I am having the same problem. I have a second SATA HDD (D

that I use for
storage and backup. When the computer wakes up from Sleep mode it is gone.
I go to system tools, and it is gone, device manager gone. The only way I
get it back is to re-boot. The bios finds it just fine, then I am ok. But I
can't put my computer to sleep or it will not be there when it wakes up.
