Once I try running the http://superuser.com/questions/906513/get-rid-of-resource-busy-message-on-mac-os-x 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 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.

Google Apps QI B.A.S. Information Technology Contact Me Format An Unformattable Flash Drive In OS X It's always satisfying to fix something that seems impossibly broken.  I recently fixed a broken flash drive that could not be reformatted.  I first tried to repair the disk using Disk Utility, but that option was completely greyed out (same thing in the Recovery HD).  So then I tried to erase it but was presented with the error "OS X can't repair the disk "MYDISK"." Next, I tried to partition the disk and received the error message "Disk Erase failed: Disk Erase failed with the error: Unable to write to the last block of the device." After some searching, I came across this helpful post.  Here are the steps I used to fix it: Find The Disk Device File Associated With The Drive First, you need to find the device file that corresponds with your flash drive.  Run this command: diskutil list 1 diskutil list You should see some entries like /dev/disk0 , or /dev/disk1 .  Take note of the one that is assigned to your flash drive.  It will be used in the next steps. Format The Drive Before The System Completely Grabs Onto It This is the weird part.  You will be using this command (make sure to substitute your device file if it is different) to write random data to the flash drive (which is essentially what reformatting does anyway): First, become root: sudo su 1 sudo su Repeatedly run this command (using the up arrow to access it again), while plugging in your flash drive until the command prompt disappears (meaning it is writing to your flash drive).  If you get the resource busy error.  Unplug the drive and try again.  You just have to get the command to run just as the flash drive is plugged in. cat /dev/random > /dev/disk1 1 cat /dev/random > /dev/disk1 Take a look here for the full instructions and details as they explain everything very well.

Or if you want real fast speed and don't care about forensics, /dev/zero. I personally use the following. # sudo dd if=/dev/zero of=/dev/rdisk1 bs=1m "rdisk" is faster then disk jacobsalmela I can surmis
