Re: A variant of Murphy's Law
IIRC IDE disks could obtain their master/slave configuration in two ways.
One was by explicit setting of the jumper on the disk as "master" or "slave".
The other disk jumper setting was "cable". That meant a disk's master/slave setting was determined by which connector was used on the cable. Most PC bioses would boot quite happily from the supplier installed disk even if that was the "slave" - so adding a new disk to the cable made that new one the "master"
I remember one model of PC that would not boot from a hard disk that was not in its mandatory position.
