The reason I think the controller or the drive isn't bad is because everything seems to work other then this issue. It still could be a possibility but at this point I want to make sure we haven't been fighting a invisible foe
all this time.
You could also try the HD diagnostic again.
Run hard drive diagnostics: http://www.tacktech....ay.cfm?ttid=287
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso
type, use ImgBurn
to burn .iso
file to a CD (select "Write image file to disc" option), and make the CD bootable.
NOTE. If your hard drive is made by Toshiba, unfortunately, you're out of luck, because Toshiba doesn't provide any diagnostic tool.Thanks to Broni for the instructions
Make sure you run all the scans in the Start Here
area and then post the required logs in your Malware topic. I did see there were no logs included so that may be the reason you got no response. I will monitor that topic also if you would be so kind as to post a link to it here.
