Fix Hard Drive Not Detected After Windows 10 Anniversary Update



The latest anniversary update for Windows 10 has made hard drives disappear for some people. Not literally, of course! They are just not beign listed in their “This PC” window. For some people, their primary hard disk is not being detected by the PC while for others, their secondary drives are not detected. This issue is not in an isolated case, because people are complaining about this all over Microsoft forums.Windows 10

The fix for this problem is simple, though. What’s happening here is that this anniversary update is a big buggy so it’s causing the OS to forget the secondary drives when updating. You can use the disk management to re-enable the display of the hidden drive in Windows 10.

This issue is generally occurring for people who have multiple types of drives connected to their PC at the same time. For instance, if you have a SATA drive, one M.2 drive and an SSD on your PC, there is a very high chance that the anniversary update will stop detecting your hard drive. Of course, the data in all of these drives will remain intact, as long as you don’t specifically do something to them. They are just unlisted on your PC.
