sudo mount -t hfs /dev/disk3s2 /mnt (create /mnt folder before: sudo mkdir /mnt).Here are different methods of mounting of the volume: If won't help, to repair a volume that won't mount, follow this guide. You should boot into single-user mode (hit CMD- S at startup) and try to run repair manually: fsck -y I'll want to know if there is anyway to rescue the system without reinstalling Mac OSX or at least a way to recover some files from the drive before reinstalling Mac OSX. Tried fsck_hfs from Recovery Mode terminal then got Macintosh HD cannot be repaired. I booted in recovery mode then tried verify and repair disk with disk utilities put is seems to be OK. Hfs_mount: journal_open = NULL couldn't be opened on Macintosh HDįIP USER Space POST: Integrity test failed!īootCacheControl: could not unlink bootcache playlist /var/db/aylist: 30 Read-only file systemĪfter that it just gets stuck and never gets past that. Jnl: disk0s2: journal_open: Error replaying the journal!

Jnl: unknown-dev: update_fs_block: failed to update block 2 (ret 5) When booting in verbose I noticed the following. At restart computer doesn't boot anymore.Shutdown computer by pressing power button for 10 seconds.Trackpad and keyboard responsive once again, but after trying to close some programs computer freezes.Closed the lid, removed the USB mouse then opened the lid again.Mouse nor trackpad nor keyboard responded.Lifted the lid then connected USB mouse.I can only boot from Recovery Mode or DVD. (Neither Normal, Safe mode nor Single User). It's also worth noting that a combo updater accomplishes almost exactly the same thing as a permissions repair, and can actually take less time to run.My main HDD is failing to boot. I may have had success with those two techniques on a total of two or three occasions each, in all my days. Lots of code to look through and I was short on time, ctrl-w was insufficient.Īs for caches and permissions, it's been my experience that those are helpful only on extremely rare occasions. Yes I do seem to have missed the launchctl load commands, I was looking for a kext load. Perhaps you'd care to author the Lion version of AppleJack though. There is an optional RAM test module (installed separately).īut those functions are a fairly basic set which users who aren't Unix gurus can use to do stuff by simply selecting a number. would require more than fsck and plutil (including knowledge of where all caches are located).Īnd we are currently discussing the complexities involved with doing. (is there a way to load diskarbitration framework by hand?) But at least I could "du -sh" to see how much data I was dealing with. Unfortunately diskutil is not available in single user mode so I wasn't able to look at disk info on the bad drive. mounted the internal drive read/write, used mount to manually attach the external drive, and was able to ditto the /Users folder to the other drive.Īn interesting twist, this one wouldn't let me make a folder in /Volumes, or anywhere else for that matter, as a mount point for the second drive, but /home was there and available (and empty) so I used that as the mount point. attached another hard drive and booted into single user. OK, that's about it for options.īut I thought, hey, it boots a little, what can I do in single user mode? enough, it appears. Run diskwarrior and it won't even scan due to a "hardware malfunction". (this one was shutting down due to fsck fail safety) Try to boot off another hard drive and the boot volume won't mount. Boots to gear or somewhere abouts there and hangs or shuts down.
