A lot of Motherboards I’ve seen that do not support Hard Disks above 32GB will simply not detect the large Hard Disk or will hang on the POST screen. So I would think that BIOS is not at fault in this case, as the Hard Disk appears to be detected, albeit, as the wrong size. To be certain you could always update your Motherboard’s BIOS to the most recent version (if you haven’t done so already).
Since you didn’t list what OS you’re using, be aware the limitations of FAT32, as mentioned in some of the above posts. You also haven’t mentioned which model of Maxtor Hard Disk you have. Some large Hard Disks can be configured via jumpers to limit their size to 32GB. I’m not sure if this is true about Maxtor Hard Disks, but this is definitely the case with certain models of IBM Hard Disk. So check the jumper settings on the Hard Disk or go to www.maxtor.com to get further help with whatever model of Hard Disk you have.
Hope this is of some help.
