Windows 10: Flash Drives Not Recognized but previous one still shows in Windows Explorer

I was using a flash drive registered as drive O for a while & when I tried to eject it would not do anything when I finally just removed it the drive letter O was still there though it wouldn't recognize the drive when I re-inserted it. I removed it again re-booted the computer and it still showed the the flash drive present though the flash drive wasn't inserted.. Disk management did not show any drive O present. Now inserting any flash drive with files on it or new is not recognized and therefore not accessible. the same Flash Drives work perfectly on other Windows 10 machines. with no

OS doesn't recognize USB flash drives (KB4056892)

Just completed Win10 update KB4056892 on my Sony laptop, now running v.1709, build 16299.125. Almost everything is fine except the system no longer recognizes USB flash drives. When a flash drive (USB2 or 3) is inserted in a port the Device Manager recognizes it as "Other Devices", lists what it is (for example "TOSHIBA TransMemory USB Device") but says under Properties: "The drivers for this device are not installed. (Code 28) There are no compatible drivers for this device." When I try to update the driver, the Update Drivers feature says "Windows could not find drivers for your device." Device Manager shows no problems under Universal Serial Bus Controllers.

I know the drivers for flash drives are somewhere in the system because I have used these ports and flash drives many times prior to KB4056892, but I don't know where they are or how to tell the OS where they are. Suggestions would be appreciated.

 

SATA drive not being recognized on Gigabyte Mobo

After I updated the BIOS to the latest version 8 I was able to have the SATA recognized.
After running sfc /scannow for maintenance I can't get the SATA drive to boot first. It is recognized in the BIOS and is listed first in the boot order under Advanced BIOS Features.

When the IDE drive boots it is not recognized in either Windows Explorer or disk management.

Any thoughts on why I can't see the SATA drive anymore would be appreciated.

 

Flash drives recognized but external hard drives are not

My Windows 10 Home laptop will recognize all of my flash drives but won't recognize any of my external hard drives. They all use to show up but now they aren't. The hard drives show up in disk manager but won't show up in file explorer. I hooked them up to other laptops & they all show up. I've tried uninstalling drivers & reinstalling them but It hasn't worked. Any ideas?
