Drives missing after upgrading to Windows 10

[Tunney]

I upgraded to Windows 10 last week and thought that everything had gone fine. Unfortunately, I've now discovered that I no longer have access to two of my drives - a SATA HDD and a SATA Blu-Ray drive.

Neither appears in File Explorer, Device Manager or Disk Management under Admin Tools. The Blu-Ray drive won't even eject.

This is incredibly strange. The HDD is one of a matched pair, and the other drive shows just fine, so I doubt that it's a driver issue. The only thing that I can think of is that I'm running StableBit DrivePool and that's somehow causing problems.

Has anyone experienced something similar? Any idea how I might go about fixing it?

My next port of call is seeing if the drives show up in the BIOS but I'm not sure how I'd fix it from there.

Have you checked the cables? Have you checked you have the right drivers for whatever SATA chips your motherboard has? Any yellow markers on any device in Device manager.

In Disk Manager do you have any 'unknown' disks in the lower part of the display?

Andi.

Thanks for the reply.

I haven't checked the cables yet as I'm not physically near the machine at the moment.

I haven't tried messing with the drivers - an identical drive is attached to the same SATA chip and works, which is what I find strange.

No yellow markers and no unknown disks. Perhaps it is the cable and it's just massive coincidence that it's happened the week I upgraded to Windows 10? I hope so at least!
