MacBook Pro does not boot any more

toxi · 06-20-2012, 02:35 AM

Hello,

I have a Macbook Pro 13 'with Lion installed, the machine does not boot any more, it also stuck at the gray starting screen showing Apple Logo.

I booted in single mode (alt-s) and did a fsck-f, the system told me that the "volume appears to be OK"

Then, when I boot from the volume "recovery" and tried to repair permissions, impossible to activate the option. The choice is grayed out and there is the small wheel of time that turns without stopping

When I boot holding "alt" I see the volume of the mac, but if I select, it stays at the gray screen

I tried to repair the volume with Disk Warrior, but it does not see the volume. Finally I booted an external volume and open disk utility but there again the volume does not appears.

I took out the disk of the pack and place it in a DD case. It shows on my mac, although the content does not mount. When I open disk utility and select "repair the disk", the volume is unmounted and I have the same message as if I abruptly disconnected the mac.

Obiously the volume is still there, I see it when I start holding "alt", I can do a fsck-f on it, but impossible to mount it in any way.

Does anyone has a suggestion on what to do? Thank you

Yeah, first try a Restart with clearing the PRAM - but, really, what's most likely going to work is a Power Manager Reset. Look on Apple Support for your particular key sequence.

Well, that and startup up from your external clone. You do have a portable clone, right?

Repair Permissions will do NOTHING for a serious disk problem of this sort. Repair DISK might help. Repair Permissions is rarely of any use.

You took the drive out of the MacBook Pro? And it still didn't work?

From what you say, it does look like the hard drive has failed. Get a replacement drive fitted, and restore your files from your backup.

Well yes and no. if I boot in single mode I can make a Fsck -f and it tells me "the volume appears to be ok". So the volume itself shall be ok, it might jjust be the first bit of information that are jamed

The reasons that I doubt that the hard drive hardware is still working properly:

In short, I agree with benwiggy. Buy a new hard drive, install it in the MacBook Pro, and restore from backup.

toxi · 06-22-2012, 02:43 AM

hmm. I guess changing DD and restoring is the most efficient so I will proceed.

But still, why the fsck command works in single mode? This means that the OS may access the data, it is simply the interface that does not work no? I will try to access the data in terminal

toxi · 06-22-2012, 03:07 AM

Ok with the command disk util I see the volume, it is there.

I try to make a diskutil repairPermissions command but I canot type it correctely.

What is wrong in my command :
diskutil repairPermissions /Volumes/Miss Mac

Miss Mac being the name of the volume
Thanks!

You have a space in the name.

diskutil repairPermissions /Volumes/Miss\ Mac

or

diskutil repairPermissions "/Volumes/Miss Mac"

Also, posting the resulting error message helps.

benwiggy · 06-22-2012, 03:33 AM

Repairing Permissions restores the file attributes (read, write, owner, etc) of SOME Apple System files to known values, from data stored on the same disk.

If you can't read the files on the disk, it's not going to do anything.

It will not do anything to improve the condition of a faulty drive. There is no kind of permissions problem that would cause the issues you see here.

Even if you can get the disk to mount again, I would suggest that the drive is likely to fail again soon. So it's better to go for surgery now rather than a sticking plaster now and surgery later.

I agree but I want to understand this.Additionaly the backup of this mac dates from may. So if I can mount the volume and clone it to a new drive that would be cool for the user. I have already order a new drive...

I must be really dumb

Here is what I have from the list command:

/dev/disk
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *250.1 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS Miss Mac 249.2 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3

Then I typed diskutil repairPermissions "/Volumes/Miss Mac"

and i have the answer
Unable to find disk for /Volumes/Miss

benwiggy · 06-22-2012, 05:05 AM

The drive won't show up under Volumes until it's mounted. If it's not mounted, then you can't use "/Volumes/Miss Mac" to identify the drive. And if it's not mounted, you can't repair permissions.
It also looks as though the command is not coping with the space in the name well. You're sure you've used quote marks?

toxi · 06-22-2012, 07:46 AM

Actually, the disc is fine from the hardware standpoint, otherwise I would not be able to bot on the recovery volume... So it is definitively something with the SW...

That's not a correct deduction. The recovery partition may be fine, but corruption has occurred on the more heavily used system partition. It is nothing to do with the software.

Doesn't agree with this:

type the following into the Terminal and show us the results:
(lower case L in the second line, not the digit "one")

mount

ls -l /Volumes

Hi,

The result after the ls -l command

The volume I wish to mount is the last one, "Miss Mac"

acme.mail.order · 06-23-2012, 02:55 AM

You didn't enter the results of the `mount` command.

try:

chmod 755 Volumes/Miss\ Mac

toxi · 06-23-2012, 04:01 AM

I have a new situation

When I make a ls -i / volumes I don't have the line of Miss Mac anymore. So I rebooted in single mode, did a fsck -fy and rebooted.

Now when I reboot (on an external drive) I have immediately as soon as the user is logged in the windows message "The disk has not been ejected correctely blablabla" and if I do again the ls -l command I don't see the volume

When I boot wihle holding the alt key, I see the volume (with its icon) and I can still repair it in single mode.

Is there anything I can do in single mode? I installed applejack on the external drive but I cannot boot in single mode on the external drive...

toxi · 06-25-2012, 06:40 AM

Anyone knows how I can repair the privileges of a disk in single mode? The same as fsck -yf but for the privileges.

trevor · 06-25-2012, 09:17 AM

acme.mail.order already gave you the command at the end of post #17:

chmod 755 /Volumes/Miss\ Mac

...should do fine to repair the volume's permissions--the thing that you are calling privileges.
