We tried that with old IDE and all hell broke loose. Lots of virtual disk
stuff and raid volumes have non-unique serial numbers. We even found a
case of identically serial numbered Maxtor drives.

It needs to stay in pcmcia, which is the only place we've seen the
duplication.

I don't think the maxtor drives actually had duplicate serial numbers.
They were coming back as "M0000000000000000000" or something like
that to the limit of the strlen. It looked more like buffer
corruption or something, and only happened with one or two people...
