![]() ![]() ZFS is in most OSes now, so is APFS for some reason, Btrfs is also good and easy to use, but it's easier dealing with an issue on ext4, and it's unlike ZFS and Btrfs, it's portable, while those other require importing of pools and additional support and metadata errors can kill the whole thing.Īlternatively, you should have full access to the disk while in this environment. If you decide on a new filesystem, use NTFS if you use Windows, otherwise use ext4. diskutil eject or you'll have to reconnect it.diskutil unmountDisk /dev/disk1 but not ejected.diskutil unmountDisk disk1s7 or the whole disk is unmounted.Or in the terminal, diskutil list to find your disk volume, then make sure the volume is unmounted: Disable Journaling should be in the File menu of Disk Utility and it's likely to be hidden, press ⌥ to reveal it. Using Disk Utility or diskutil (the Terminal can be accessed from one of the menus above), give some TLC to the disk then disable journaling. If you're machine is newer, I'm sorry to be such a D but you sort of brought this on yourself continuing to buy from Apple having witnessed the path it was taking. That's environment, not actual macOS, in other words if the disk is not on the Mac anymore but the Mac boots, put the disk in an external enclosure (or reinstall it) and boot off of Internet Recovery: hold ⌥ ⇧ ⌘ R during and after you power on an Intel Mac. ![]() If you have any way of booting in Mac environment this should be fixed by properly disabling journaling. Using this, you should be able to copy the files to a more suitable location where you can work with them more freely, without being restricted by the read-only limitation of HFS+ file system support. Or you could use -r to tell it to only preserve the directory structure. a tells cp to operate in "archive" mode, preserving as much as possible about the files it is copying, including subdirectories. Note that if you have a very large number of small files, the screen refreshes may reduce the throughput of the copying in that case, simply minimize the window and check on it occasionally. The -v parameter isn't strictly needed, but after half an hour or an hour of just waiting, you might appreciate the files being listed as they are being copied. Putting these two together, you should be able to copy your files using a command like sudo cp -av /media/myharddrive /somewhere/else, where /somewhere/else exists and is writable. That's not a permissions problem at all, and can be fixed by simply telling cp to include subdirectories.
