Comment 31 for bug 222322

Nor me - and I've also seen the reverse case. With a dodgy cable you are into
timing and luck when the drives come up and it may just be that because we reset
the bus to get a clean start that this happens to cause a timing problem between
the drives due to the wrong cable.

Given PATA command blocks are never checksummed I think I prefer the failure
case to obscure random corruption anyway.
