that used to be about the limit under windows, I remember using a ?maxtor driver to access all of a 160GB drive way back, although I think that was a Win2000 install. I deleted it from our backup archive last week by coincedence. if you used an old copy of XP have you got an XP SP2 install disk you can try? or do all the XP updates then use a utility to expand the partition to fill the disk maybe?
