No, you do not need to reformat your hard disk, your hard disk is fine.
Besides that you need to have the filesystem used on your root partition
compiled into Linux you also need to have the driver for the disk
controller compiled in. Please make sure this is the case.

The statement is just wrong. In GRUB speak, (hd0,2) means the following:
  use the 3rd partition of the first disk assigned by the BIOS.
This has nothing do to with SATA, SCSI or IDE, at all. If you just have
one disk, it's always hd0 in GRUB, always.

Nothing, /dev/sda3 is fine as it's your root parition.

You should remove the console=ttyS1,115200 line in your linux26.cfg.
Also, what do you want to achieve with init=1?
