yesterday noticed some slow-downs in my mac and decided just to reboot it. ordinary mac boot - grey screen, sound, apple logo and wheel... supposed to go away after a while. but 40 minutes was not enough for loading. googling awhile and trying suggested approaches, even magic dances, all resulted in zero.
loaded in single user mode (pressing command+s on boot, before apple logo appears) and checked disk with fsck showed that it cannot be repaired: "Invalid catalog records type (4,32450). Fsck failed. The volume could not be verified completely". so i've found this awesome app - DiskWarrior, followed the instruction for making bootable pendrive (in my case i had only one mac, so i've loaded in recovery mode for OSX Lion, chose Disk Utility and did all the stuff for making bootable pendrive from the .dmg of DiskWarrior which was on removable hdd connected to mac).
then, i've loaded mac from this pendrive, chose my MacintoshHD for rebuilding (visualizing graph failed for some reason for me) and crossed my fingers. after 20 minutes, warrior reported about successful creation of new directory structure which is going to replace the damaged one. app notified that "There is not enough free space fot fail-safe replacement..." and interruption for few seconds could cause big headaches in the future, but i risked and proceeded with that. about 10 minutes of magic and MacintoshHD was recovered. i've closed DiskWarrior, restarted and ejected pendrive from mac...
grey screen loading took few minutes and i was about to become frustrated, but finally, it showed me login screen which threw me into euphoria and sigh of relief...
i definitely recommend using DiskWarrior for "grey screen of death" issues. application is apple-simple and intuitive, being powerful recoverer at the same time. awesome!
