Your disk may be on the way out.Important: before you attempt anything: make sure you have a backup!!!!And, here is something I found googling:http://hintsforums.macworld.com/showthread.php?t=134145 Helpful (1) Reply options Link to this post by RoadRunn3r,★Helpful RoadRunn3r Feb 12, 2012 10:01 AM in response to babowa Level 1 (0 points) Feb 12, 2012 10:01 AM in response to babowa Now I should hit Command+R on bootup or after?

Im posting here out of desperation for some kind of help with my http://www.mac-forums.com/showthread.php?t=20062 Powerbook. It is a problem that has only started to occur in the last few days. The hard disk will begin to seek more aggressively causing itunes to skip and applications to halt. The colour wheel appears whilst the disk continues to seek and then all of a sudden it will go back to working correctly. The more applications running the more frequent the slow downs. I have been watching activity monitor whilst it occurs and none of the programs are using large amounts of processor time, infact the activity monitor itself is always on top with about 10%. Activity monitor does report large amounts of disk activity. I checked console and the system logs are reporting the following: Jun 11 20:23:13 isunk kernel[0]: disk0s9: I/O error. Jun 11 20:45:57 isunk kernel[0]: disk0s9: I/O error. Jun 11 20:46:38 isunk kernel[0]: disk0s9: I/O error. Jun 11 20:48:00 isunk kernel[0]: disk0s9: I/O error.

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 this is because I was checking where it fell in terms of warranty, but http://balloflightning.com/2010/12/io-error-os-x-hard-drive-failing/ AppleCare is only one year, not two from purchase date so this was pretty irrelevant anyways) http://superuser.com/questions/777497/unable-to-create-disk-image-using-disk-utility-input-output-error 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 I initially thought this was the work of an outdated program failing to play nice with the newest version of Snow Leopard (10.6.5) which I had installed days before.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 o error 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 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 disk utility i 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 above. Keep repeating the above process until ***** FILE SYSTEM WAS MODIFIED ***** does not appear. Even after this message disappears, repeat one more time. If this message doesn't disappear, and you continue to get disk0s3: I/O Error or similar errors, it might be time to think about punting the hard drive (or visiting a data recovery specialist if you don't have a backup). Type reboot at the prompt. You should be able to boot (hopefully). If you can, find an empty exter

The Disk Utility progress windows displays the message Creating Image Macintosh HD.dmg Reading whole disk (Apple_HFS : 0)… with progress bar that moves up to about 50% before the following error message is displayed: Unable to create Macintosh HD.dmg. (Input/output error). Using Disk Utility, First Aid, Verify Disk, the volume "Macintosh HD" appears to be OK. Is there a way to view any more detail than the console will provide? So that I can learn more about the error. It could be due to low power on the source drive - I am using a 2.5" HDD External enclosure (Mini G2 from Silicon P/L) requires 5VDC/0.5A usb to USB and power (host usb 1 - enclosure usb and enclosure round power split end cable) lead and I am using my MacBook Pro Retina, 13-inch, Late 2012 as the host USB port. The HD inside the enclosure is from an early model G4 Powerbook that was running Tiger OS X. Other answers to input/output error suggest using DiskWarrior so I tried that, DiskWarrior fixed a bunch of flags and repaired permissions but when I ran disk utility again after that to create a new image it failed again for the same reason: input/output error. Using the terminal command (from http://hints.macworld.com/article.php?story=20050302225659382) dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync does produce an image but after completion it could not be opened (or mounted) due to a "no mountable file system." mac external-hard-drive disk-utility share|improve this question edited Jul 6 '14 at 8:29 Jens Erat 8,800112744 asked Jul 6 '14 at 7:52 Jacob 103113 Sounds like you have an irreparable error on the disk.
