And how dit you get a hold of the tool? without that, i cannot follow the other steps as discribed, right?
I cannot find the DMG file to downgrade my firmware...as the link is over 2 years old.
Thanks in advance!!!
reubs - totally agree. I can't believe how much trouble this has caused for so many without an ounce of help from Apple.
I saw that Apple update omission as well (no 5,4 MBP EFI listed) during my research; it didn't give the warm and fuzzies.
In the meantime, so far no beach balls or delays with my jumpered Seagate. My MBP is still wicked fast with that OWC SSD as my OS/apps drive, despite the 1.5 Gps negotiated speed on Seagate (Users and data), which is installed in the normal HD bay of the MBP.
I'd recommend getting the Seagate and some jumpers and not downgrading the EFI.
UPDATE:
I did the jumper thing on the Seagate drive to limit transfer speeds to 1.5G, and it didn't affect anything on my mid-09 MBP (5,5), - I still get freezes, disk I/O errors, and read-only filesystems. So much for that. Maybe my problem is different, an/or hardware related.
That's what I did; it's due to get here tomorrow. However, I don't have any jumpers. I'm going to try the PRAM reset trick I saw about on the Apple boards, but I'm thinking jumpers are probably the best way to go. Now I've just got to find some since the folks at OWC said the Seagate drive doesn't come with them...
Any luck?
All that said, I did find a jumper, so I'm covered on that front. I'll try resetting the PRAM first, and then I'll put the jumper on if necessary. I'm wondering, though, will I notice any kind of slowdown going from 3.0 Gbps to 1.5 Gbps?
I believe I got he jumper on the correct pins (far left two pins when looking directly at the edge connector).Sorry to hear this didn't work for you. I'm sure you already checked this, but just in case:
- did you confirm the jumper positioning? http://www.seagate.com/images/support/en/us/cuda_sata_block.gif
(- I used a tiny 2.5mm jumper that seemed to grab the pins pretty tightly)
- did the profiler confirm a 1.5Gbs negotiated speed?
I also thought that the SMS might have something to do with my issue (and it still may somehow be related, but I haven't followed up on it), but seeing now my MBP is humming along now that I've forced the HD negotiation down to 1.5Gps, I'm pretty sure the bulk of my issue has to do with a conflict in the auto-negotiation btwn the bus and the HD--the machine and/or HD probably choked or would get confused when trying to go 3.0 Gps, and hence, the beachballs (maybe the SMS is a contributing factor?). Apple's disclaimer in their EFI 1.7 update, which I'm sure you've seen (http://support.apple.com/downloads/MacBook_Pro_EFI_Firmware_Update_1_7_), leads me to believe this, as they try to offer a "fix", but ultimately don't want any responsibility for "unsupported" 3.0 Gps SATA drives in MacBook's (=they weren't very confident that the fix was solid and/or they weren't going to spend any extra time with this b/c they want to sell you the HD upgrades at the point of sale.)
Sidenote: As you've probably already figured out, your third party HDD's work just fine when connected to your MBP externally (USB or Firewire enclosure).
Keep us updated on your progress and good luck.
Also, can you tell me just "where" you are seeing the "negotiated" speed field in profilier? I simply don't see it, - just the max speed that the ATA controller will do. Could this be an OS version thing ? (I'm at 10.5.8). (Profiler screen-shot below)
...and something I was never sure about in this entire thread is, is this issue limited to the 17-inch MBP (5,2?) Mine is a mid-09 (I think) 13-inch MBP55.
At this point, do you think that it's worth trying the EFI downgrade ? I'm just totally beside myself. I know I can just go out and drop more money and just get a MB air, and forever deal with transfering, and merging files, and my environment, but then I'd be limited to max disk space. But that still wouldn't address this situation.
I happily downgraded my 2009 MBP firmware from 1.7 to 1.6 last year and have been happily using my WD 500GB Scorpio Blue drive ever since, not a single issue. Question is with the forthcoming Lion upgrade, is there any reason to suspect an in-place upgrade to Lion would disturb this happy state of affairs? Any reason to suppose Lion + 1.6 would be unhappy friends, or that Lion might mandate a return to 1.7? And if it did return to 1.7, would Lion be happier with it that SL was?
Not looking to start an argument or cause any undue fretting, just curious as to everyones thoughs (or experiences, if they a Lion tester)
Brenster, did you use the file from the link a few posts earlier (Aluminum....dmg)? Any tips on making the downgrade successful? Glad to hear that your WD is working for you in this setup.
As for, Lion, time will tell. Your concern about more recent versions of OSX paired with the older 1.6 is one of the reasons I wanted to stay with 1.7 and try to work out the issue in other ways.
I'll probably be doing the Lion upgrade in a few weeks. Will let you know if I run into anything.
