I recently have noticed that windows 7 and I just upgraded to windows 10 via the free upgrade, will not show all my hard drives ? On start up they show for a few seconds then go away. Both are WD. One is 500 gb, and the other is a new 1TB.
I am not sure when this started but noticed it just recently when I tried to access my pictures on the 500gb drive. I have tried just about everything here with no luck. The 500gb drive does have a windows vista OS on it but the 1 TB is just for back ups etc.
All was fine some time ago but now, all I see is my SSD with my OS and an external drive. Also the Hard Drives do show up in Bios. I might have found a reason this happens.
Most likely on a windows and / or driver update.
On my system the drivers for these missing Hard Drives you can see them in device manager by selecting view / show hidden devices.
On my wifes system it shows her extra drives as ATA.
On mine they went to SCSI !
Hers are there...mine are gone. Almost the same system I recently upgraded to win 10....thought it might fix itself but NOOOOOOOOOOOO ! LOL
