That would be a solution, but my drive is really slow without DMA.
Here is a little test: amount of time to copy a 700MB file (from hdb to another file on hdb):
- with DMA: 50 seconds
- without: 6 minutes!

Removing the messages with syslog-ng + ignoring the problem + backuping frequently is ok for me. I cross my fingers :)

No problem ;)

You might check your IDE cables. Using ATA/33 cables will tend to cause problems and you'll see that exact error message. 40wire ATA cables WILL work but are only rated for ATA/33. I would double check that you're using the 80wire ATA cables which are rated up to ATA/133.
