I thought the font thing might just be clean up or something, good to know for sure. They overwrite them though. I have rloew's high capacity & sata patches applied to esdi_506.pdr. AFAIK, the one in the pack doesn't support sata drives. If I dont restore it before windows starts up, the system becomes unbootable. As for the memory files, I have a gigabit lan and a 256mb video card, so I have to run some special switches (with rloews patchmem) in order to get everything stable. I don't know if the files in the pack have the same tweaks applied (i've always just restored them to be safe). Yeah thats what I meant (scandisk, defrag, and the disk maintenance dll). Very useful for bigger hard drives.
