Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on th

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 https://discussions.apple.com/thread/1662948?start=0&tstart=0 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 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, https://www.ifixit.com/Answers/View/102528/Input-output+error+after+replacing+Hard+Drive 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.

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 https://www.macissues.com/2014/04/05/how-to-fix-deep-formatting-problems-with-os-x-drives/ drive not only being 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 https://macosx.com/threads/mac-os-x-install-cd-detects-new-hdd-as-being-7-25x-actual-size.320855/ 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 disk erase or one claiming the drive cannot be unmounted, when 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 disk erase failed causes the drive to hang when accessed. This is especially true if you 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 c

However, Mac OS X install CD detects the new HDD as being 7.25x actual size, claiming it is 1.16 terrabytes in volume. This is causing a bunch of headaches, because I cant get the install software to do ANYTHING with the disk. - It will not show up as an available disk to install mac OS X on. - Trying to partition gives the error: Partition failed, Partition failed with the error: input/output error. - Trying to erase the disk gives the same error (read that worked for some people). I have tried using MacDrive9 to create a partition and then install mac OS X on the mac book. The disk utility recognizes the partition as the appropriate size; however, again, it wont touch the drive. Trying to perform operations on the drive gives the error "Disk Utility Internal Error: Disk utility has lost its connection to the disk management tool and cannot continue. Please quit and relaunch disk utility" and the only option is to shut down the disk utility. The exception to this is verifying and repairing the partition with disk utility. The disk goes through the verification and repair process normally, with no errors reported. Manipulating this drive in Windows with MacDrive9, or windows itself with the drive barren, yields no problems at all. The drive is fully functional, and recognized as the appropriate size. Any help would be great, because I cant seem to figure out, or
