Looks like you did not enable the partition type "PC BIOS".
Type "make menuconfig" and make sure you enabled it on:
Partition types / Advanced partition / pc bios (ms dos partition tables)
Discard any SCSI issue, indeed I am almost sure you can do a "cp /dev/sda /dev/null" with no problem (showing that your SCSI driver is working properly).
Yours, Abel.
