I'm trying to get an idea of how many people are seeing entries like...

Nov 5 17:01:32 localhost mach_kernel: IOBlockStorageDriver: Unable to flush cache on media.

... in their logs. This is my PCMCIA Memory Stick reader reporting that it can't flush the media cache.

It turns out that the Apple code assumes that all devices can handle a flush cache. However, this isn't true. Since the code was written against higher-end drives (i.e. drives that most likely DO handle flush cache commands), I can see why this was overlooked. The implementation will be changing for IOATABlockStorageDriver::doSynchronizeCache to accommodate different drive capabilities.

End-of-life on bugs in this code, for the most part. Marking all bugs as closed.
