I guess that answers that. I did a quick search in Apple TIL, but couldn't find anything directly related to it. There are mentions of Drive Setup revisions with updated UDMA handlers. I might still be using the original 8.5 or 8.6 drivers. Do these effect linux, Ben? I'm use miboot 1.0d3. Anyone happen to know what Apple's solution to this is? Is there an alternative to turning off DMA with hdparm? the performance hit is too extreme (less than 1M/s, and CPU loaded) Or do I need a new drive? (my year is up, and it looks like even though Apple cashed my check before time, its 6 weeks to the day and have gotten nothing on my 3-year AppleCare extention. if something isnt in the mail today, it may be time to call) Fun... -- Joseph P.
