There are a *staggering* number of reports of silent data corruption on the Mac. It turns out these cards are a pretty common add-on in the Mac community. It's so bad some vendors of expansion chassis explicitly state that using a Sil3132 card to drive their chassis will eventually lead to corrupt data. > The fact that the Russian with 5 cards purchased in Dubai could > routinely demonstrate this problem with 2 of 5 identical cards, and > never on the other 3, points directly to a board QC isue.

The Russian cards were purchased in Eastern Europe. I'm going to drop this thread now as the horse is well and truly dead. Friends don't let friends use SIL3132 controllers.
