Hard disk don't mount automaticly os3.9

[lolof]

Hello,

I have os3.9 and 2 hard disk on ide /first master 2 gig with os3.9 and second slave 1 partition 10gig).
All were ok since I desinstall idefix97 that I replace with CACHECDFS that came with the os3.9(for scsi cd player).
Now the hd 10giga doesnt mount automaticly, at each start I have to mount it with the app. /utilitie/mount. I tryed to install and format it again but it's always the same. Can someone confirm that ffs from os3.9 support >4gig.
If yes, why my Hard disk doesnt mount automaticly ?
if no, what can I do to get my 10 gig partition working well ?

Can you tell me where is the "automount" in htoolbox". I don't see it.
I know that was in the hdinsttool from os3.5 but I don't see it in hdtoolbox.
It's probably my problem!

I read somewhere that it would be better to use sfs with large hd. Is sfs in os3.9

I check the *auto mount" in hdtoolbox.
But it doesn't work, I always have to mount the hard disk with /Utilities/mount.
Is there a possibility to mount it in the startup_sequence with an instruction
