard drive password, is there a
way to wipe the drive of the password, the data, and everything so the drive could be reimaged? We are testing some laptops from Dell, Toshiba, HP, Lenovo and Micron, and instead of erasing the drives I figured we could just put passwords on the hard drives within the BIOS and the manufacturers can wipe the drives. My one person told me even if you plan on wiping the data off the drive you gotta have the hard drive password. Can anyone confirm this? |

Its the drive that does that. Not necessarily desirable to lose the recovery partition tho.

Its true for writes to the drive, but not to get the drive to wipe itself. |

reuse encrypted hard drive?
Thanks for the quick response, Rod.
We are not worried about the system partitions because I expect the manufacturer can run a rebuild disk or similar which will create the original partitions. I just do not want them to easily read the drives when I send them back and I don't want them complaining that I've damaged the system by setting a password.. I want them to have to format them to make them usable again. I was hoping to do this instead of using a drive wipe program. It's low security stuff so maybe a simple drive wipe is the answer.

Unofficielly, several companies offer software and services to do so without password. Google(remove hdd password) will show you some. Some also claim they can do this without data loss, and there is good indication they really can do this. If you want to secure what is on the disks, you need disk encryption. Incidentially disk encryption allows you to wipe the drives without any password. Arno |
