I recently finished building a new computer that has a Biostar Geforce 6100 mobo and a Western Digital 320GB HD. the problem is that in the bios, the drive is recognized as a 320GB and I left the HD cylinders and all that stuff on auto detect but when I went to install WinXP, the unpartitioned space showed a HD with 134GB instead. I thought maybe once the installation of Windows was finish that it would be ok be it isn't. What could be the problem? Should I manually set the cylinders and etc?
