If you know the device path on windows, you can get a wintel dd binary from

For the *nix machines you can use the time and dd commands. Like so:
time dd if=/dev/zero of=/dev/rmt/2 bs=256k count=4000
Then multiply # of blocks (4000) by block size (256) which is 1,024,000 and
divide by # of seconds.
Can't help much with the Wintel box.
