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 unreadable, but also partition failed with the error couldn't open device unable to be reformatted. If this happens, the drive may show up in the partition failed with the error unable to write to the last block of the device Finder sidebar but not show data when clicked, or it may just not show up but be present in Disk Utility;

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 do not hear any tell-tale signs of could not mount disk with name (null) after erase 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.). These allow programs to interact directly with the device, so for instance you can

Once I try running the i command, I get an error message saying that the resource is busy: pdisk: can't open file '/dev/rdisk1' for writing (Resource busy) I get the same result when using /dev/disk1, /dev/rdisk2, and /dev/disk2. I also tried running sudo gpt /dev/(r)disk(1-3). Interestingly enough, the I only get a result from /dev/rdisk3: So, I try unable to write to see what is using the resource by running sudo lsof /dev/rdisk1, as well as sudo lsof /dev/disk1. Nothing shows up: I've also tried unmounting the device by running sudo umount /dev/disk1 as well as sudo umount /dev/rdisk1. I get a message saying that the device is not currently mounted: Here's a list of all of the disks connected to the computer, found by running sudo DiskUtil list: /dev/disk0 - The disk of the computer that the iMac is connected to. /dev/disk1 - The HDD of the iMac. /dev/disk2 - The SSD of the iMac. /dev/disk3 - I don't know what this is. I would assume it is the combined HDD and SSD of the iMac. /dev/disk4 - An external hard drive. /dev/disk5 - I have no clue what this is either. Maybe utilities for /dev/disk4? The iMac has a fusion drive, and /dev/disk1 is the HDD. I've tried with the SSD, /dev/disk2, but I get the same result. I have the iMac plugged into another computer via thunderbolt, and by holding t when the iMac started up, the Macintosh HD showed up as an external device on the other computer. How could I get rid of this message? I've tried restarting both the iMac and the computer that it is connected to. osx unix partition-recovery file-recovery share|improve this question edited Apr 30 '15 at 2:53 asked Apr 27 '15 at 1:51 Jojodmo 88116 discussions.apple.com/
