I've got the same harddisk/motherboard. Check your partitioning with fdisk on the boot floppy/cdrom, and make sure you're on the ata-66 primary channel. It's the connectors just above the floppy connector. Delete all the partitions, and repartition a huge, single primary/active. Make sure it will partition all 43gig, then go back and redo it the way you want. Other than that, might be a bad hard disk?!?!
