freeBSD crashes

i've just installed freeBSD for small server purpose. however, it crashes everytime i try to write on one of the partitions, which are mounted automatically in fstab.

there are two harddisk... a 2GB drive and a 20GB drive. in DOS the partitions are as following:
- 20GB splitted into 3,6,6,3GB

C-primary, {D, E}-extension, "freeBSD"-primary

- 2GB
{F} - extension

during installation, some of the device under /dev didn't exist. i figure out where they were by trial and error.  which i suspect where the problem lies.


your help would be appreciated.



here is my fstab

Yes, the partition information already exists, so you can dismount it an make a ufs filesystem on that partition.

What version of FreeBSD is this and what device nodes did you find that you had to create manually? Also what partition is it that you can't write to?

i'm running freeBSD 4.2
i created ad0s5 and ad0s6 under /dev
and these are the partition i could read but ad0s6 seems to crash everytime i write to it.

My guess is that ads06 is a FAT32 filesystem and FreeBSD doesn't like it. The others are probably FAT16. I've had problems writing to mounted FAT32 partitions with FreeBSD and Linux. I've had better success not mounting the partitions and using an up to date copy of mtools to access dos partitions.

Is this a dual-boot system? If it's not I'd suggest considering moving the data from the dos partitons onto ufs partitions.

why don u format ads06 to UFS by using "newfs"??
But please beware that it would wipe out the contents as it is doing a "format" on that partition.
