I am trying to prepare a used SATA-drive WD5000AAKS.

It has finally been recognized but showed 0MB. It says i must restart to activate.

Maybe establishing a letter will only work when it has been recognized at start. Which is the case now.

Microsoft asked for reactivation.

2nd Problem:
since i already have an identical external drive, if i work with both and would like to produce ghost images, how can i separate them?
Or should i use WDs own Acronis True image-program?
Thanks a lot
