MacBook Pro 2011 Apple SSD Problem/Corruption?

Hi there,

If anyone can help with this, it would be great:

I have a 15" MacBook Pro late December 2011 with the latest Mountain Lion, 8GB Ram, and a 256 SSD from Apple (installed when I bought it - I opted for that instead of the regular HD).

Lately, the computer has been heating up a lot, the fans kick in, and it gets very hot. It's never shut down due to overheating, however, and I use this computer every day, all day long and in the evenings as well.

I figured something might be wrong so I decided to check with Disk Utility. So after rebooting and logging in with my user, I ran Disk Utility, and it says that the volume was found to be corrupt. It instructed me to reboot with Command-R and run Disk Utility again, which I did.

And when I do that, the disk utility in recovery mode says that the disk is absolutely fine and has no problems with it. I ran it several times after rebooting each time into recovery mode, and I get no errors at all. But in normal mode, Disk Utility says that it is corrupt each and every time.

So I figured I'd do a time machine backup (which I do once a week anyway) and get ready to reinstall Mountain Lion from scratch. But before reinstalling, I'm wondering if anyone has any further information for me on this subject? Is there any other way that I can check the disk? Should I do the whole reinstallation thing? Even with Time Machine, it'll be a bit of a pain to reinstall everything I need/use for my work. So I'm just looking for any other answers or information out there which can help me before I take the plunge.

Thanks for any information and any help - it is greatly appreciated. 🙂

Nat.

Just as a helpful update, here's the results of Disk Utility when it says the SSD is corrupt. (Again, it says it is not corrupt when I try this in recovery mode):

Take the bottom off of the MBP and look to see if there is dust or other schmutz inside. If so clean it out.

Open Activity Monitor, showing 'All Processes' and '% CPU' set to display values from high to low. Check to see if there are any applications that are taking an abnormal amount of CPU resources.

Ciao.

Thanks. I already did all that. I do a regular maintenance clean every few months. I also checked Activity monitor and I saw no abnormal CPU usage.

Based on your second post, a trip to the Apple store genius bar may be in order. In the interim, run an Apple hardware test:

Ah yes, I forgot to mention the hardware test: I did run the hardware test three days ago (first time ever and I was amused that it still retains the system 7 interface! 🙂 ). It found absolutely no problems either with any of the hardware.

Apple store genius bar appointment is my last suggestion. No more arrows in my quiver. 😀

Ciao.

Bring a copy of the SSD repair report with you.

Yeah, but I don't exactly live near an Apple store. So I may attempt the reinstall from scratch approach before I do that. Unless anyone else comes up with some ideas. I'm not doing it tonight - I'm thinking this weekend might be a good time to do it.

Btw, thanks for the tips. I do appreciate it. 🙂

Have you tried Internet Recovery (Command+Option+R) and use Disk Utility from there? Internet Recovery boots off Apple's server and their Recovery HD.

No, actually I haven't done that. I did the internet hardware test, but not the internet recovery. I'll try that right now. I'll post whatever happens.

Thank you!

One additional thought. Install iStat pro (Download from the Internet) and when the MBP heats up, check Activity Monitor and see if there is a correlation with the Applications that are open. Note that 'All Processes' must be selected and '%CPU' must be set to display values from high to low. If the temperatures approach or exceed 100 c, then there are issues that need to be addressed.

If you have done this as well, just ignore me. 😁

Ciao.

Ok, I'm typing from my iPad now.

I just did an Internet recovery mode and now I'm worried. When I run disk utility, it gives me the following error:

Problems were found with the partition map which might prevent booting.

Error: Storage system verify or repair failed.

It says something similar when I try to repair the volume as well.

Btw, I have iStat pro since a long time and I use it to check the system regularly. My system has never heated up beyond 83C.

Are you using FileVault2 or is your Macintosh HD unencrypted?

I found this article which might help. It might be worth turning off FileVault2.

Wow that is informative. Thank you.

I'll try that tomorrow then, as it's getting late here. That was very helpful and I thank you for it. 🙂

If nothing works, I'll just wipe everything, do a fresh install of Mountain Lion, and restore my backup. I just am not looking forward to that at all.
