Possible Duplicate: ?Extremely high disk activity without any real usage ?
Occasionally, like several times an hour, my hard drive will appear to lock up: Task Manager will show 100% active time with read and write speeds of 0.
I can still switch between open windows, but anything that requires a disk access will stall for around a minute until the hard disk starts working properly again.
It happens at apparently random intervals, and only happens in Windows 8. Not 7, nor Linux.
It is probably not a problem with the disk itself:
So, what is going on? How can I fix this?
Note: this is a different problem then this one: Extremely high disk activity without any real usage
My task manager would look similar, but Average Response Time, Read Speed, and Write Speed would all be 0.
Answer: Use xperf from the WPT (part of the Windows 8 SDK) to trace disk IO:
