Replace the drive or do the following... Back up everything of value via Target Disk Mode (if possible) then boot your MacBook from a USB or DVD installer. Run Disk Utility, selecting the secure erase/zero fill option and wipe your drive. This will issue an ATA secure erase command that will fill every allocation block with a zero, automatically mapping out any bad blocks/sectors that will be causing your I/O problem. This is the modern equivalent of the old low-level format, and while there is some debate on the subject I use this method regularly and it w

I/O error, stuck on grey screen Mid 2009 Macbook i/o error Pro, Mavericks I've got a serious booting issue going on. The first symptom was my computer not being able to boot past the grey apple logo screen with the spinning gear. The fsck command in single user mode apparently came up okay, but verbose mode revealed "disk0s2 I/O error" I was finally able to get it to boot to the recovery partition but multiple things go wrong here. First of all, Disk Utility cannot repair Macintosh HD, and trying to make a back up to disk0s2 i/o error an external results in something like "cannot copy, I/O error." Furthermore, I cannot use the reinstall OS X application, because it says I am not connected to the internet, even though the network utility says I am, and I can actually use Safari successfully in the "Get help online" option. Lately, my computer boots to the recovery partition by default, even though disk utility shows that Macintosh HD is mounted. When I go to "copy image" I can even see all of my files (what a tease!) I also recently noticed something in single user mode; when I ran fsck before, it checked "OS X Base Volume." When I get it to check Macintosh HD using fsck_hbn -fy /dev/disk0s2 it comes back with the same "disk0s2 I/O error." Any ideas about what the hell is going on here? It sounds like my hard drive has failed, but if that were the case, why would it say it is mounted in Disk Utility, and how am I able to look at all of my files? And if my HD did indeed fail (or the SATA cable or logic board for that matter,) how am I able to access the recovery partition? One final clue: the night before this happened, my computer, which was plugged up to a charger, suddenly turned off and my charger hasn't worked since. I got a new one and it works fine. When this happened, there was fan plugged into the same outlet that continued to function prop
