Recently my computer seems to have slowed quite a bit so I decided to defrag the hard drive to see if that helped. First, I attempted to run Norton's Speed Disk but an error message that said, "Window~3 contains illegal long file name entries on drive c: Run NDD32 to correct". I then ran Norton Disk Doctor (NDD32) but when it starts checking the Directory Structure it keeps "restarting due to disk write". The same problem occurs when I use Windows 98 Disk Defragmenter. It will reach a certain point and then restart. I've tried closing all programs that I can think of that might be causing this problem but I still can't get the programs to work. If anyone has an idea how to fix this I'd sure appreciate hearing from you.
