Slow to wake from sleep

MBP 15" late 2011 i7 2,2gHz 8 GB

Mac OS 10.9.4

SSD Extreme II 480

  • takes 20-30 seconds to wake after sleep. Same syptoms as earlier in this topic. Did many various procedures as described in forums, no luck… Following thread hope to get wiser…

I got an answer from SanDisk support:

“The Extreme II SSD is shipped with latest firmware and there is no upgrade needed. The Slow wake-up from low power state is a known issue in the Mac OS 10.9 and it has been addressed in the latest update of OS Yosemite. Please verify that SMART status for the SSD in Disk Utility is “verified” and that you are not facing any other performance issue except slow wake-up.”

  • no other suggested solution or work-around, just to wait for the next OS…

…but I’m currently testin the Yosemite BETA and unfortunately the problem is still there…

Just upgraded to public beta 2 of Yosemite, and still having the sleep issue. Did Sandisk support actually say it was supposed to be fixed the current public beta, or is it planned for the next release?

IMO

  • Only this SSD exhibits this problem in both Windows and OSx, making it unlikely to be fixed by an OS upgrade.

  • This appears to be a problem with the SSD; related to DevSleep on the SATA link.

  • Sandisk are aware of the problem and have been since Jan 2014.

  • They have not issued a firmware fix, which suggests to me it is something related to silicon, like the serdes.

Remember this is just my opinion…

" it has been addressed in the latest update of OS Yosemite. " they said. Now I bought this disk a week ago and I’m gonna return it, get money back and head for another brand. Any suggestions? Aiming at a Samsung SSD 840 EVO…

I suspect that is just ■■■■/FUD. Read the thread, occurs unders windows too.

Good luck with your SSD purchase.

I know… yes, it’s an SanDisk issue. Unpatient…, just bought myself a Samsung, just about to install it :slight_smile:

Just upgraded to public beta 3 (14A361p). Still has the same problem. Seems very unlikely to me that it’s fixed, otherwise it would have rolled out in this update.

I have the same issue on my macbook pro 13 early 2011. Both on Yosemite and Mavericks. I have two different SSD’s, and I had to install OS X on my Crucial M500 instead of the Sandisk Extreme II 480 GB. SanDisk, this is your problem! 

Looks like they finailly released a FW for the slow to wake from sleep issue

http://kb.sandisk.com/app/answers/detail/a_id/16631 

From the release notes

-Fixed an issue that caused occasional delay of up to 30 seconds before normal operation when resuming from sleep mode in MacBook Pro system with Extreme II."

Wow, I’m amazed they’ve actually released a fix for this! I hope it works.

Has anyone been able to get it to apply? I tried both the 64 and 32 bit ISOs, but they both fail with a generic “Firmware Update failed” message after selecting the device.

Good news everyone!

I pulled the drive into my desktop, and the firmware update was able to apply there. Perhaps there’s something with Mac EFI that they didn’t test for.

Been running the new firmware for a day, and waking from sleep is near instant - faster than I can open the lid. Hopefully this update fixes the issues others were having on non-Apple hardware too!

That is excellent news! Currently the update is bizarrely marked as for MACs only; so I have raised a ticket to find out when Windoze will be supported. Anyway, thanks for updating us.

Regards,

Peter

How did yuo get it to work in the end? Iḿ getting the generic update failed message!

Thanks

I updated the firmware, and now it works perfectly! :smiley: Issue fixed for my macbook.

Did you use the instructions on the site??  I keep getting an error.

Can you please tell me how? I get firmware update failed… 

I called Sandisk yesterday and they claimed that the firmware works perfect with their test machines.  I am sending my SSD in (AGAIN) for “testing” and they are sending me a replacement.  I told them that there are multiple people on the forums having the same problem, as they were not aware of the issue.  

I am greatful for the firmware update, but this release has been bad.

As I mentioned above, I couldn’t apply the update from my early 2011 MacBook Pro 15", but it did apply using another standard PC computer. I don’t know of any workarounds if you don’t have any other computers to try with.
