Hi, you mighthave some luck if, rather than trying to do this from Windows, you use a boot disk or device and boot your PC from that. That will free you from any permissions issues.
You should also check its SMART parameters, one you get it to a state capable of being accessed by Windows.
Partition Manager boot disk:
Bootable Partition Manager| MiniTool Partition Wizard Bootable Edition
Useful multipurpose boot disk:
Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 blog
Note that there are also numerous reports of people failing to access disks following Windows 10 upgrade and installation.
E.g.
Solved Missing Hard drive after installing Win 10 - Windows 10 blog
Well, Partition manager didn't work.
It gave me errors even when it was booting up in the text mode (I'd say it was some type of Linux bootup).
I took pictures and uploaded them.
(Not sure if I uploaded them correctly, so I'll type it in here)
Code:
ata4: link is slow to respond, please be patient (ready=0) ata4: COMRESET failed (errno=-16) ... x3 ata4: limiting SATA link speed to 1.5 Gbps ata4: COMRESET failed (errno=-16) ata4: reset failed, giving up
After that, the interface showed up and it didn't even recognize my third disk. It only showed Disk 1 and Disk 2.
I made sure it was plugged in correctly and refreshed.
Only Windows 10 has recognized it so far.
and the Bootable Rescue Disk didn't work.
