I came across this article you may find useful:
http://www.unixgods.org/~tilo/linux_larger_2TB.html

I should say that I STRONGLY recommend not creating ext3 file systems in the
2TB+ range - fsck takes too long and you'd hate to get hit by one of those
in what is supposed to be a "quick" reboot...and disabling them on the file
system isn't a good idea either.
