So if you have locked your WD My Passport then you will stay assure that if someone gets your drive then he can't unlock and view your files. Technically it is impossible to recover any file after this scenario. What happens actually is that the software permanently deletes the key used for encrypting the data stored on the external drive. No file can be recovered when you erase a password protected WD My Passport.

In this situation, if you erase the drive then it will be a secure delete operation. Whenever the WD unlocker software registers 10 invalid password attempts it gives you the option to erase your My Passport. Without the password, the drive can't be opened to view files. The security of the drive is locked with the help of a password. WD My Passport uses 256-bit hardware disk encryption encrypted with a key. One such way is to install a password on your external hard drive. Taking backups of your precious files is not enough, you should also secure it everywhere you are storing it. Nowadays external hard drives come with built-in hardware encryption for data security. Some years ago external hard drives were like USB flash drives with no encryption. As external hard drives can store large amounts of data then it is necessary for us to protect the data stored on them. Regardless of the user-password, KEK or DEK.Western Digital My Passport is one of that external hard drives that come with 256-bit hardware encryption. After resetting the ATA password, we had complete access to the decrypted user data, as the SATA chip decrypted on-the-fly. We located the location of the ATA password and some (unknown) connection to the AES password in different SAs from the internal 2.5' SATA HDD. Nevertheless, this is not an off-the-self solution offered, so we worked our way through to the AES protection. If the user does not supply a password, the user data is inaccessible when connecting directly to the SATA ports.įinally, we were able to bypass the ATA password with commercial tools. The bridge is therefore doing user authentication by setting an ATA password, once the user generates his password. The data access is restricted by a set ATA-password in the SATA-HDD.

We tried to connect the SATA HDD directly over the PCB for accessing a raw sector, but did not succeed.
