This may not work but is definitely worth a try. When you said that your old computer died but you still have the hard disk, I assume that the OS on your old hard disk is not corrupt but it was just a hardware fault or something on your old computer.
I do not know if encryption keys are specific to hardware or not, hopfully someone better than me will correct me if I am wrong. If they are not, I would recommend:
- Boot up your new PC using your old OS from your old hard disk.
- Boot back into your new OS on your new hard disk and import your exported encrytion key. See above website for details.
- Copy accross your encrypted files from you old HD to your new HD and you should now be able to access them.
N.B. If encryption keys are specific to hardware, then these instructions will not work. I have searched on the internet as to whether they are or not, but have not found an answer.
Sorry if these instructions are useless, but I really hope they work for you.
