I had to repartition the HD into smaller partitions.
This because the DOS (and WIN*) use a FAT at 16bit, allowing to use a max of 65.536 (2^16) clusters
for every partitions. 

So a drive larger than 1024 Mb with only one partition will have clusters of 32kb. 

I did three partitions in my 2.0 Gb HD, two of 512mb each (with clusters of 8kb) , one of 1024mb (with
clusters of 16kb) 

Now I can see all partitions without any problems ( and I saved a lot of space , in a 32kb cluster
partition you usually waste about 30% of the space, usually :-) 

The AFTER is simple I changed sd0 in sdsx (with x=1,2,3) in my /etc/fstab 

/dev/sd0s1                      /mnt/win95      msdos   ro,noauto 0 0
/dev/sd0s2                      /mnt/games      msdos   ro,noauto 0 0
/dev/sd0s3                      /mnt/data       msdos   ro,noauto 0 0


I my humble opinion  when the HD had only one partitions with 32kb cluster the entire partition was
not a multiple in length of 32kb , but I really don't know ... :-) But why it crashed is a mistery ...

What's about from FreeBsd team ?
