I'm planning to buy an external HDD with hardware encryption, namingly the WD My Passport Ultra 2TB. On the WD website the information about the encryption is sadly scarce so I'm asking here.
- How secure are these encryption implementations in general (I think the above mentioned model uitilizes
- How inter-OS friendly is the en/decryption and the subsequent accessing of the data (Windows, Linux/Unix and possibly MacOS) ?
- Is the unallocated/empty space on the disk encrypted as well, or just the sectors where data is allocated?
