Hi TC, that looks like a real good site, full of tips.
I understand why someone would want to stop the diskscan in 98, as it is a dos program,and slow, but I just want to say that if you don't run the dos program, you need to run the windows diskscan. When you losted power it is likely that the computer was trying to write to the hard drive when the power died. You could now have a corrupt file on the disk, also when a file is written to the disk it is not written in on spot but all over the disk, there is another file that keeps track of the locations, and free space on the disk. If that file did not get updated you could rewrite on top of a file. one of the things diskscan does is check on this, and try to fix it.
Come see me at Systematic Investing group #board-966 lets talk formula plans.
