External HDD protection

[dm-dutchman]

Hey guys,

 

I want to protect an external HDD with a password, so people can borrow it and only the people with the password can get data off it. But i would like to protect it in a way that only i can change the password on the HDD.

 

Hope you guys know a solution..

You are asking for a boomerang disk where you give it away with access passwords and expect it back intact. I really do not think it can be done.

User restrictions are limited by the OS not the removable disk, the admin/root on OS can over-write it.

Encryption typically just has one private and one public key, I am not aware of a disk encryption solution that has a third admin key, which is what i think you are asking. It certainly is possible to add a third key into some algorithms so you could tell if your disk has been tampered with, but I do not believe it has been done for filesystems, and it would not stop an admin from overwriting it would just let you know that your disk has been messed with.

If you want to hand out encrypted data in a throw away way, burn it to a DVD or put it on a cheap shitty usb flash. Im sure Mega has a new iteration of this as a cloud solution.

The disk will be used by only 2 people, but i want to make sure that they are the only ones who can get data off it, but i don't want them to change the password on the drive. So i would like to be the admin of the drive.

We are going to use a different system, so this topic may be closed.
