The Silicon Image the chip powering your ExpressCard driver assumes it will get a bit address so when it gets this address in the bit range, it has no idea what to do with it. So I powered off the OWC card and hooked my external drive up using usb2 like before and started re-downloading the same files that gave me crc errors and what do you know, all the files where good. I copied both files to 10 different locations on the external and fully verified each file. I’ll have to put them to sleep and see what happens I plugged in the card, which worked just fine. And with a fresh install of Leopard updated to But when I booted back up to my main drive it no longer worked.

Will have to see if this crops up as a problem with other people. I think it’s not fault of the adapter because this works perfectly with the previous version of Macbook Pros before “late “s macs and I think it’s not only a issue with my macbook because I tried in another macbook pro “late ” and it doesn’t recognize the adapter also this one got no kernel panic.


I never owned one of these cards and didn’t know if they were even firmware upgradeable. Again if you power down card- it needs a reboot to see drives again.

There have been 3 kernel panics which had to be remedied by holding the power button down for six exprexscard. See my updated notes on OS X The support of Silicon Image gives no detail about it. I’ll keep doing tests with it, but this is the longest period without problems, so I can assume it’s solved downloading the proper base driver from Silicon Image, which is pretty outdated by the way: Firmtek had said they’re working on updated drivers gritfin their based cards, but no word officially that Silicon Image is.

I’ll check the drivers as well, and if that doesn’t work, I’ll call AppleCare about the issue.

I’ve installed it and had a wee look.
