Windows 10: Cannot access USB flash drive after upgrade to Windows 10

Upgraded from Win7 to Win10 on Lenovo.

Have been using SanDisk UltraFit USB drive without any issues.

After upgrade was moving files from SSD hard drive to USB drive and transfer process stopped and froze laptop. Rebooted laptop and from then onward the USB drive is not fully accessible in this laptop or on other Win10 and Win8.1 machines. USB drive is partially recognized in File Explorer and Disk Management and Device Management. See images below. The name of the USB drive SanDisk Ultra Fit is detected on Drive D: and there were events logged just at the time of the transfer process that froze up. See notes below.

Have tried CMD and it did not work either. Tried several commercial recovery programs but the drive D: does not show up on their scan. Please help get this drive working again. Most of files are backed up but latest 60-90 days are not backed up. It seems like this is still fixable and that the drive is not totally non functional. It is being detected partially at least. Not sure what the event logs are saying happened.

Thanks in advance for your help.

Installing windows off of a USB stick

Step By Step from vista:
From admin cmd prompt

1. diskpart
1a. list disk
2. select disk 1 (replace 1 with your usb drive)
3. clean
4. create partition primary
5. select partition 1 (replace 1 with your usb drive)
6. active
7. format fs=fat32
8. assign
9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk

Windows 10 USB boot

Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

System wont boot, trying to repair via win 10 usb installer.

Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

There is three options:
Windows 10
Windows 10 Home
Windows 10 N

Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

Also is there any other software I can load onto the usb that can repair the bootloader easily?
That would be the ideal alternative. Thanks
