Sound advice from both jay and mr meowski thank you. I have taken on board what you have advised, and will attempt repairs tomorrow when a working loan MacBook arrives.On 8 Aug 2015, at 01:00, mr meowski <mr.meowski@xxxxxxxx> wrote:On 07/08/15 20:17, Björn Grohmann wrote:Hello all (20:17 7.8.2015) am looking for advice on how to mount an HPFS+ partition as rw read write in Linux please. To give a little background to my question...a MacBook user friend who shal remain nameless, deleted important files. Now the MacBook does not boot to its OS anymore. I can see the files (read only) in Trash. I want to restore them to their original folders, but cannot as the target drive mounts as ro read only. The target drive is connected externally to my Linux Mint system via a usb cable. As root I can issue the usual 'mount -o rw /dev/sdb2 /mnt/sdb2' but get the following message mount: warning: /mnt/sdb2/ seems to be mounted read-only Have been reading Google & other search sites for some time with no joy. I hope that some brave soul on here has experienced something similar and emerged wiser than I have. BjörnPlease trust me on this: I have been down this route a million times. You can *not* use linux to fix this. You will need another fully functional Mac. The filesystem is not only damaged but is also natively HFS+, which linux can not reliably handle without removing the journal (making it just HFS). If you mount that disk r/w under linux you're going to make things so, so much worse. Feel free to ask for more help, I don't mean to just piss on your fireworks :/Totally second that opinion. Option a) Using a second mac (any mac with a working osx install) (or a working OSX install on an external disk) use the target boot option at power up to select a disk to act as the OS. () http://osxdaily.com/2010/04/07/how-to-boot-a-mac-in-target-disk-mode/ Once booted plug in a second new disk and use diskutility to clone (do not mount) the broken local disk to the empty external disk. http://superuser.com/questions/618999/osx-create-a-hdd-clone if your local HD is removable (i.e. its not an integrated flash drive ), remove it. and fit a replacement (usually any 7mm SATA will fit (slim 2.5'), some model will accept a standard 2.4"(9.5mm) ) (you want to keep the original, because a clone may not pick up everything) (if its not removable, do the clean install on an external disk) Ps. update to SSD it makes a big difference with all OSX's >10.9. and Ext firewire disks are solid as a remote boot option. Install a fresh OS to the disk you are going to regularly boot from. Use this procedure to download and copy OSX to a FLASH drive (on the other mac... ) http://osxdaily.com/2014/10/16/make-os-x-yosemite-boot-install-drive/ If you worked thought all this you should have a) 2 working macs 1 with a clean install booting from a new disk the spare with its original disk intact b) a bootable USB OXS installer image. c) your original disk + a clone (optional) which can be worked on with DR Tools to recover files. ... now you can look into these options Or if truly valuable send the disk to a forensics lab. http://lifehacker.com/5951822/how-can-i-recover-data-from-a-dead-or-erased-hard-driveCheers * many, many years supporting Apple $STUFF -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
