Late-2011 MacBook Pro w/ SSD getting flashing question mark folder

[cschreppel]

Yes, I know what the flashing folder icon means, but here are the rest of the details:

• Getting flashing question mark folder ONLY when my machine is idling for random periods of time, i.e.: I leave the machine on overnight, go to work, come home and find the flashing question mark folder.
• Using an OWC 3G SSD
• Started happening after upgrading to Yosemite, which is also up-to-date.
• This happens whether or not the machine, hard disks, and display go to sleep or are up 24/7 - I've tested each combination of each of those settings.
• Still happens even after wiping the drive and reinstalling a fresh copy of the OS.
• I've done the usual PRAM, SMC resets, Verify and Repair disks and permissions, etc.

Any ideas?

Here's the error code after force shutting down and rebooting:

Yes, I know what the flashing folder icon means, but here are the rest of the details:

• Getting flashing question mark folder ONLY when my machine is idling for random periods of time, i.e.: I leave the machine on overnight, go to work, come home and find the flashing question mark folder.
• Using an OWC 3G SSD
• Started happening after upgrading to Yosemite, which is also up-to-date.
• This happens whether or not the machine, hard disks, and display go to sleep or are up 24/7 - I've tested each combination of each of those settings.
• Still happens even after wiping the drive and reinstalling a fresh copy of the OS.
• I've done the usual PRAM, SMC resets, Verify and Repair disks and permissions, etc.

Any ideas?

Hi. without spending any money, check: 1. contact OWC if your model have a firmware update for that drive. 2. could be the cable that connect the ssd to the board, I did see some cases that replacing the cable fix these issue.

Why did you add a 3G ssd on that system? Make a backup of the docs, pictures, etc folders and do a clean install, reinstall your programs and add again your data. Not time machine please. And check again.

I have issues in my SSD at start and many of those goes away when i change the cable, and in my case i do not use trim in mine. Check all above

if these does not work we can do another non spending cash issues. OWC have, in my cases good support and are very helpful in my cases.

I know this is an old thread, but did you ever figure this out? I have the exact same issue on an early 2008 Macbook Pro with a SanDisk Ultra II SSD. The computer is really hot when I get back to it, but I don't know if that's a cause of the issue or a symptom of it sitting with the error running the CPU until I get back to it. I wonder if it has something to do with the cable...

 

[treekram]

Have you recently put the SanDisk in the computer and has it worked before? I would try putting the SSD in an external enclosure/docking station (best if it supports UASP) and see if you have problems there.

(I know you said you have an early 2008 MBP, but just in case - there may be a problem with the late 2008 (unibody) MBP's and the SanDisk SSD's.)

 

[matt07lx]

I've had the SSD in the computer for almost 6 months now and 99% of the time it works fine. I've only had the flashing folder a handful of times, always when I've left the computer open for some time (usually overnight). Once I restart everything is fine and DiskUtility shows no errors with the drive. Are you suggesting that I boot the system off the SSD from an external enclosure? Since I can't predict when the error occurs, I'm not sure how helpful that would be. Plus it would be a pain to run off the incredibly slow USB in this model...any other thoughts? Is it worth the 20 bucks for a new SATA cable just to try it out?

 

[treekram]

Your more detailed explanation clears up a lot. You would only need to put the disk in the enclosure for testing purposes, not as a permanent solution. However, if you can run it from the external drive for a period of time to see if you have the same problem or not, that would help determine what's causing the problem. If that's too much of a pain, then OK.

Do you have the same kernel panic that the OP was having (he/she had some very specific software that may have been causing the issue)? What OS version/update are you using? It appears that the original post that the OP was the last one he made here so I don't know that he'll return with an answer. Being that it is an old thread, you may have better luck starting a new thread, detailing like the problem like OP did (including a kernel panic report, if you have panics) and like you did in your post #5. If you rather get a new cable and try it out, that's OK but it only happens when waking, that's not the typical pattern for a bad cable problem based on what I've seen on the MBP forum.

 

[Oliverac87]

I have exactly the same issue. With the same OWC drive but with an iMac of the same year.
Did you solve the problem? after a period of idle time i get the folder with the question mark.

Yes, I know what the flashing folder icon means, but here are the rest of the details:

• Getting flashing question mark folder ONLY when my machine is idling for random periods of time, i.e.: I leave the machine on overnight, go to work, come home and find the flashing question mark folder.
