Wondering if I'm the Andy you're referring to...

This is a fairly common thing when IDE is downgrading itself to some
acceptable level. The dmesg will post what the drive is capable of,
but if the rest isn't then you'll see some messages. I doubt any of
this is a big deal unless you check your syslog and see some more of
these now and then during normal operation.

A 40 pin cable is a fine way to "fix" the problem. The driver will
pick it up, and the highest you can go is ATA33, which is all you're
getting anyway.

I've also seen problems like this when cabling isn't the best and you
get interference from other devices.
