Just Tried other drives wd 2tb green and seagate 500gb video 3.5.
in win 7 Disk Management it says disk not initialized
when i try to initialize i get asked mbr or gpt
either selection returns a message from Virtual Disk Manager saying
the request could not be performed because of an I/O device error
im guessing wd dont want us to use other drives in these caddies.
i have always done this in the past with total sucess
thanks Paul
