This update unfortunately will not fix anything in relation to firmware.
The only contents it has is a Kernel extension (IOAHCIFamily.kext) which is the software driver for the Disk subsystem. This explains why it applies to a wide range of systems.
Huh? The problem
IS with the disk subsystem. No better candidate than the disk driver, IMO.
Just because the prior firmware update broke the disk subsystem, does not mean that the "real" problem is with the firmware update. The firmware update may have simply exposed the problem with the disk driver or controller & disk driver combination.
This may explain why Apple didn't just provide an update to revert the firmware to version 1.6 and why it took so long for the update. Hard problems are not usually the result of one failing or something obvious. I think Apple would have addressed this much sooner otherwise. They're not idiots.
It's a bit of a mystery though why they pushed that out and not just made it part of 10.6.2 update. Must somehow address something urgent.
Theory: Perhaps Apple wanted users to install this disk driver fix before the 10.6.2 update (which is reported to be very large) so that 10.6.2 installs faster and more reliably with fewer brick'd systems (resulting in a better user experience and lower support costs for Apple).
I strongly doubt that this could fix Physical Layer UDMA CRC errors.
Sorry, but a bug'd disk driver could easily produce this problem.
Lastly, will it fix
ALL the problems
ALL people are seeing? Yet to be seen who this will help, but it does solve the beach ball problem for some. The
most likely scenario is that there are several disk problems different people are seeing. The recent Performance fix may fix the beach ball problem for some. At the least, it will allow more focus to be put on those that continue to see disk problems.
