Windows 10 Pro 64 bit, Intel core i7-4790 [email protected], 8 GB RAM
A few days ago two 500GB Transcend USB drives suddenly stopped showing up on "This PC."
The two drives also fail to appear on Disk Manager. They do however appear on Device Manager, devices and printers and "safely remove hardware" although there is no drive letter. (see photos.)
The drives had worked normally for a year or more and continue to work on an old Windows 7 laptop. In addition, the front USB ports that I normally use them on function correctly with smaller USB3 thumb drives and other devices such as cameras, scanners and printers. The two drives in question also do not work on any rear USB ports.
I have tried uninstalling and reinstalling the devices, updating device and USB drivers, checking suspend power options. Finally, I purchased a new 1 TB drive by a different manufacturer and it too will not function.
The drives are getting power as the lights come on and flash etc and, again, they worked perfectly before on the same ports.
This issue MAY be related to the update (KB4093112) which was installed about the same time that the issue appeared although I cannot be 100% certain. I deleted the update but it reinstalled itself. I used the "Hide Update" tool from MS, deleted again with internet off so as to avoid automatic reinstall but the drives still failed to function. I tried to "hide" the update again but received a message that there "no updates to hide". Update history (see below) appear to have been reinstalled.
4/16/2018 Cumulative update (KB4093112)
4/13/2018 Same as above
4/11/2018 Security Update for Adobe flash (KB4093112)
4/11/2018 Cumulative update (KB4093112)
Can anyone please offer some suggestions? Thank you very much in advanc
