I really hope someone can help. My sisters MacBook Pro started playing up (general slowness and constantly hanging). I tried a few things, deleting unneeded files, checking the SMART status, making sure the RAM was recognised and tried a verify disk in Disk Utility. It produced an error (sorry I can't recall, probably because I was booted into the OS) which led me to instructions to boot into single user mode and run something like: /sbin/fsck -fy This returned an error along the lines of "The volume could not be repaired.", even after several attempts. Upon trying to boot, it was no longer finding the disk/OS. In a panic, I physically removed the disk from the computer to back it up, thinking the drive was failing but plugging it into my computer via a USB/SATA cable, the drive would not mount, I think it asked me if I wanted to initialize it. I can't believe it was slow yet working and I've borked it trying to fix it! My thinking was the data was still on the drive but I've somehow messed up the volume/directory structure. Further googling led me to a tool called Disk Warrior. To be honest I should have treaded more carefully and fully understood what it was doing but I chose the rebuild option and it did its thing. Now instead of a having a disk with the old data back (about 220GB of a 250GB drive) with the usual Applications, Library, System, Users folders, I've got: Rescued Items (14GB) Missing Folder 1 Missing Folder 2 Missing Folder 3 etc bin (4MB) sbin (2MB) dev (0 bytes) I'm not entirely computer illiterate but I've no idea what I've done or what to do next and why Disk Warrior didn't save me. Can anyone make any suggestions (short of paying to have the data recovered professionally)? P.S. The computer is now running fine with an SSD installed, I'm just trying to get the data back now!
