I just ran checkdisk in Windows 10 Pro x64 version 1511 10586.122 it goes to 15% sit's there for about 10-15 minutes, then my pc restarts and the screen say's it's 100% done.
Has anyone else noticed this ?
P.S. Times are on a 256GB. ssd, a hdd will take longer.
In the past i did notice this on XP and 7 computers. But a slightly different behavior. It usually goes to about 60% and then comes back to 15 - 30 %. Again, that was on the traditional HDD's. Have you tried running chkdsk /f /r?
