I have more that one HD in my computer… If i take one HD that is encrypted, and put it in another computer, will i be able to access that HD in the other computer…???
You should be able to access the encrypted partitions only if you boot from that HD and you don’t have other encrypted partitions in the system, on other disks. If you have other encrypted partitions, in order to be accessed they must all use the same password & authentication type.
