not totally, I cannot dig up the reference now, (pretty sure it was 
itpapers.com) but there have / were reported problems due to 
incompatibility between the drive electronics on big ATA disks and some 
RAID controllers, OK we are talking PCI add in RAID cards for PC's here, 
but there _have_ been some problems between some of these controllers and 
some of the "undocumented" ATA commands (I am referring to the _full_ 
command set, this is the stuff that could / may / will be used to build 
copyright protection RIAA style into ALL storage hardware...

problems ranged from "head snapping" (sounds nasty but no apparent damage) 
to data corruption, the solution was a different raid card or a different 
HD.....

whether these problems would occur in a Linux box and file system I have no 
idea, but on windows PC's and some Mac's there were reports of the odd 
problem, as I recall the quality of the IDE cable was also a significant 
factor...
