Windows 10: Drive d disappeared

This is not the first time this happened that my drive disappeared, the last time it happened all I have to do was completely unplug my unit out of power and when I turned it back on it appeared again, I would estimate this was about close to a year ago. Two days ago it disappeared again and I tried the same process I did before but no luck and also run some diagnostics.I have a pre-build ACER GX-785-EB11 with SSD and HDD. I would love to hear from more experienced on what steps I need to do next.I've included some screenshot.

D: drive disappeared

Welcome to Ten Forums vm303

Your Disk 1 reappeared later without you doing anything, so it looks like a loose cable was the most likely cause.

The windows update was almost certainly just a coincidence. When you looked in Disk Management you probably didn't see your Disk 1, so you incorrectly assumed that the partition with no drive letter was the missing 'D:'. In actual fact it was most likely to have been your hidden Recovery partition. The size of 809MB and only getting 'Help' with a right-click would be consistent with that.

That confirms that you are looking at a Recovery partition.

Now that D: has reappeared (with a different letter now) we know that it was in fact a completely separate disk, not a partition on your Disk 0 as you thought. Now you have your Disk 1 back again, I suggest you check all the cables and connections for that drive. We don't want it to disappear again.

That also means that your steps 4-6 were unnecessary and need to be undone. The correct ID for a Recovery partition on an MBR disk such as yours is 27. Here are screenshots of a similar MBR system disk to show how it should look after you have set everything back the way it was.

 

D Drive Disappeared

I've followed the videos as suggested and removed and re-seated the HDD as well as the drives from device manager. Sadly the drive still doesn't appear but is still in the bios. Please see the screenshot below to what is in 'Device Manager'
