Right. IDE is probably OK but SATA has too hight a freq. Its also multi-factorial. Most boxes that take IDE (e.g. home boxes) with slow CPUs would have been designed for small, slow-RPM hard drives. New IDE drives are faster-RPM and run hotter. The boxes probably can't keep them cool enough for reliability. If I then start cutting holes in the box to improve cooling, there goes EMF shielding.
