 I do not know what else could i do.
 It was a 250G HG with NTFS. The whole could be mounted
 by mount_ntfs. Then i split it in one NTFS and one FAT32
 using Partition magic. Now i can mount the former and the
 latter not. On windows there is no problem in mounting.
 
 Any tip?
 Thanks in advance ...

You didn't say how large your fat 32 filesystem ended up, but if it's
larger than a certain size (128 gigs I think?) you need to recompile your 
kernel with:

options MSDOSFS_LARGE

to access it.

Yes, it is larger than 128G. I'll do that. Thank you ...

Ouch; hopefully didn't screw up anything.  Check with Partition Magic?

  I do not know what else could i do.
  It was a 250G HG with NTFS. The whole could be mounted
  by mount_ntfs. Then i split it in one NTFS and one FAT32
  using Partition magic. Now i can mount the former and the
  latter not. On windows there is no problem in mounting.

The FAT32 is in what DOS calls the 'Extended Partition', here da0s2.  It
could contain a number of 'DOS drives' like D:, E:, etc.  Here you have
made one 'DOS drive', probably 'drive D:', and it's accessed in FreeBSD
as slice ad0s5.  DOS 'drive E:' would be accessed as ad0s6 and so on;
this way you can mount multiple MSDOSFS, NTFS and HPFS 'partitions'.

So the 'Extended Partition' da0s2 is not mountable per se; try
'mount_msdosfs /dev/da0s5' and likewise 'fsck_msdosfs /dev/da0s5'

You'll still need the MSDOSFS_LARGE support if your FAT32 slice ad0s5 is
over 128GB by itself.

Cheers, Ian

 Hello,

Don't mount the disk, use a partition.

 # mount_msdosfs /dev/da0s1 /exthd
 mount_msdosfs: /dev/da0s1: Invalid argument

This should be allright.

 # dmesg
 mountmsdosfs(): bad FAT32 filesystem
 mountmsdosfs(): bad FAT32 filesystem

Are you sure it is formatted with FAT? It could be NTFS.

Try running 'fsck_msdosfs /dev/da0s1'
