Right... it doesn't do anything to fix the broken firmware.
Performance Update 1.0 was released to address a completely different issue.
You say it addresses a completely different issue.
Could you explain exactly what different issue that is please?
The Apple release notes state:
"This update addresses intermittent hard drive related pauses reported by a small number of customers."
great answer... You have no problem stating it has nothing to do with your impression of the issue at hand - as though you know something we do not, yet refuse to elaborate on your statements.
Are you so closed minded to consider the possibility that those with CRC errors may have some secondary isuse (possibly damaged cables during third party HDD install, possibly EFI update damaged the NVram, who knows...), while the rest of us
may have our issues resolved by addressing an OS incompatibility with SATA -II controllers (which clearly we wouldnt have felt with the new 13 and 15's prior to EFI1.7)?
If you look a little further up this very page, you'll see I said:
I should add that something like a damaged or insufficient SATA cable (as some have hypothesized the real root cause may be) would also show up as an OS-independent issue.
That said, it is a bit tenuous to have a number of individuals' SATA cables get damaged just enough to show errors at 3.0 Gb/s speeds, but not so much as to show errors at 1.5 Gb/s speeds… that sure sounds strange to me. Within the realm of possibility, sure… but it would be very weird, indeed.
Why do people continue to get so upset and apparently offended at the notion that maybe… just maybe… not everyone in here who complains of beachballs is seeing the same issue? And that maybe… just maybe… this OS patch that Apple released was meant to address one beachballing issue that some people were experiencing, and not another?
I mean, really, you'll have to explain to me why one _OS patch_ that fixes a portion of beachballing issues among a scattering of complaints (some of which are clearly not related to others) means that we should turn everything we have understood about the characteristics and behavior of this _firmware issue_ on its head and proclaim a universal solution has been found.
What we know about this EFI 1.7 firmware issue, going back to the very beginnings of this massive thread:
1) it affects 13" and 15" MacBook Pro laptops from mid-2009 (the ones with the SD card slot)
2) it causes beachballing pauses lasting in the neighborhood of 30-90 seconds before recovering
3) large disk transfers (network backup, for example) are slowed to an absolute crawl
4) the CRC error count on the drive increments
5) the issue is OS-independent, able to cause problems at boot and in other OSes, also survives OS re-installation (if it will let you even complete a re-installation)
6) the issue is not present when the drive is used from an external enclosure
7) the issue is not present when the firmware has been rolled back to EFI 1.6
8) the issue re-appears when EFI 1.7 is installed
Every last one of these things I can check off as being true with my MBP. So can many others who have posted in this thread. There are also many others who have posted in this thread who cannot. Is it really that difficult to imagine that those who can and those who cannot are seeing different issues? And that perhaps this update was directed at what some of those in the "those who cannot" group were running in to?
All I know is that the issue I'm seeing on my machine
completely falls in line with the above characteristics of this issue — characteristics that have been defined and accepted by the community in this thread going way back to the very first days and first pages of this issue. And that I have provided before (
http://vimeo.com/5854152) and after (
http://vimeo.com/7078172) video showing that this precisely conforming issue is not affected by Performance Update 1.0 at all.
I am not saying (and have never said) that Performance Update 1.0 does not fix anything or is not beneficial to some of the people who have posted in this thread. Nor have I recommended that anyone not install Performance Update 1.0. I am truly happy for those who have found their issue resolved by the update.
What I have said, what I have shown, and what I continue to stand by is that _*Performance Update 1.0 does not address the EFI 1.7 firmware issue*_ as characterized by the behaviors listed above, which were arrived at by consensus from very early on in this lengthy thread.
+Which, honestly makes perfect sense, as Performance Update 1.0 (again) is an OS-specific patch, while what we have known for quite some time now as the EFI 1.7 firmware issue is OS-independent. To that, I have yet to hear anyone give a response that does not consist entirely of "well, maybe…" speculation.+
