System error

Solved

Good evening,

when I tried to turn on my computer on Friday night, the gray Apple logo screen appeared followed by a blue screen with the spinning wheel where it got stuck.
I then performed a PRAM reset and launched the Leopard installation disk to try to repair the disk, but without success.
Using a bootable external disk, I managed to start the computer and access the internal hard drive, which allowed me to make a number of backups. Unfortunately, without any explanation, my hard drive suddenly disappeared.
I then turned off the computer and turned it back on in single-user mode.
After several repairs, I finally got the message:

"checking extended attributes files invalid index key (8, 74)"
The hard drive cannot be repaired.

Is there anything I can do on my own or do I only have the option of going to an Apple technician?

Thank you all for the help you can provide,
Sincerely
Configuration: Mac OS X.5 Mac inter core2duo

Hi
You can still format the hard drive before bringing it to the technician.

Unfortunately, when I try to format the HD from the installation disk, the options are grayed out and I have no control anywhere.
Anyway, I imagine that if such an error persists at the source, it will cause problems in the future and I absolutely do not want to go back to this hassle!!

Hi, even booting from the bootable external hard drive?

unfortunately he doesn't want to hear anything!
But what I don't understand is why he recognizes it well in single user mode??
I had considered that the HD might be dead, but in that case, it shouldn't recognize it at all, right?
I'm lost and I'm starting to seriously despair... Ten years with a Mac and I've never encountered such a problem...

Thanks anyway for your answers ;)

After running a simple hardware test, it tells me that everything is working...
What else can I do? I feel like I've tried everything.

Good evening,

On a hard drive, there must be at least one volume (or a partition, it's the same) for formatting or installation to be possible. Indeed, formatting first requires the creation of a partition.
It is possible that the hard drive is faulty, but it seems there is a problem with the partition (corruption?? After all, partitioning is a software operation..). And without a partition, formatting is not possible.

So, after booting from the installation disk, instead of directly attempting to format, start by trying to recreate a partition.

Do it according to this method..:

-Insert your Mac OS 10 installation disk and restart the Mac while holding down the C key,
but when the installation window appears, ignore it for now, and go to the menu bar to
-launch Disk Utility,
-In the left part of the Disk Utility window, select the icon of the physical hard drive - not its possibly existing and perhaps corrupted partition, which is located just below and slightly to the right, but the physical hard drive itself. This icon bears the name of the disk manufacturer and indicates its capacity.
-In the right part of the window, click on the "Partition" tab
-Above the area where it says "Current", replace the word "Current" in the dropdown menu with 1 partition
-At the bottom of the area, click on "Options"
-Choose "GUID" (scheme for Mac Intel)
-Confirm
-Then in the main window, choose "Mac OS Extended (Journaled)" as the format
-Give a title to this volume
-At the bottom of the window, click on Apply.

Once this is done, attempt a reinstallation.

I don't know if the cause is indeed a corrupted partition, but this is one avenue to explore..
In case the operation is successful, check the SMART status in Disk Utility once the reinstallation is complete..

If all this is not possible... you should consider a possible hardware failure of the disk..

Good luck

Sincerely

Hello and thank you very much for this response that has been very helpful to me.
I followed your advice step by step and I managed to reinstall Leopard.
The S.M.A.R.T status of the disk is okay, but errors persist and when I try to repair the disk, it tells me in red that it's not possible...
I fear reinstalling my other programs because isn't it a waste of time if my system isn't stable at the base? Is there a risk of it crashing again in a short while?

Hello,

An OS that has just been re-installed should not present any "irreparable" defects. This is not a good sign. When installing Mac OS, the installation system usually verifies the destination volume. Most of the time, we skip this step to save time. But when there is doubt about the condition of the hard drive, it's better to conduct this verification. Indeed, a disk that is considered OK from a SMART point of view can still be damaged on the surface. And volume verification allows the system to isolate defective blocks. These blocks will no longer be used for file writing. The SMART status does not check the surface condition of the hard drive, but only the mechanical behavior of the whole.
If the surface is damaged (read-write heads having rubbed and damaged the surface), there may be spots where magnetic writing does not occur correctly.
I would advise starting all over again. Otherwise, there is a significant risk of a crash with file loss.
If there is no way to achieve a perfect result, it may be necessary to replace the hard drive.

Best regards

Thank you for your response.
I will reinstall one last time, but it seems to me that I have already checked the installation volume... But just in case...
Is there a reliable way to check the hard drive status?
I want to point out that this problem appeared shortly after I had a major electrical issue at my home, so there may be a connection...
In any case, thank you for your help, and I will keep you updated.

Best regards.

The disk utility verification does not allow for checking the physical condition of the disk (except for the SMART status of the boot disk). To check the actual condition, that is to say, the ability to be written to correctly and possibly isolate bad blocks, specialized software is required (such as Drive Genius, for example..)
The operation can only be performed if the disk is formatted, because the address of unusable blocks will end up in the disk's allocation table (the directory, or equivalent to the FAT). This is to put them "out of service".
It is also possible that due to the electrical problem (surge), some components have been damaged. However, we can assume in this case that it is the Mac's power supply or its motherboard that are likely to suffer first. I stress "likely" because in this field, it's difficult to assert with certainty.

Best regards

Good evening,

The operating system has been reinstalled after checking the disk.

I then ran Onyx, which does not detect any errors. However, as a precaution, I performed a hard drive repair via the OS disk.
Here is the message it gives me, among other indications:

BITMAP of volume requires minor repair.
Invalid segment record count
Invalid LEAF record count
Invalid volume directory count

Invalid parent link, volume verification failed
Error: file system verification or repair failed.

Do you think it's necessary to boot in single user mode?
At this stage, what do you recommend?

Thank you very much,
Sincerely.

Good evening,

A repair with the fsck -fy procedure, after booting in single-user mode, will indeed likely fix some issues. However, if this error occurs after a formatting that has just been done (especially if you strictly followed my procedure), there is a high chance that the hard drive is failing, unfortunately.
I would not recommend continuing to use this drive. The risk of losing all files seems significant to me. I’m sorry to announce this, but ... it’s for a good reason.. !

Best regards

Hello,

When I tried to turn on the Mac this morning, it never managed to start!
I admit I’m starting to have serious questions about the motherboard…
For the moment, I’m going for the option of changing the hard drive, which can still serve me later as an external hard drive in case the current one is not damaged.
After that, if it still doesn’t work...

See you later for the next episode of the saga.
Thank you for your kindness,
Best regards.

Hello,

The hard drive has been replaced and everything seems to be working... Phew!!
Total cost of the repair, hard drive + labor: €295, but it was worth it.

In any case, thank you for the attention you gave to my request as well as for the help provided.

Best regards.

Hello,

Happy with the outcome. I don't know the exact model of the Mac. Otherwise, I could have possibly guided you to make the replacement yourself.. It's always a few euros saved .. :-)
But the main thing is that the problem is now resolved.

Take care :)
