I have a primary master hard disk partitioned into 5 partitions (C E G H and K). It is a dual boot system. I have two separate installations of Windows XP installed on partition C and E. I have encrypted partition H only using PGP Desktop. Now when I boot my computer I get asked to enter my pass phrase before the system will boot up. I wish to know whether I can now safely assume that no one can access the data I have on partition H of this hard disk, even if some one takes this hard disk out of my computer and try to access data on its partition H using this hard disk as an external USB hard disk. Thanks for your help.
