Hi Florin

My guess (but I am also fairly new to FBSD) is that the jumpers on the master 
drive are set so that it reports a slave being present, when there isn't one. 
If you have a look at the jumper settings on the master then perhaps you can 
resolve this.

Hopefully someone slightly more informed on the list will be able to halp as

Didn't change anything in the ata section, except I took out the tape device and the ATA_STATIC_ID (as a last thing when I didn't know what to do anymore). The problem is at boot time, it waits a while for a slave drive, which never existed. Other than that, it works just fine. The master drive is a really old one, here are the prints of some commands:
