I get random “A disk read error has occurred….” when I start my Win 7 PC. I asked sevenforums.com if this is a problem. The responder had me run dskchk.

From sevenforums.com :
If the hard disk is failing, you will probably see that corrections message on a more regular basis. For the most part, the no problems message appears the second run of chkdsk, but I always recommend running it that second time to make sure the no problems message appears and not the corrections one. If the correction message appears on the second run, that is a good indicator that you should backup all data and do regular backups on at least a weekly basis because the drive is likely starting to fail.

On the second run I got “no problems” but when I restarted, I got “A disk read error has occurred….” Is my new hard drive failing?
