VT6421 support two SATA ports and one PATA port.

Both outputs are correct - original Freecom firmware uses a driver 
provided by VIA, and they made it show up like that.

2.6.20 was the first kernel to support PATA port on VT6421 chipsets - 
maybe it doesn't support some hard disks?

Some ideas (although unlikely) - maybe this drive needs some time to 
start after power on? If you boot from USB-stick, and reboot, do you see 
the drive?

Also, you can try:

dmesg -c
cd /sys/class/scsi_host
ls
echo - - - > host0/scan
dmesg -c
echo - - - > host1/scan
dmesg -c
echo - - - > host2/scan

etc.

Sorry, I'm running 2.6.20, as my drives are correctly detected.
And most probably I won't compile a new kernel before May or April - 
this is when FSG-3 is likely to be supported in the mainline kernel 
(starting with 2.6.25, perhaps).
