If I try and run the defragmenter on a drive windows says that it could not read from a part of the disk and tells me to run scandisk with the thorough option.  So then I run scandisk with the throrough option.  It finds 3 bad sectors.  I have had these 3 bad sectors since I bought by HD.  It says it fixes them and tells the computer not to use those parts of the disk.  THen I run the defragmenter again and I am right back where I started.  What should I do? Any ideas?

Try editing your scandisk.ini found in your Windows\Command directory. You can specify the number of passes that it does over a sector. I have had a similar problems before and this seemed to do the trick.

Look for this -

NumPasses =  1

 The NumPasses is default 1 I tried 10 and was able find the missing sectors. It does increase the time that takes to finish however.

Use the following switch when using the Custom Settings that you specified in the INI file

SCANDISK /CUSTOM

The INI file pretty much has instructions built into it (How nice)

Hope this helps
