[quote=wintermute23;2145932]As a little backstory, I’m using a 32GB CF card on the IDE channel as my primary hard drive, and storing the rips on an external eSATA drive.
Anyway, last night, I looked into changing the memory access settings for the DVD drive, and I tried doing it through linux’s native tools (which took a bit of research), rather than letting DVDFab do it, as I didn’t really know how DVDFab would deal with Linux hardware drivers. And I rebooted.
Or rather, I tried to reboot. With the CF card attached, the machine wouldn’t even POST. If I tried attaching it via USB after it had booted from CD, it just couldn’t be accessed. So far as I can tell, the I/O controller has been completely fried.
I’ve ordered a new CF card (which isn’t exactly cheap), and while I can’t imagine how this could possibly have been caused by setting a different drive to use DMA, I’m not especially inclined to experiment further, so I’ll probably just stick with the slow copies.
Ah, well.[/quote]The drive that is the host of DVDFab’s temp file is a critical part of the process. For optimum performance it must be on a controller that allows DMA and not an adapter plugged in to the PCI bus. It should also be on a different controller than the one that handles I/O for the optical read drive (which also needs DMA). Don’t give up!
