Read/Write scan passed but when it came to Surface Scan, it spilt out lots and lots and lots of bad blocks.So, can I assume

This procedure will write zeros to all sectors. The drive will attempt to map out any bad sectors.

Another possible symptom is if you get this error or one https://discussions.apple.com/thread/1503696?start=0&tstart=0 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 causes the drive to https://www.macissues.com/2014/04/05/how-to-fix-deep-formatting-problems-with-os-x-drives/ 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 collection of drivers in the hidden "/dev" di

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.
