Hello all,
Since WD doesn’t make any official software for My passport in Linux, there’s now an unofficial port of the wd-security for Linux.
Note: This utility is completely “as-is”. It only supports a temporary unlock of the encrypted WD My Passport drives.
It has only been tested in Ubuntu 13.04 or above.
Please test it and see if it helps.
You can grab the code here: wd-security for linux
