# Formatting a USB Drive to FAT32 MBR on a Mac

<p>Sometimes, USB memory sticks that have been used for creating OS installation media may have a corrupted partition table, making it impossible to format them using the "Disk Utility" app.</p>
<p>You can easily format it using a command:</p>
<pre>sudo diskutil eraseDisk FAT32 USBMEMORY MBRFormat /dev/disk2</pre>
<p></p>
<p>Additionally, it's a good practice to compare the output of <code>diskutil list</code> before and after connecting the USB memory stick to determine which path it is mounted on.</p>
