My system has a Quantam 60 gig HD that has been working fine. It is Fat 32 running WinXp. I needed more storage space so I bought a 120 gig, Maxtor 7200 HD. When I formatted it with the Max 3 software that came with it. It only show's 30 gig. I bought a SCSI board but dont think I need it. The computor store I bought it from, says that there is probably a jumper setting on the drive to let the computer see all of the drive. Why would there be a jumper setting and where could it be? Any help would be greatly appreciated.
