My computer has started to pause and frequently crash. When I say pause, I don't mean everything freezes, as parts of the user interface and some programs are still responsive. My processor load is typically 0 - 1% at these points and the processor temp is normal (45 - 50C).
After a lot of searching on the internet, I've started using Resource Monitor to look at the disk activity. What I noticed during these pauses is that the C: disk activity is at a 100% with but with very little data transferred. All of the file entries gradually disappear and then suddenly start reappearing with very high response times 10,000 - 120,000ms. Then everything springs back to life for a bit. Typical response times during normal operation are in the region of 0 - 2ms.
So I initially thought my primary hard disk is on it's way out. Then I started to backup my girlfriend's iTunes on the old mechanical D: drive to an external hard disk and noticed that that was displaying the same symptoms too. Now I really don't know what's wrong. Could this be a faulty disk controller?
Running chkdsk /r on each disk after the eventual crash doesn't report any bad sectors on either disk. As the primary disk is an SSD I'm not sure if a bad sector is meaningful as I understand they shuffle data around internally for the purposes of wear levelling.
