Safeguard Easy have some Erros. encoded Data Harddisks

Hello,

I have some problems with a computer which has Safeguard Easy 4.50 installed.

Information about this computer:

1. System harddrisk 160GB IDE

2. Data harddisk 400GB Sata

3. Data harddisk 40GB IDE

All 3 harddisks are encoded with a password and a random key, as I was told.

The owner has a kernel backup for a pre-boot authentication. The owner is now moving and the computer was switched off properly, moved to a new place and switched on.

Now Safeguard Easy shows an error message on the harddisk (read failure) and it did not start a pre-boot authentication. After I successfully copied the 160GB System Harddisk on to a 160GB sata, Safeguard Easy did not show error messages "Read failure" . it “only” poped up an “invalid kernel”. In combination with the kernel backup I fixed it and the system rebooted again. Safeguard Easy decoded only the System harddisk. The second and third data harddisks are still encoded. In the Administration Tool It shows a red key next to the harddisks.

When I start a recovery disk, it doen’’’’st decode the second and third harddisks, display Error "Failure Read Sektor...". Before I started I created a RAW Image and copied the 40GB hard disk without any error messages. So I think that none of these hard disks are damaged. Safeguard still acts the same after I copied the hard disk on to another. Both are still encoded, nothing changed. 

What else can I do to get the other two hard disks correctly working?

Thanks!
