Disk Warrior seems to be one of the decent utilities to try when fsck won't work - but unless you have lots of specific corruption issues - the time you spend wiping and reinstalling usually doesn't outweigh the cost of that software. The second option doesn't have great promise. I've also not had much luck forcing fsck_hfs to rebuild parts when the plain /sbin/fsck -fy fails - but you could get lucky there with an unusual corruption pattern on this drive. In my expereice, if you don't have lots of IO errors ( -B option for fsck_hfs) then the erase will restore full function and you can reinstall the OS and restore from backup. seek other software options to attempt repair.back up what you can/need to and erase the volume.When you can't get a clean run of fsck (which you might need to let run for a handful of hours) - then it's time to make a decision: To repair the hard drive you generally use /sbin/fsck -fy, right? The only problem is that gives me the same as before, hanging on the catalog file.

It proceeds to hang here until I ^C out of fsck. So I try using single-user mode, because obviously I'm not getting anywhere with this boot-up loop.Įxecuting fsck_hfs (Version hfs-305.10.1). A couple minutes later the computer reboots and the process restarts.After hanging with a white screen for ~4 minutes, it switches to a blue screen with vertical red stripes.Rendered pixels are generally shifted up or down a single pixel every few inches across the screen.Screen occasionally has a black stripe with rainbow pixels dotted across the top of the screen.Initial loading screen has a green progress bar.Screen is generally slightly tinted green, with light green horizontal stripes going across the display every couple pixels.Fan activates loudly while starting up.Computer doesn't get past initial boot up loading.This morning I tried turning the computer on, and it had a few issues.
