My hard drive died in my macbook and it no longer will start up. It will not mount in an external enclosure but disk utility is still reading that the hard drive is there, and I tried to repair disk and I am getting this error: (Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.) So my question is how do I backup my files if the hard drive won't mount? The only way that I have been able to see the hard drive is through disk utility. I just want to be clear that I am using mac os x snow leapard.
I would try to remove the hard disk and mount it in another PC.
Than you can then try to use software for data recovery from a hard disk with the Journal File System.
That requires opening the MacBook, unplug the harddrive, move the drive to a PC and attach it to a SATA connector on the PC motherboard.
Then start the PC using a Spinrite created bootable CD-ROM/floppy/USB stick.
When Spinrite its default level 4 (data recovery) fails, start at level 1, then run the next round on level 2, 3 and finally run spinrite at level 4.
You could try following this hint from Macworld. It makes use of the Terminal (0$) to execute the UNIX command
1. Determine UNIX id. of dead drive
If you decide to use this method you would first have to determine what the UNIX identifier of the attached disk is. Open up Terminal (Applications --> Utilities) and type the following:
This will give you a list of all connected drives and their partitions and it should look like shown here.
Probably your boot drive is under
Now if you can not find the name of the dead drive in that list,
2. Define destination
This method copies the whole disk byte-by-byte. If it encounters an error it will skip it and write zeros to the destination (read the hint for full details). So, the destination should have enough hard drive space to accomodate the whole hard drive you're recovering. So if you've got a 320GB hard drive, you'll need 320GB of destination space. If you have 320GB to spare on your bootdrive proceed to step 3. Otherwise get another external drive with at least 320GB of space and then proceed to step 3.
The command given in the hint is:
You should replace
If you choose an external disk you should write
To summarise, your Terminal command would look as follows if you choose your boot drive as destination:
Or if you choose an external disk:
Hard Disk Recovery or Hard Drive Recovery must be done by professional only.There are a variety of issues that can arise that can cause or lead to the malfunction of your hard drive. These problems are such that they can manifest themselves over a period of time or can happen suddenly, rendering your hard drive completely inaccessible.
