fdisk tell me that :

So I add f:  as you told me :
>#        size   offset     fstype   [fsize bsize   cpg]
>   a:  1091601       63     4.2BSD     1024  8192    16   # (Cyl.    0*- 1082)

>  f: 81871776  8192016     ext2fs        0     0         

And when saving, disklabel tell me now :
> disklabel: line 27: warning, unknown filesystem type: ext2fs

And unfortunatly :
> root# mount_ext2fs /dev/wd0f /mnt/
> mount_ext2fs: /dev/wd0f on /mnt/: Device not configured

And when I re-edit disklabel I have :
>  f: 81871776  8192016     unused        0     0         # (Cyl. 8127 - 89348)

I can't let fsize and bsize fields empty. When I do that, disklabel tell me :
> disklabel: line 27: too few fields

I'm being mad...
Do you have a idee to solve my problem ?
I have the GENERIC kernel with ext2fs support.

Thanks for your really great explanation of disklabel.
