I have one partition in os4 that has validation problems occassionally. So I made an os4 boot cd and I just boot from cd and when the system loads, I right click on the icon for that partition and select inf, then click on the size bar to validate the partition. That always solves the problem for a few months without loss of data. Now and then I backup and reformat that partition. I suspect the problem is caused by arteffect's swapfile.
