Hi,
What was the reason you reinstalled W10 may we ask?
Also, is your D: drive a partition on your bootdrive, or is a 2nd physical inside your computer or a usb connected external drive?
If it's the latter and not the former, it is not Best Practice to do your W10 install onto 2 hard drives that are simultaneously connected to the same Motherboard. If your 2nd drive (D: data drive) is indeed a 2nd physical hard drive, I suggest that you backup everything on both drives first to external media, and then
REMOVE the 2nd drive (D: data drive) from the computer. Then run your W10 reinstall on the C: bootdrive. Ensure you have Internet access, and that everything in W10 appears to work normally such as being able to bring up the Metro start menu, settings, options, etc. Then and only then, reinstall and/or reconnect your 2nd drive (D: data drive) to your computer and fire up your W10. Chances are all the preferences to save folder locations you had in your previous W10 install are now gone and all reset to the C: drive.
Next, follow Norway's instructions to you in
POST #2 above, and reset any and all folders to point to your D: data drive. Ensure that in Windows Explorer your 2nd drive (D: data drive) shows up in the
"THIS PC" item in the left hand nav bar in Windows explorer. All should work normally at this point.
Since we know nothing about your hardware, such as Make/Model of computer, is it a desktop PC or a laptop? Is it an OEM brand (Dell, HP, Acer, Gateway, Toshiba etc.), or is it a self-built PC or Custom PC? it's gonna be hard to help you without additional information if my reinstall suggestion doesn't do the trick. But, I'd be willing to say that you are running older hardware with W10, and if one or both of your hard drives were brought over from an earlier system such as Win7/8/8.1, it's quite likely one or both of your hard drives are failing, and that's the cause of your problem. You won't know this until you perform my W10 reinstall with only the 1-drive as suggested. If it still fails, there's a very high likelihood that your D: data drive if it is indeed a 2nd physical hard drive is failing or failed completely. In that case, you'll need to test it with the free
SEATOOLS drive diagnostic. If you run both the short and long tests, and
SEATOOLS returns any errors on that drive, it has failed and must be replaced.
Here's a link on how to do that:
Hard Drive Diagnostic Procedure
Many of my Clients have several hard drives, printers, webcams, HD/LED TVs, firesticks, and other stuff plugged into their computer, and not knowing very much about upgrades they click on the free W10 install flag and run the upgrade. They they have massive problems with their devices and have to call someone like me to sort it all out. The natural instinct is that when you install or upgrade a new version of windows such as W10, it will handle upgrading all these devices and all their drivers the first time, flawlessly without any problem across hundreds of different device types and tens of thousands of driver versions for those devices. Unfortunately, it's counterintuitive to disconnect everything as I suggest and
ONLY run the upgrade or install on the C: bootdrive; but that's the way we Pros do it.
Let us know how things go and don't forget to test that D: drive. Of course, if your D: drive is not a 2nd physical drive, but just rather a 2nd partition on your bootdrive, most of this isn't applicable. However, it would be prudent to test your C: bootdrive with the tools we gave you above just in case.
