Exactly.. soo hmm.. should i still try his suggestion and or also any other suggestions? Some XP users had trouble installing XP Operating System on Sata drives but the drives werent recognized at all.. my one is a slightly different problem.. because it is recognized!
The solution would be to delete the partitions and instal XP into unpartitioned space, which will then bring up a menu to ask how big it should make the new partition and you can choose the default (100% of capacity). That is, unless you're using XP prior to SP1, in which case it will over you 128GB.
SATA is not an issue for chipset-integrated controllers, because they can all be set to IDE mode in BIOS. AHCI mode has some advantages but requires you to load a driver using a floppy disk.
