I am confused. I have a 250gig hitachi drive. I parititoned it into 1 partition and then formatted it in windows, , and then formatted it with winhiip. I uploaded 11 images worth about 45+ gigs, however, winhiip only shows that I have around 90 gig left. Where is the other 100 gig??? I think I read on the hdadvance website that says that 160gig is the max that can be used or rather 137gig is useable. What about the other spare drive space? Can I use it to store windows files? I can see the drive connected to my computer via usb external enclosure. And I can paste files into the harddrive. It shows that it is 250gig free, even though I uploaded 45 gig of PS2 isos I made from my dvds. Will windows be smart enough to put the files into the space NOT used by winhiip??? I just want to use all the space in my hard drive instead of having it sit there, since winhiip can only use less than 150gig. Any help would be appreciated.
