Colin My Macbook (late 2008 Unibody) turned two years old a few days before Christmas. The day after it's birthday (the only reason I know fsck disk full error this is because I was checking where it fell in terms of warranty, disk0s2 i/o error invalid node structure but AppleCare is only one year, not two from purchase date so this was pretty irrelevant anyways) I started to

suffer from a myriad of issues during use. Beachballing. Bouncing programs in the dock. Random freezes in Firefox when browsing. Connection dropouts. The works. I initially thought this was the work of https://discussions.apple.com/thread/4700518?tstart=0 an outdated program failing to play nice with the newest version of Snow Leopard (10.6.5) which I had installed days before. I began turning off plugins in Firefox and ditching programs from the startup menu to attempt to cure whatever sickness had taken over my laptop. Every reboot cycle gave me the same problem- the computer would run for about 30 seconds, but then http://balloflightning.com/2010/12/io-error-os-x-hard-drive-failing/ any use and it started beachballing. Finally, it just didn't reboot. The computer hung at the grey screen with the Apple logo and the spinning ball. No peripherals (external hard drive, USB mouse, etc.) were attached so that was immediately ruled out. To attempt to diagnose the problem, I attempted to boot into safe mode. Not happening. Tried resetting the PRAM and NVRAM. Nada. Finally, the next series of steps allowed me to salvage my hard drive and let my Macbook live to see another day (minus a $700 data recovery charge). Boot into single-user mode (sometimes called verbose mode) (hold down Control-V as soon as the Mac chime sounds after pressing the power button). You should now be in an environment that looks like this: At the command line type: /sbin/fsck -fy and press Return. You will receive messages about the disks use and fragmentation as fsck will now go through five phases of disk utility. If you get: disk0s3: I/O Error then you have a problem with bad sectors on the hard drive. Eventually, fsck will probably tell you: ***** FILE SYSTEM WAS MODIFIED ***** Repeat the fsck process abov

His Macbook model is: MacBook (13-inch, Early 2008). His Macbook cannot boot. When the power button was pressed, the grey apple logo and the spinning thing appears. In addition, there is a progress bar underneath. I waited till the progress bar disappears, but it automatically shuts down after that
2009 Basics, Featured, File system, Performance, Tips 1 Comment fsck is a Unix utility for checking and repairing file system inconsistencies . File system can become inconsistent due to several reasons and the most common is abnormal shutdown due to hardware failure , power failure or switching off the system without proper shutdown. Due to these reasons the superblock in a file system is not updated and has mismatched information relating to system data blocks, free blocks and inodes . fsck - Modes of operation : fsck operates in two modes interactive and non interactive : Interactive - fsck examines the file system and stops at each error it finds in the file system and gives the problem description and ask for user response whether to correct the problem or continue without making any change to the file system. Non interactive :fsck tries to repair all the problems it finds in a file system without stopping for user response useful in case of a large number of inconsistencies in a file system but has the disadvantage of removing some useful files which are detected to be corrupt . If file system is found to have problem at the booting time non interactive fsck is run and all errors which are considered safe to correct are corrected. But if still file system has problems the system boots in single user mode asking for user to manually run the fsck to correct the problems in file system Running fsck : fsck should always be run in a single user mode which ensures proper repair of file system . If it is run in a busy system where the file system is changing constantly fsck may see the changes as inconsistencies and may corrupt the file system . If the system can not be brought in a single user mode fsck should be run on the partitions ,other than root & usr , after unmounting them . Root & usr partitions can not be unmounted . If the system fails to come up due to root/usr files system corruption the system can be booted with CD and root/usr partitions can be repaired using fsck. command syntax fsck [ -F fstype] [-V] [-yY] [-o options] special -F fstype type of file system to be repaired ( ufs , vxfs etc) -V verify the command line syntax but do not run the command -y or -Y Run the comman
