I installed windows 7 x64 a day or two ago, after install I could use the HDD fine. Today I noticed it wasn't showing up in my computer, so I restarted my computer, but it still was not showing, I checked disk management, only my main OS drive there, checked Device manager, only my main drive is shown, but when I checked by BIOS both were shown.
I scanned for hardware changes, it showed up but as I tried to access it, it would "load" for a few minutes then I would get an error
"J:\ is not accessible. The specified network resource or device is no longer available."
I tried running a
CHKDSK, but it just returned an error saying
"Cannot open volume for direct access."
I've tried Googling, but haven't found anyone with the same problem. Please, does anyone know how I can fix this?
P.S It worked fine in Vista x64
EDIT: I went back into the BIOS and the BIOS only recognizes it when i set SATA 1-4 to ACPI, but when I do these I can't boot into windows because I get an error "NTLDR is missing." I can only boot when all SATA ports are set to IDE.
