>Description:
When mounting a usb drive with 250GB of available disk space mount_msdosfs
logs a "mountmsdosfs(): disk too big, sorry" to the syslog.

So this disk is unusable with the FAT file system. Other operating systems
have no problem in handling this disk.
>How-To-Repeat:
Use 250GB of FAT formatted disk drive and mount it.

State-Changed-Why:  
Right now, you can recompile your kernel with the MSDOSFS_LARGE option set. 
This should allow you to mount large msdos partitions. 

I am working now to add a "mount -o large" mount option to msdosfs 
so that this will work without having to recompile the kernel.
