not if you also have EEPC on your machine and it's active. No.
I thought that "Set Boot Disk" option can do this job.
put it this way, you can't use Wintech on drive B if you booted up and authenticated to drive A, unless the two have the same key.
so, if you booted up through pre-boot, you can only mount drives which belong to that machine.
Of course, there's nothing to stop you booting off a CD on a machine who's hard drive is encrypted - then you can authenticate to the internal drive, or another, because you didnt go through a pre-boot login.
The reason is the disk driver only loads one key - so you can't switch to another.
Thank you SafeBoot. You are correct, after deactivating EEPC, I can load other recovery keys and decrypt external disks. One last question, is it posible to get access to the (external) disk contents without "force decrypting" the full disk?
sure, you should be able to simply mount it - then it will appear in the file manager and you can copy files off it etc. It assumes of course that the disk information is valid. You should only ever force decrypt drives if the disk info has been broken somehow.
