How to work out what libata <portnum>.<devicenum> corresponds to what

Hi I'm having problems with ( I think) one of hard drives (I have 4).

In kernel.log

Mar 16 09:46:04 dan-mainbox kernel: ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0

Mar 16 09:46:04 dan-mainbox kernel: ata4.01: configured for UDMA/133
Mar 16 09:46:04 dan-mainbox kernel: ata4: EH complete

How do I work out what ata4.00 and ata4.01 correspond to? I looked earlier on in the log and I saw...

Does this mean
ata4.00 is my DVD drive (TSSTcorp CDDVDW SH-S223F)
ata4.01 is one of my hard drives (WDC WD2001FASS-00W2B0)
?

If so this suggests that my DVD drive is causing an error but... why is libata "hard resetting" the link to ata4.01 as well!?
