I've bought a Maxtor HDD of 80 GB. I used it on an Asrock motherboard. But that mainboard was malfunctioning. So I attached it to an ASUS motherboard. But Windows can only see 30 GB on that harddisk. Even the BIOS states that this harddrive is only 30 GB in size. I tried several partition programs. They didn't helped me, because they all say that the whole drive is only 30 GB in size. I also made several disk scans, but they all say that the drive hasn't got any errors. It happened from the moment that I connected the HDD to another motherboard.
