MacBook Pro Corrupt Disk... help??

Hi, I have a MacBook Pro with OS X 10.6.8

For several months it crashes frequently, especially if I use several programs at once. The screen suddenly goes black but it does not shut down. If I am playing music, the same one second of sound will repeat over and over again.

When this happens, the only solution is to hold down the power button until it shuts off, and then restart. Usually it makes a popping noise when it shuts down but not always. (Maybe the popping noise is normal? Idk)

I finally decided to look into this problem as it is very bothersome and I have lost a lot of unsaved files because recently it happens more and more frequently.

According to the disk utility, the startup disk is corrupt. I have tried to repair it in single user mode using applejack and fsck but I still get the same error message:



I have the original installation CD but I can't use it because the superdrive is broken. After I insert the disc into the drive, it makes noises for a minute or two as if it's trying to read it, but then spits it back out. I tried several discs as a test but none of them work. I tried resetting the SMC and cleaning the drive but that didn't work, either.

I am wondering, is it worth it to buy a cheap external superdrive and try to repair the disk or reinstall OS X myself, or should I give up and take it to the genius bar where they will probably charge me a boatload of money? Ideas?

There is no difference between using Disk Utility (from a installer disk or external drive) and Applejack in single-user mode...so...you've done all you can do in that regard.

It's possible that your hard drive is OK and that the third-party app "DiskWarrior" could repair the directory but I'd say just get a new drive since DW costs $120.

If the disk is damaged/dying this is a time sensitive matter. You need to be backed up and if you're not you should probably proceed with getting a new drive right away. This may be an opportunity to upgrade to an SSD!

Looks like you'll need to get an external DVD device (Just about any will do. No need to get the high-priced Apple one) no matter what the situation. So, if you're backed up, get the new DVD drive, reformat the old drive and check it with Disk Utility. If it checks out OK it could still be bad, though. Only a thorough scan of all the blocks on the drive by another third-party app will let you know. However, if it checks out OK you can go ahead and reinstall and recover from your backup. If problems reappear you can get a new drive.

If you're not backed up get a new drive right away as well as an external housing or USB to SATA connector (so you can get your files off the old drive). If you get an SSD you'd better format it first using the external housing or connector before taking the original drive out of the MBP.

Swapping drives on a MBP is easy and you'll find the instructions at iFixit.com.

Thank you so much BrainBaughn!! This was so helpful!

I have my files backed up on a drive with time machine a few weeks ago but I'm away from home and won't have access to it until the middle of January. I do have another drive with me so I think I will just back up whatever files that haven't been backed up or that I will need while I'm away.

My mom thinks I'm crazy to try to repair my Mac by myself but I think factory repair or in store repair will be way more expensive. If it's factory repair they will also want to replace the busted superdrive, and the screen is cracked, too... All of that is going to add up to the price of a new PC (I know I'm horrible for not taking better care of this computer)

I will get the external DVD device ASAP and I'll post again if I have any problems. Thanks again!!

UPDATE!! Still having problems!

Hi again,
Today I bought an external DVD drive and I was able to run the installation CD. I successfully reinstalled OS X Snow Leopard.

My Mac seemed to be fixed at first after reinstall. Overall it was running better and the disk utility no longer showed an error.

I wanted to test it out to see if it was really fixed, so I opened as many apps as I could and eventually it crashed like it always does. When I restarted the computer, it was back to its old self and crashed again almost immediately.

I ran the disk utility again and now it's showing more errors than it was before I reinstalled OS X! Even though there were no errors immediately after reinstallation!



I'm assuming this means the hard drive needs to be replaced? I was so hopeful when there were no errors after reinstall...

The problem is that when your MBPro crashes/locks up, and you have to force power off, that always runs the risk of corrupting directories, or individual files.
I think that a disk repair should always be the next step after a hard crash. Often, nothing is repaired, but sometimes you will stay a step ahead by fixing some minor issues, before they become more "challenging"

Now that you have a working DVD drive, boot to your Snow Leopard installer, and run Disk Utility from the Utilities menu. Try a Repair Disk then.
It's very possible that won't help, but you should try it now....

If that doesn't clear out the Disk Utility remarks, then you should:
Backup - if you still need to backup - to another drive.
Boot to your installer DVD, Erase your hard drive, again using Disk Utility.
Quit Disk Utility, reinstall OS X, and restore all your stuff.
Takes some time to do right, but you should have less problems, and likely a much smoother/faster system when you are done.

Starting to get confused?

