Erase, Change Format Of USB / External Hard Drive In Mac OS X
1. First of all, you need to launch the 'Disk Utility' app on your Mac. In order to do this, simply bring up Spotlight search using the Command + Spacebar key combination and type in 'Disk Utility.'
2. With your USB or hard drive connected to your Mac, you'll see your disk on the left hand side of Disk Utility.
3. Click on the disk you wish to erase / format, and then click on the 'Erase' tab on the top right hand side.
4. Click on the 'Format' drop-down menu and select the format you wish to go for. If you're planning to use the drive with your Mac only, then choose 'Mac OS Extended (Journaled).' If you plan to use your drive with both Windows and a Mac as well, then opt for 'MS DOS (FAT).'
5. Set the 'Name' of the device, if you so wish.
6. Now click on the 'Erase' button on the bottom right. Confirm your action by clicking on the 'Erase' button once again, as shown in the screenshot below.

And that's it, you're done. After a few seconds, or minutes, depending on the size of your disk or the level of security you've selected, your drive will be wiped clean and ready to be used again in a brand new fashion.
If you just switched to a Mac from any other operating system, then knowing how to erase / format your device should be at your fingertips. And if you were able to follow the above steps in one go, then you've already become a Disk Utility master!
