It normally runs very well but the hard drive I installed several years ago needed replacing. All went well. Now comes time to install the software. I'm installing disk one and the message is: Disk Erase Failed Input Output Error. I have examined and followed the threads about this issue but to no avail. It seems that the old threads have this issue well pegged but my machine is not responding as it should. No injury has occurred to the machine. For several months it has been driving a 23 inch monitor and playing my tunes for me along with an occasional back up. No heavy lifting. I have used disk utility obviously and I tried to both erase and partition. I highlighted the drive that I wish to erase--it's the new one with nothing on it. Ideas?

G'day and welcome to the forums. Changing hard drives in a MacBook can be pretty hard on the cables which get brittle with heat and age. Check the cable carefully. Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

It's a MacBook Pro 13" Mid 2009. After it failed to boot up past the grey screen, I took it to the Genius bar at my local Apple store, and the guy told me the hard drive had definitely died. Thank god I'd done a Time Machine back-up recently! I did a https://www.ifixit.com/Answers/View/102528/Input-output+error+after+replacing+Hard+Drive bit of research, (I'm not very knowlagable about computers), and eventually chose a Crucial m4 SSD, 256GB, 2.5" SATA 6Gb/s to replace it with. Crucial claim this is definitely compatable. All seemed fine as I put it in, but when I came to install the OS, I got a bit stuck... There was no 'destination' to install to, so I went to Disk Utility. The new hard drive shows up, but there is no option to "Repair Disk" under First Aid (it's greyed out) and when I tried to erase and re-format the hard drive - I selected Mac OS Extended (Journaled) - it comes up with an error message: "Disk Erase failed with the error: Input/output error" I've Googled the heck out of this, and although others have been asking similar questions, I still can't make sense of it all. Am I missing something obvious? If anyone has any pointers that would be so great. Thanks in advance guys :) Answer this question I have this problem too Subscribed to new answers Is this a good question? Yes No Voted Undo Score 0 Cancel Add a comment 0/1024 Cancel Po
with OS X drives 97 Replies Even though formatting advances like Journaling in Apple's filesystem formats help prevent data corruption, problems can still happen that result in a drive not only being https://www.macissues.com/2014/04/05/how-to-fix-deep-formatting-problems-with-os-x-drives/ unreadable, but also unable to be reformatted. If this happens, the drive may show up in the Finder sidebar but not show data when clicked, or it may just not show up but be present in Disk Utility; however, if you try to mount it you get a "resource busy" error. Another possible symptom is if you get this error or one claiming the drive cannot be unmounted, when disk erase trying to format the drive or running a fix routine on it with Disk Utility. These errors and behaviors might indicate to you that your drive is malfunctioning and you need a new one; however, before you give up on a $100+ drive, ensure the problem is not simply a very low-level formatting snag that causes the drive to hang when accessed. This is especially true if you disk erase failed do not hear any tell-tale signs of physical failure, such as repeated click, tap, and whirr sounds coming from the drive at regular intervals. Assuming the drive is just experiencing major low-level corruption, the problem you face now is how to format a drive that apparently cannot be formatted on your Mac? One option is to use another operating system like Windows in Boot Camp, in a Virtual Machine, or on a dedicated PC to manage the drive and attempt to repartition it; however, this may not be feasible in some situations. Another option that should work in most cases is to use the Terminal to interact with special device files to force an overwrite of the device file representing the drive. OS X Device files The /dev folder has a number of different device files that are assigned to system components and peripherals, allowing programs to interact with them using system calls. These devices include disks, consoles, terminals, and standard input and output, among others (click for larger view). Device files in OS X are a collection of drivers in the hidden "/dev" directory that are assigned to devices, allowing them to be accessed by system calls (open, read, write, close, etc.). Th
