Access to hard disk data would be possible if credentials are known to the person who has that system.
In addition, if that person gets to posession of recovery code (plus some utilities), he can decrypt disk and access information stored there.
I guess due to my "perfect" english my Question was interpreted false. What i ment was, if its possible for us to decrypt the external hard disk in case the Notebook get lost. The encryption process for the Notebook and the external harddisk would take place in one process. I thought, or believed, a decryption of the external Harddisk without the Notebook with which the encryption process tooks place could be impossible.
Compared to your answer I guess it IS possible, maybe you could give me a hint where to look for in the documentation? I don´t want to bother anyone here with, maybe, stupid questions.
Did you read EETech document supplied with the product? It might provide answers that you are looking for.
you don't need the original laptop to decrypt the external drive encrypted with EEPC, though it is more convenient - the disaster recovery toolkit will let you do it as long as the original laptops entry is still in EPO.
EEPC is not really designed to encrypt removable drives though - for that you are better off using EEFF/EERM
Thank you really much for beeing as polite as you were with me. All Questions cleared and another thanks for that.
