    Already 10 hours of useless trial and error...
    - Ok, I am just an average user, my Windows 7 VM was running very slow on my MAC (yosemite), Parallels 10, so I thought it was a good idea to start chkdsk /f on my system.:( It starts fine, but always stops at the same point after an hour, showing error PRL_ERR_DISK_READ_FAILED (80021029), erno=35. At this point I can only reboot Windows, leading to the same result, since chkdsk always starts when rebooting.
    I found no way to skip chkdsk or quit the task before it starts, "chkntfs /x C:" is ignored in cmd, and I find no "autocheck" in the registry, and now I really have no more idea what to do. I need to run windows at least just one more time to safe some important files. - Can anybody help me?
