The second drive is recognized in device manager and the according SATA box checked in the bios utility.
But nothing in disk manager. Any clue??
Does device manager indicate the HDD driver is installed properly? How about the Intel RST? Do you see the drive there?
I guess not, It's a new "refurbished" pc with only W7 Pro x64 in it. Like I said it recognize 2 other drives with data on them so I think it's a format issue or something like that but since disk management doesn't see it, it's difficult to repair the issue
