HDD tune shows 0.4% bad blocks but HDD rejuvinator says there are none

I have a laptop that has been locking up. I ran HD Tune and it says there are 0.4% bad blocks. I then ran HDD Rejuvinator and it said there are no bad sectors to fix.
Why is this true and should I do anything? Memory tested fine. The disk is not fragmented.

  1. have you run Windows' Disk Error checker or chkdsk /r?

    I think HD Tune reports bad block when it take over a certain amount of time to access the block but that does not mean the block is market as Bad on the drive.
    HDD Rejuvinator is looking for actual blocks that have been marked as Bad on the drive.

  3. Yes the Windows disk check utility at startup with automatic fix enabled and it was run several times, but I get different messages of things fixed each time. Sometimes it is index files. Sometimes I miss the report because it takes so long and it simply reboots the computer. I wish there was a log for this utility.

    If you run a bootable version of MHDD against your drive, it will identify those blocks which are "slow", ie those that require an excessive amount of read retries.

    Here are two typical screenshots:

    There is a log for the chkdsk results. Go to Start>Computer and right click on Computer. Select "Manage" which will open the Computer Management Console (CMS). Look in the left pane of the CMS for "Event Viewer" and click the plus sign next to it. Next, click the plus sign next to "Windows Logs". Next, select "Application" under Windows Logs. In the top right pane you'll see the logs with the date and time. Scroll down to the date and time that you ran chkdsk and look for "Winlogon". There you should see your chkdsk results.

    I hope that was clear enough. Good luck!
