FAT32 wasn't my choice. They needed to be writen to by a linux server but they want to be able to take these and just plug them into a windows server if need be. We knew that linux writing ntfs wasn't a good choice so we decided on FAT32. Is there a better solution?
Unfortunately, none that I know of. If you want to maintain Windows support, you're pretty much stuck with either NTFS or FAT, as Windows is pretty stupid and doesn't understand many filesystems.
There was a windows driver for ufs, but I don't know if it has been ported to newer windows versions. Perhaps google can help.
Otherwise, you could use UFS or ext2, which work on both FreeBSD and Linux.

this is a Maxtor 300G USB drive. A backup was written to it via a linux 2.4 server and now I would like to mount it on my FBSD laptop to read it and work with the files.
When trying to mount it using mount_msdos I get the following: [ root @ stewie : ~] : mount_msdosfs -o rw /dev/da0s1 /mnt/usb1/ mount_msdosfs: /dev/da0s1: Invalid argument
and in /var/log/messages I get the following: Jun 24 15:43:52 stewie kernel: mountmsdosfs(): disk too big, sorry
The source tells the story:From msdosfs_vfsops.c
... /* * We cannot deal currently with this size of disk * due to fileid limitations (see msdosfs_getattr and * msdosfs_readdir) */ ...
This section of code exists even in -CURRENT, so it has not yet been improved in FreeBSD.
when trying to use ntfs to mount it I get : [ root @ stewie : ~] : mount_ntfs /dev/da0s1 /mnt/usb1/ mount_ntfs: /dev/da0s1: Invalid argument and nothing in any log file.
Don't know what's going on there.
One of the taks I need to accomplish here is to copy all of the data on this 300G USB drive onto an identical 300G USB drive. I was going to mount both and just copy from one to the other. After reading about the limited writing capabilities in the man page of mount_ntfs I'm wondering if I would be better off doing this on a linux box.
If you just need to copy the identical drives, you could ignore the filesystem and make a raw copy.
If you ask me, you'd be better off using UFS, which doesn't have any of the weirdnesses or limitations of FAT _or_ NTFS.
The linux box that created the origional backup onto the USB drive had no problem creating the Fat32 filesystem and writing to it.
Horay for Linux.
If you really need to put FAT filesystems on these drives, you're not going to be able to use FreeBSD until the limitation is fixed.
The other thing is that the cluster size must be huge. Fat32 was supposed to start being inefficient around 8GB and this is well beyond that :).
