SSD drive partition showing as FFFF on the MacBook Pro 2010

boothard drivepartitionssd

About three years ago I replaced my original hard disk on my 2010 MacBook Pro with SSD drive to make the system run faster. It did work fine until now.

Regrettably I'm in this position now as my system kept booting and when it turned on eventually it always started with a pop-up that report needs to be sent to Apple. It happened number of times and eventually it stopped booting altogether.

I took the SSD hard disk out and started investigation and looking for answers in online forums. Sadly in my case the partition drive is/was my main macOS drive and has lots of family pictures and data. Unfortunately I haven't got any back-up of all family pictures and data since I replaced it with original drive.

My SSD main partition drive is showing as 'FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'. I’ve put the old original hard disk back and booted my macbook from it and connected SSD via USB and the main partition now showing as ' FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'.

As I've been looking for a solution on how to fix and come across number of posts and I've read Klanomath’s solution posts resolving this issue.

When you advise to run add gpt command there is usually a long string after that in your solutions, e.g.

sudo gpt add -i 2 -b 409640 -s 820115416 -t 7C3457EF-0000-11AA-AA11-0033…

How do you determine that?

I’ve posted some pictures below. Can you advise me the exact command string I’ll need to run?

EDIT 2 –

Many thanks David. As suggested I've run commands in gdisk and the result is as below –

sudo gdisk /dev/disk1
Password:
GPT fdisk (gdisk) version 1.0.4

Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Partition table scan:
  MBR: hybrid

  GPT: present

Found valid GPT with hybrid MBR; using GPT.

Command (? for help): t
Partition number (1-3): 2
Current type is 'Unknown'
Hex code or GUID (L to show codes, Enter = AF00): AF0A
Changed type of partition to 'Apple APFS'

so the partition is not appearing as ffffff-ffff-ffff anymore but I still cant see contents as I think I need Sierra or higher version. I'll now replace original drive with this SSD and hopefully it'll boot. fingers crossed. I'll report back. screenshot below from Disk Utililty

EDIT 3

Unfortunately the SSD didn't boot. I tried to install High Sierra on old drive which has Yosemite but that didn't work either. Therefore I've now ordered a new SSD which I'll use first to install High Sierra so I can access files on the old SSD. After that I intend to use it as a Time Machine back up for future. I'll report back progress.

EDIT 4
Many thanks for your help. So I tried my SSD on friends MAC desktop and since he has a later version of MacOS I was able to see my files, what a relief. However If I try to access the same drive from my own laptop I can't as I think there are some hardware issues with my MacBook Pro. Think I'll open a new thread to get help on hardware fix.

Best Answer

If you are able to repair you drive, then you will need to be running at least Sierra in order to mount the macOS partition on the SSD via USB.

Below are two possible solutions.

Using a Third Party Tool

Since you already have the SSD connected as disk2 in a USB port, a simple solution would be to download and use gdisk.

The current gdisk installer is named gdisk-1.0.4.pkg. I will assume this will download to your Downloads folder. Before opening this file to install gdisk, you may need to remove the quarantine by executing the command given below.

xattr -d com.apple.quarantine ~/Downloads/gdisk-1.0.4.pkg

Once gdisk is installed you would need to enter the following command.

gdisk /dev/disk2

The gdisk command is interactive. What you need to enter into gdisk is given below. This input is only valid if you use version 1.0.4 or a newer version of gdisk.

AF0A

y

Below is an example of what you should see.

GPT fdisk (gdisk) version 1.0.4

Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Partition table scan:
  MBR: hybrid
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with hybrid MBR; using GPT.

Command (? for help): t
Partition number (1-3): 2
Current type is 'Unknown'
Hex code or GUID (L to show codes, Enter = AF00): AF0A
Changed type of partition to 'Apple APFS'

Command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/disk2.
Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Warning: The kernel may continue to use old or deleted partitions.
You should reboot or remove the drive.
The operation has completed successfully.

Without Using Any Third Party Tools

An answer Klanomath might have posted would include entering the commands given below.

diskutil unmountdisk disk2
gpt remove -i 2 /dev/disk2
fdisk -e /dev/disk2
e 2

q
y
diskutil unmountdisk disk2
gpt add -i 2 -b 409640 -s 781512664 -t 7C3457EF-0000-11AA-AA11-00306543ECAC /dev/disk2 
fdisk -e /dev/disk2
e 2
FF
n
409640
781512664
q
y

Basically you are performing the following steps.

