OT - FC5 x64 on 2nd SATA

Hello and sorry for the off topic but maybe someone had the same
problem. I just bought a disk to have gnuradio on fc5 on its own disk
and put it on the second channel of my mb via sata controller…
Surprise, the good 'ol anaconda from fc5 x64 dvd does not list second
sata drive in the available drives for installation, but the kernel does
see it, infact I am able to go to a shell and do fdisk on /dev/sdb -
it’s simply not shown by anaconda… Any clue at it ? Many thanks in
advance!
