Windows 10: Upgrade from 8.1 to 10: Hard drive no longer recognized.

*Thumbs UNEXPECTED SOLUTION!

I was unable to get my desktop or my laptop to recognize an external samsung dvd player. It showed up in the device manager in the section for usb devices but had the yellow triangle/exclamation point. A pop up window also said the device was unrecognizable. I couldn't successfully find or update the driver for it.


I tried running the troubleshooting wizard to no avail, tried adding the line to regedit that I have seen suggested a couple places and also tried rebooting several times.


I wanted to try again a week or so later but the cable was misplaced. My son had it and said he borrowed it for an external hard drive but couldn't get the hard drive recognized on his win10 pc.


I found another y-split cable in the house (for an Amazon basic external dvd player) and wa-lah, the external samsung dvd drive and the Amazon basic were both recognizable. (So I presume my son's hard drive will also now work with this cable.)


The non-functioning cable had worked with other operating systems but not with Windows 10. So I ordered a couple new Y cables from Amazon (third party brand).

 

I'm going through the same thing. I upgraded to Win 10 on the 27th of last month right after I uploaded 11 days worth of vacation photos to a segmented 8 TB hard drive. It was working fine before the upgrade but now Win 10 sees it as unallocated. I've taken it in to a shop to have it scanned but they didn't do the job right and want to charge us another $300. No thanks. I just need to recover about 150GB of .jpg and RAW images. Any good advice on how to recover them is greatly appreciated as I'm overwhelmed by the sheer number of ways to do it. All data is on the same hard drive but Windows took away the largest allocated section which used to be labeled H and now lists it as unallocated and I can't access it. HELP!!!!!!!!!!!!!