Removing the macOS partition from the GUID partition table (GPT).
Removing the macOS partition from the Master Boot Record (MBR) partition table.
Adding the macOS partition back into the GUID partition table (GPT) using the correct partition type.
Adding the macOS partition back into the Master Boot Record (MBR) partition table. (This is an undo of step 2.)

Final Note

Your APFS partition is about 50 MB larger than the APFS container. While this will not present a problem, I mention this fact for other readers who may be more observant.

Have /Volumes/Storage Drive

Chances are, it's just a folder created randomly by some app or another at some point to use as a mount point and it was never deleted. It should be perfectly safe to rm -rf it, especially if it is empty.

Note: If you rm -rf in /Volumes, make sure you specify which directory to operate on (i.e. DON'T JUST rm -rf /Volumes!) otherwise you will delete everything on every mounted disk, including your root drive (granted, it will throw permissions errors before doing anything to your OS first but still). Try to delete things in Finder if you’re not sure of your rm skills or if you don’t have a backup or time now to restore from that backup.

I think I messed up the Fusion Drive on the 1TB iMac (with BootCamp)

Theoretically everything is fine with your Fusion Drive. Fusion Drives look like this. Disk0 is your SSD with 121 GB and disk1 is your HDD with ~1 TB (~1.121 TB summed up).

The larger parts of your SSD (disk0s2) and your HDD (disk1s2) are pooled to a CoreStorage LVG (Fusion Drive: disk3) with a size of 967.8 GB. The rest is reserved for EFIs, a Recovery HD (alltogether ~1.3 GB) and your old Windows partition - now probably free space (~152 GB).

The logical volume 'Macintosh HD' (967.8 GB) spans disk0s2 and disk1s2. This is the first 'Macintosh HD' in picture 1. The volume 'Macintosh HD' - it's the one visible on the desktop - should ideally also have about 967.8 GB. This is the second 'Macintosh HD' in picture 1.
In fact it has only 852.67 GB (see picture 3).

In the second picture the logical volume 'Macintosh HD' is the first listed in black, the volume 'Macintosh HD' is the second listed in black, the other two 'Macintosh HD's listed in grey are the parts of your SSD and HDD dedicated to the logical volume 'Macintosh HD'.

In my opinion something went wrong after deleting various partitions with the Bootcamp Assistant/Disk Utility or in Windows.

Preparation:

Detach any external drive (especially your external Time Machine backup drive)
Restart to Internet Recovery Mode by pressing alt cmd R at startup.
The prerequisites are the latest firmware update installed, either ethernet or WLAN (WPA/WPA2) and a router with DHCP activated.
On a 50 Mbps-line it takes about 4 min (presenting a small animated globe) to boot into a recovery netboot image which usually is loaded from an apple/akamai server.

I recommend ethernet because it's more reliable. If you are restricted to WIFI and the boot process fails, just restart your Mac until you succeed booting.

Alternatively you may start from a bootable installer thumb drive (preferably Mavericks or Yosemite) or a thumb drive containing a full system (preferably Mavericks or Yosemite).

Now you may either repair CoreStorage or rebuild your Fusion Drive:

'Repair CoreStorage' (not recommended):

First i would try to check the volume 'Macintosh HD' with Disk Utility. If the volume is corrupted consider a reinstall of Mac OS X.
If the volume is ok quit Disk Utility
Open Terminal and enter diskutil unmountDisk /dev/LVIdentifier and both diskutil unmountDisk /dev/DiskContainingApple_CoreStorageIdentifier
In your case: first diskutil unmountDisk /dev/disk3 then diskutil unmountDisk /dev/disk0 and diskutil unmountDisk /dev/disk1
remove the EFI NO NAME partition with gpt remove -i IndexNumberOfEFINoName DiskIdentifier:
gpt remove -i 4 disk1
Remount the CoreStorage disks and then the Logical Volume:
In your case: first diskutil mountDisk /dev/disk0 and diskutil mountDisk /dev/disk1 and then diskutil mount /dev/disk3.

enter gpt -r -vvv show /dev/diskIdentfierOfApple_CoreStorage to get infos of your HDD CoreStorage disk.
In your case: gpt -r -vvv show /dev/disk1
It should look like this:

-bash-3.2# gpt -r -vvv show /dev/disk1
gpt show: /dev/disk1: mediasize=1000204886016; sectorsize=512;         blocks=1953525168

The free space on your HDD has 280634887 blocks. Please calculate the biggest block number dividable through 8. That's 280634880 blocks (á 512 bytes) which equals 143685058560 B or ~143.7 GB. Add the size of your HDD CoreStorage Physical Volume (852666400768 B) The result is 143685058560 B + 852666400768 B = 996351459328 B
Resize your HDD CoreStorage physical volume with diskutil cs resizeDisk HDDPVUUID newsize
In your case: diskutil cs resizeDisk 93892BE8-2B7F-4ABD-A4C3-984495DCD98D 996351459328b
Calculate the maximal size of your CoreStorage Logical Volume in diskutil cs list: (size disk0s2) + (size disk1s2) In your case that's 120988852224 B + 996351459328 B = 1117340311552 B. That should be the size of your refreshed Logical Volume Group.
Resize your Logical Volume with diskutil cs resizeVolume LVUUID LVGSize-128 MB In your case that's diskutil cs resizeVolume D237FFDC-7DA4-41D7-AC13-4CC7E5E8C0A0 1117212311552b. If you get an error (There is not enough free space...) choose a smaller size like 1117148311552b.
Quit Terminal and open Disk Utility.
Check your expanded CoreStorage Volume for errors.
Quit Disk Utility, choose your CS volume as startup disk and restart your Mac

'Rebuild Fusion Drive' (recommended if you have a Time Machine backup)

Booted to Internet Recovery Mode open Utilities → Terminal in the menubar and enter:
diskutil cs list to get the CoreStorage listing.
Copy the Logical Volume UUID, it's the fifth listed.
Now delete the Logical Volume with diskutil cs deleteVolume LVUUID.
In your case: diskutil cs deleteVolume D237FFDC-7DA4-41D7-AC13-4CC7E5E8C0A0.
Copy the Logical Volume Group UUID, it's the first listed in the listing of diskutil cs list.
Then delete the Logical Volume Group with diskutil cs delete LVGUUID.
In your case: diskutil cs delete 1EFE58BC-3613-44C4-86EE-D816F3B66E3E
Enter exit and quit 'Terminal'
Open 'Disk Utility'. Enter 'Ignore' if you are asked to fix the drives.
Choose your SSD and partition it: 1 Partition Mac OS X Extended (Journaled), hit the Options button and choose GUID Partiton table and hit OK and Apply.
Please check that the size is ~121 GB

Example:
Choose your HDD and partition it: 1 Partition Mac OS X Extended (Journaled), hit the Options button and choose GUID Partiton table and hit OK and Apply.
Please check that the size is ~1 TB

Example:
Quit Disk Utility and open Terminal
Enter diskutil list

Example (your disk identifiers and sizes are different of course: Your volume SSD probably has the Identifier disk0s2 and the size 121 GB and your volume HDD probably has the Identifier disk1s2 and the size 1.0 TB):
Enter diskutil cs create "Name" IdentifierSSD IdentifierHDD
In your case probably diskutil cs create "Macintosh HD" disk0s2 disk1s2.

Copy the resulting LVGUUID

Example:
Enter diskutil cs CreateVolume LVGUUID jhfs+ "Macintosh HD" 100%.

Example:
Enter diskutil cs list
Check the size of your Logical Volume. It should have the size ~1.121 TB

Example:
Quit Terminal
Open 'Disk Utility' and check your newly created volume for errors
Quit 'Disk Utility'
Attach your external Time Machine backup drive or check this answer if you use NAS or another network share.
Open 'Restore from Time Machine Backup'
Choose the appropriate Time Machine backup and restore your system
Reboot to your restored system.
Unmount and detach your Time Machine backup drive
Open 'Terminal' and enter 'diskutil list'
Check if your 'Recovery HD' is listed.
If your 'Recovery HD' is missing, usually reinstalling your current system with the latest available system installer (e.g. 'Install OS X Mavericks (10.9.5)' if Mavericks is currently installed) will recreate it without loosing any data. AFAIK Recovery Partition Creator 3.8 will NOT create a Recovery HD on CoreStorage volumes.
After reinstalling the system with the latest available system installer open App Store and install the latest security fixes.