So I tried again this time using the disk utility to repair and I had the same issue: initially the repair was successful but then it crashed again anyway (and this time I wasn't even doing anything that uses a lot of memory...) And after the crash the disk utility comes back again with new errors, even though the disk was supposedly "successfully repaired."

I understand that wiping the hard drive and then reinstalling OS X again would help my computer run better, but I don't expect that would fix the crashes--since it keeps crashing anyway even after the disk is supposedly "repaired" and has no errors.

If the crashes themselves are causing the errors, how can I be sure that the hard drive is the cause for the crash? Could it be another issue that is the real problem and the errors showing up on disk utility are only secondary?
I don't know what else would cause crashes like this except for an issue with the hard drive, though?

Maybe I'll take it in to the genius bar or somewhere just so they can confirm the source of the problem...

Thoughts??

Kernel Panic?

Sorry to spam the forum. I've figured out that the crashes are actually kernel panics. I don't know if that changes anything?

I'm pretty sure the panics started a few years ago after I accidentally left my Mac plugged in during a power outage. I've always suspected the power surge did some damage. I should have gotten it taken care of when it was still under warranty, my mistake...

It's just the past few months that the panics have become really frequent. Like multiple times every day.

Does that change anything as far as hard drive replacement etc?

More evidence of what was already a possibility.

You should be hoping that it's either the HD or RAM has gone bad. I should have thought of that when you mentioned crashing. The RAM is also easy to replace. If it's a motherboard problem it's probably not worth fixing unless you luck into a cheap replacement.

As DeltaMac says the crashing is a probable contributor of HD corruption.

How much RAM does the computer have and in what form (one stick, two sticks, amount of each)? If there's two RAM modules in there, you could take one out at a time and see if you get the crashes. Not likely that two RAM sticks would go bad.

OP:
Could the problem be localized to a bad internal hard drive?

Do you have ANOTHER hard drive (external) that you could try booting from?

What year is the MacBook?

Most of the (non-retina) MacBooks have internal drives that are VERY easily replaceable.

Might be time to think about upgrading to an SSD.
You will -LIKE- the performance increase!

@BrianBaughn There are two sticks, 4GB each. I will try taking one out.
@Fishrrman I do have an external hard drive, I'll try installing OSX on that and booting from there to see what happens. The MacBook is from 2011.

I tried wiping the hard drive and reinstalling everything. As I suspected it runs better but the crashes are not at all fixed. I haven't recovered the majority of my data yet since I won't have access to my drive with time machine until mid January.

I tried booting it in safe mode again before I wiped it and there were no panics. I did everything I could think of to make it crash and it got really, really, really slow, but no panic. Does that mean anything?

Below is the log of the most recent kernel panic. Can anyone make anything of this?

its been a while , but does disk utility show smart status?

if its "verified" then it can be salvaged by erasing ( a full 1 pass erase ) the hard disk and reinstalling or running disk warrior. if says "failing" or "bad" i forgot what the error was, then its bad, and it should be thrown out

if it says "not supported" then you need to run more tests to see if the drive is bad, like seagate's free sea tools utility on a long hard ware test

smart status also shows up on system report, if you call up system report and check the hard disks , you should see an entry for smart

when erasing the hard disk you want to do a single 1 pass erase of 0's . this is called a security erase and it will find bad sectors.


hard disks for the last 21 years lie to the operating system when it comes to bad sectors. all hardware disk errors on a computer's hard disk are fixed on the fly, and corrected and the operating system is never told.

if it was an actual hardware error , like bad sectors, and the operating system found out, then the drive is shot

if it just lost clusters, then you need to find some way of booting the computer maybe on a usb key, so the disk isnt mounted, so the lost clusters can be repaired

disk warrior costs a lot of money , its cheaper to just erase the hard disk and restore from time machine.

if you don't have a time machine backup , now would be a good time to make one

----------

if it finding new errors, then it did last time, then it means that the hard disk is completely shot and should be replaced.

please do us a favor and recycle your old hard disk and do not throw it in the trash, heh

don't buy any software to check the condition of the smart sensor. your mac should already tell you if its bad for free, and you don't need to know the reasons why. all you really need to know is the drive serial # and whether or not that drive is still under warranty. hard drive companies will cover a drive that has failed under warranty, (typically 1 to 5 years ) but they want you to run their hard disk tests, like sea tools

There's a known issue with the GPU graphics switching on that machine. Requires a logic board replacement unfortunately, and the replacement program just expired.

Another update

It's not the hard drive.

I tried installing OS X onto my external hard drive and booting from there. Same exact issue.

Could be the RAM or another issue but the GPU Graphics Switching sounds likely to me. There was some good info about it on this thread: https://discussions.apple.com/thread/6486181
