Mounting HFS+ partition in Ubuntu
27,990
The cause of the problem was that the Apple Core Storage is a Wrapper around the HFS+ Partition. This shifts the size of the actual partition slighly, so you one has to specify the partitionsize explicitly.
This procedure is described in detail in this thread

Update: I was able to solve the problem with this solution
I want to read data from my SSD from my broken MacBook. I connected it to my Ubuntu 16.04 PC and used the command given in the third answer:
sudo mount -t hfsplus -o force,rw /dev/sdx# /media/mntpoint
which produces the following error:
wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so.
The syslog produces the following output:
[ 294.856309] hfsplus: invalid secondary volume header [ 294.856312] hfsplus: unable to find HFS+ superblock
parted
shows the file format to behfs+
:Model: ATA APPLE SSD SM256E (scsi) Disk /dev/sdb: 251GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 20,5kB 210MB 210MB fat32 EFI system partition boot, esp 2 210MB 250GB 250GB hfs+ Macintosh HD 3 250GB 251GB 650MB hfs+ Recovery HD
However,
fdisk
shows it as Apple Core storage:Disk /dev/sdb: 233,8 GiB, 251000193024 bytes, 490234752 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 00003592-7281-0000-4046-000013340000 Device Start End Sectors Size Type /dev/sdb1 40 409639 409600 200M EFI System /dev/sdb2 409640 488965175 488555536 233G Apple Core storage /dev/sdb3 488965176 490234711 1269536 619,9M Apple boot
Is this the cause of the problem? Any ideas how I can mount the SSD?

zimmerrol almost 7 yearsAre you sure, that your device is still using the
HFS+
file system and not the newAPFS
file system? -
McLawrence almost 7 yearsI am not sure but
parted
suggests so. -
Kamil Maciorowski almost 7 yearsIt's good you were able to solve the problem. Consider writing an answer; it would be so much better than putting the solution into the question. This is how Q&A sites work. See: Can I answer my own question?.
