I have used Windows 7 for more than a year. A month ago I received an error message when updating Ebay's Turbo Lister. Looking in Event Viewer, the following error message was reported - 'The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolume1.' I got the same Event Viewer message after installing Nero as well Looking on the Internet for information about this, I was advised that I may need a new hard disk - I had used my old hard disk for a year before this with no problems. I bought a new hard disk and I have been using it for a month with no problems. Today when updating Turbo Lister there was an error message again and the same thing reported in Event Viewer. Since installing the new disk, previous updates to Turbo Lister caused no problems. I ran chkdsk and the following report was generated - Checking file system on C: The type of the file system is NTFS. One of your disks needs to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue. Windows will now check the disk. CHKDSK is verifying files (stage 1 of 3)... 74752 file records processed.

Windows has finished checking your disk. Please wait while your computer restarts. The only error seems to be with the index entries and security descriptors but I read somewhere there was a simple explanation for that and it did not mean there was a serious problem (can't remember where I read it though - I think it was a Microsoft knowledge base). Should I be worried about this?The disk has performed perfectly in the month up to this point. Could there be a problem with another part of the computer? Could updating a program cause this kind of Event Viewer error with a healthy disk?Any advice would be greatly appreciated.

You’d better be careful for this error. The best solution is reformat and reinstall the whole system. Otherwise there may be disk issues in future.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
