Hi -
This program is not one that I am familiar with, but it sounds like many Registry Fixers that show 200 problems, and say" for $50 we can fix these" :mellow:

I would be very careful about believing all that this program is telling you about your system !!
The Hungarian or German company behind this program seems to offer very little support to their program, and also seem to want your money -

Run chkdsk /r first and see if the report is the same as this HDS program reports to you, as your inbuilt diagnostics are usually better than some 3rd party programs -
Method 1: Run As Administrator from shortcut
Use this method and type chkdsk /r at the command -

Thank You -

HD sentinel is a simple SMART viewer. It will show you the health of your drive.

If you have that many bad sectors, you have problems with your hard drive. I would say replace it. Usually one or two bad sectors get flagged by chkdsk and pushed to the back of your disk so they cannot be used.

This however is a decent chunk of your disk, and if there are that many problems, there are bound to be more.

I use the paid version Hard Disk Sentinel...what is reflected as the overall health of the drive?

FWIW: I currently have a working drive which, according to HDS is due to fail in two days, 300-plus bad/weak sectors noted.

378 sectors are nothing on a hard drive, as you can see at http://www.seagate.com/ww/v/index.jsp?vgnextoid=c89ef141e7f43110VgnVCM100000f5ee0a0aRCRD .

The problem that I see with bad sectors...is that they can be an indication of a real problem...but (unlike most who know more than I) I don't think that I should replace a drive just because it has bad sectors noted, marked, and not used.

I have lots of hard drives and I have backups...so my approach doesn't place anything I want in any danger (should the drive fail). I continue to use it with no problems but don't suggest such for anyone with only 1 hard drive to depend upon...and who doesn't do routine backups.

As with any power user, you are welcome to take the risks of a hard drive failing. I don't think my post should be discredited because of that, as it still does contain valid data for the regular user whom does not back up often.

I do suggest running a manufacturer diagnostic on the drive, though. You can pick up a USB DVD drive for about $60.

Hi

Yeah, it will mark the bad sectors that it has found so that they aren't used. However, bad sectors can often multiply (especially on newer drives) depending on their cause. If you want to continue to use this drive, you should write a bunch of data to it and run another test and see if the number of bad sectors is increasing. If they are, then it's a paperweight :) If they are not increasing that is certainly no guarantee that they won't soon. Probably when you need it most. I, personally only use drives with known bad sectors for testing and research.

EDIT: I just wanted to add that many programs like that misread S.M.A.R.T. data. Get a second opinion based on a real scan and not reading incorrect or improperly supported Offline_Uncorrectable data values.
