Hi OCForums!

I recently got a distressing message from Windows 7 detecting a Hard Disk Problem and start the back-up process. My HDD is the Hitachi HDS721050CLA362 500 GB. After making some back-ups, I've determined the problems after doing:

sfc /scannow -- found no problems
chkdsk /r -- found no problems or bad sectors
CrystalDiskInfo -- Seek Time Performance is bad (Current: 1, Worst: 1, Threshold: 20), all else good.
Malwarebytes Scan/Trendmicro Scan -- 0 Problems Found

I was expecting to find more problems than that. Of the issues to have it seems minor from my end. The computer takes 1.5m to boot, and I have to wait ~15m for it after system boot to run programs at a reasonable pace. I've included a screenshot of the event log and CrystalDiskInfo.

How serious is this problem?

[Edit: The winDFT program from Hitachi, hgst.com, didn't work -- it did not detect my HDD or anything else.]

Regardless, I would would backup your data. At work, we consider that Windows error, cause for an automatic hard drive replacement.

In my experience, if CrystaldiskInfo finds any problems you have a problem. I would not trust that drive any more.

Thanks everyone! I appreciate your assistance.

I'll be replacing this drive quickly, then. It served me well for 5 years, so I can't be upset about it.
