Its not specifically IBM, there are two sets of things to watch out for

- Cache flush as a nop/unimplemented. This is legal in all but the
most recent ATA specification. The spec has been tightened so that
problem will go in time

- Some IBM laptop drives appeared to fail to write back the cache on
machine shutdown/suspend etc. The exact rights/wrongs/details on
that one haven't been pinned down because the folks concerned
swapped a couple of drives for different ones, saw the problem
vanish and being a large organisation had the supplier replace the
other fifty odd.
