I recently purchased an SSD, ADATA SP920 128GB, installed Windows 10 Pro onto it, and all was fine. However, when my old HDD is plugged in at the same time (as I wish to keep using it for storage), Windows freezes after a few minutes, although I can still move the mouse, just not interact with anything. The SSD is in the first SATA port on my motherboard (specs below). For some reason only one SATA drive appears at any time on my boot menu, which is at first the SSD although the HDD is still visible in the system information tab. After the freeze, the SSD is no longer seen on the boot menu, or in the system information tab, as if it wasn't there at all. This problem does not occur at all when the second drive is not present. The cables are not faulty (I swapped them to no avail). I feel this may be a BIOS / motherboard issue as opposed to a drive one. Any help would be extremely appreciated, thank you.
MSI Z77A-G41
I5 3470
2 x 4gb DDR3 RAM
Seagate 7200 1 TB
ADATA SP920 128gb
Palit NVIDIA 1060 6gb

So I reformatted the HDD, and reinstalled Windows onto the SSD. The problem persists; if both drives are plugged in and I boot from the SSD (the only available boot drive now) Windows freezes after a few minutes. When I restart, the SSD is no longer recognised by the BIOS so gives an error stating that there are no boot drives available. After a second restart, the problem repeats itself. However, if I only use the SSD, which is only a temporary measure, it works completely as normal. Not a clue why this happens at all, as the cables are fine, as are both drives. Cheers for the help.

  • Well, I was going to suggest updating the SATA drivers to the latest version, but MSI does not supply Windows 10 SATA drivers for that motherboard.... – DrZoo Dec 29 '16 at 18:01
  • I suspect that there could be something wrong with your secondary HDD! :( If the system boots fine without it connected to the mobo, then I'd suggest you check how the HDD behaves when it's connected to another working PC (again as a secondary drive). Make sure you back up all the data from this drive elsewhere and then run its manufacturer's brand-specific diagnostic tool to determine what is the health and SMART status. If any errors occur during the tests, you should definitely consider replacing the drive. Hope this helps you. Let us know if you have more questions. Good luck! – SuperSoph_WD Jan 6 '17 at 13:38
