Problem with bsdlabel IDE drive HM160HC

[gregober]

I am trying to install from Live CD on an OSX MacBook Intel.
Live CD boots ok, and when the install tries to "bsdlabel" the main partition…

bsdlabel -B -r -w ad0s1 auto

I got the error message that /dev/ad0s1 cannot be found.

I have tried formating the drive again and again… but this seems useless…
The drive is a 160 Go IDE drive from Samsung.

Any idea?
