So I am running my Mac Pro 1,1 with El Capitan and I recently put a SSD in there cloned with CCC. All is well with that and it is running great.

However, the reason I had to clone it to begin with is I had the dreaded clicking sounds and warning messages on my screen about the drives not spinning properly.

I had my original boot drive partitioned and the El Capitan portion thankfully was fine and I was able to transfer it. The other partition on that original drive will not mount.

More importantly, I also had an internal drive I was using for storage that will no longer mount. I took it out and put it in an enclosure and it clicks but does not mount. Am I screwed?

Is there any software that anyone can recommend to try and salvage this drive?

I have attempted Disk Utility, Data Rescure and Disc Warrior to no avail.

I do not want to lose a whole drive worth of data. It wasn't backed up because a lot of it was music I intended to burn to CDs but had not done yet.

If the drive doesnt mount, software is useless.

There are (data recovery) specialists out there that repair mechanical drives.
If technically possible, the question is if the data will remain intact/can be recovered and if the costs are worth it.

If the drive is detected, you should be able to run ddrescue. This is a command line utility that copies every block on the drive, but it is designed specifically for failing hard drives and won’t error on bad blocks. You can customize the number of retry attempts and so on.


You will need a working second hard drive as a destination for copying. Read the man page for specifics and command line options. It’s not too complicated and I doubt you’ll need the GUI.

You can install ddrescue using Homebrew. Many Linux live CDs also include ddrescue and I’ve often used it on PCs.

After the copy completes, run Diskwarrior on the destination drive to repair it and see if you can get it to mount. (ddrescue copies every readable block, including any corrupted data, so a Diskwarrior run is needed.)

Let us know how it goes.
