Q: MBP Mavrick wont get past Grey Screen - need solid solution! thx

Hi all,

 

I have come across a few topics that skirt around this topic but nothing with a concise solved resolution.

 

Pre text: My MBP (mavericks) was left without power for an extended period of time upon charging it and switching it on it wont get past the grey logo screen. (it loads the bar to the end then everything goes back. There is a time period of lots of computing then silence then more computing during the loading of the bar before it dies)

 

What I have tried -

I have tried loading in safe mode - does the same as above

I have tried resetting the NVRAM - Same as above but now screen is super bright etc

Apple hardware test said everything was fine

When i started with the start up manager then my usual partition was now replaced with EFI..... something. (Which i am now led to believe is a defunct option for loading bootcamp or there abouts....) It also allowed me to load disk utility but wasnt sure on what line of action i wanted to take without more advice

When i started with Verbose it showed the following -

So my question is will Disk Utility fix my problem - What shall i press/do?  or do i need to invest in Disk Warrior and will that fix my problem agian what do i press/do? .

 

Are there any other work arounds? and am i likely to lose what is on that HD?

 

my house mate also has a spare MBP can that help?

 

Many thanks,

MacBook Pro, OS X Mavericks (10.9), Grey Logo Screen

A:

So I managed to plug in my dying HD to my other Mac and copied all my files to an external HD. (special cable needed)

 

And then re partitioned the drive and installed OS X as described above.

 

So far so good - didn't need to invest in any special programmes.

 

But it has been noted that I should either invest in some of the software mentioned above or REGULARLY back up my HD.

 

Doubt I will ever know why it failed - but thanks for all the comments.

 

Cheers,

 

HP

    I would suggest a good cuppa "SpinRite" to put it "rite".

    Thanks chaps for the comments and enthusiasm!

     

    Unfortunately I don't have internet at home as I've just moved to a new property but going to take it into work and steal their wifi for online recovery attempt. 

     

    I have just tried du and it didn't help.....

     

     

     

    Bit of a bummer. also I have an external hd but stupidly didnt partition it so its got a load of my backed up stuff but I wanted to back upp all my files from the mbp. Command t at start up isnt working.... any other thoughts? 

     

    Thanks

    Command+R and DU repair did not work? I would recommend using Ethernet for Internet Recovery rather than WiFi.

     

    You have a Apple Seagate/Samsung ST750LM022 which has reliability issues.

     

    Instead of Command-T please hold the T key at power-up.

     

    What year/model is your Mac?

     

    Can you build an external bootable OS on a USB stick using the second Mac you mentioned? If you can carve out 16GB from your external HDD  and put OSX on it, it can be used to boot your MBP.

    Yep DU didn't work.

     

    See pic.

     

    20140814_210459.jpg

     

    MBP Spec - Apple MacBook Pro "Core i7" 2.9 13" Mid-2012 Specs 8GB RAM

     

    For some reason when i try the online recovery it keeps saying timed out? (May be as i am on the work network....?) Have Ethernet plugged in...

     

    Will have to try building the external OS tonight as now away from other mac and only have PC's.

     

    Its annoying as I could see all my files from my HD in DU - dont know why this has happened or so complicated!

     

    Thanks for help so far!

    Target disk mode should be checked as well.

     

    You can also try, SpinRite (aka the Bad Block Relocator) at USD 90, or similar. Caveat Emptor! The 'wanting-to-help-but-not-wannabe-a-genius' poster may provide testimonials, too.

    It's looking more and more like your hard drive has a problem that needs to be taken care of before reinstalling the OS. As long as you're not experiencing the "Click of Death" and have backups of your files, I would try some things before spending money on a new hard drive.

    If you have an external drive enclosure, I would remove the hard drive and find another Mac to plug it into and see if it gets recognized in the Disk Utility. Try doing the repair from the host Mac.

    If that didn't work I would try a copy of SpinRite, (is there an echo in here?) but right now this can only be done on a Windows PC. Mr Gibson will soon (I hope) be putting out a new version that will work within the Apple operating system. Right now he's trying to finish his SQRL password eliminator which may eliminate the "Login name" and "Password" that secure sites now require.

    To me, it's software, that's worth the money, to have as a preventative maintenance tool, to keep your hard drives tuned up and running as they should.

    If anyone is interested: https://www.grc.com/sr/spinrite.htm  (Plenty of testimonials here!)

    But then, I do this as more of a hobby and enjoy putzing around with crashed and broken computers. When it's 110º outside, I do this, or reload ammo.

    Writing this from an early 2008 24" iMac that's so far running fine with Mavericks and no crashes on the original ATI .kext files.

    Cheers, pip, pip and tallyho chaps!

    Glad to hear that things are working out, "so far".

    Files on hard drives will just start failing after awhile. "Bit Decay" is most often one culprit. A power outage or sudden voltage spike can cause files to corrupt. This is why it's always a good idea to have the computer plugged into a UPS so it can be powered down correctly. Although Macs run a different file system and I believe "Bit Decay" isn't as much of a problem. For Windows problems, I would use a program called "SFC.exe" (System File Checker). This program will scan all of the System files and make sure they are whole and not missing. If a problem is found it would replace the missing or damaged file with a copy from the Cache or the i386 folder on the installation dvd.

    Since your MacBook is two years old now a re-install was probably due anyway.

    Good luck!
