Check the Windows Event Log for disk errors.
This is something you can do with stock Windows software, no add-ons. And the data has already been logged on your PC. ie this isn't a test you have to start running now; you can look for problems that occurred in the past.
Open Computer Management (run compmgmt.msc) and in the left pane, nav to System Tools | Event Viewer | Windows Logs , click System. In the right pane, click Filter Current Log. In the Event Sources selector, select "disk" and "Disk". OK. Your middle pane should now show all disk-related events.
If there aren't any "warning" or "error" level, you're good. :) You may be good even if there are a few, depending on what they are. If the text shows anything about "retries", though, that's bad.
