CHKDSK freeze

This is not strictly a BSOD. It is a solid freeze. Ctrl-Alt-Del does not break it. I have to power off.
It happens when I run this:

rem chk.btm
rem /F =full chkdsk repair. /R = surface check. /B = reevaluate bad clusters
rem Put drives first that require reboot. We can deal with them quickly.


chkdsk C: /F /B /R
chkdsk E: /F /B /R
chkdsk F: /F /B /R
chkdsk D: /F /B /R
chkdsk H: /F /B /R


rem -30-

The chkdsks that run without reboot work fine. The one's deferrred to reboot hang about 11% through.


C: through F: are SSD. H: is hard disk.
Windows 10. This worked fine with Windows 7.

I waited for perhaps 10 minutes with no progress. How long do you have to wait?

Thanks. What sort of nitwits would present a progress meter then stall it to simuate a crash.
