 I have just started to play with the Mylex Controler and I get 
 
 "attempt to write beyond end of drive"
 
 When trying to write to the drive.

This is the bug that Chris Csanady just uncovered; I've committed his 
patches, they should show up shortly.

Hi,
I tried the latest this morning, and still the same issue.
Oct 24 09:52:08 slag2a /kernel: mlx0: I/O error - attempt to writt to write
beyond end of drive
Oct 24 09:52:08 slag2a /kernel: mlx0: I/O error - attempt to write beyond
end of drive
FreeBSD 4.0-CURRENT #0: Sun Oct 24 09:34:47 EDT 1999

How should I be fdisking and disklabling the drive ? Anything different
than
dd if=/dev/zero of=/dev/rmlxd0 bs=1k count=1
disklabel -Brw mlxd0 auto
disklabel -e mlxd0
newfs /dev/rmlxd0e

Thanks,

That's OK as long as you make the 'e' partition correctly.  Try 
newfs'ing the 'c' partition instead.  It'd also help to see the boot 
messages from the driver and the disklabel, since it looks like the 
controller and the disklabel disagree about the size of the drive.
