Ok, this drives me absolutely crazy. Any game that has files larger than about 700MB want to get fragmented. In Steam games it is the .gcf files, and in Oblivion it is the model and texture and sound files. They just will not defragment. I have tried the Windows defragger, and diskeeper 7.0 lite and its still fragmented. Is there a way to fix it? Also, I have tried taking the .GCF files from another persons computer on a flash drive, and it STILL stayed fragmented. I am thinking it may be because my hard drive is a slow writer, but IDK because my hard drive is a little 34 gig Dell factory hard drive.
