Unmount of all volumes on disk2 was successful. make sure you've selected the right volume name, then start to unmount it by typing the command: It might be different on your Mac.ģ: Apple_Boot Recovery HD 650.1 MB disk0s3Ġ: Apple_HFS Macintosh HD *249.8 GB disk1 Launch the Terminal and type the following command to list volumes. Note, you can select MS-DOS (FAT) for the Format. Connect your USB to mac computer, then perform Format or Erase for your USB drive by using Disk Utility (under Application/Utilities). Back up your USB drive first as your USB drive will be erased completely before you start. The first way I recommend is by using dd commend-line under Utilities, which is able to make a byte-for-byte copy of ISO image and partition table, you should know dd is a command line-only interface, which is somewhat advanced and might not suitable for the low skilled mac users. Burn ISO File to USB on Mac in Virtualbox Burn Windows ISO to USB on Mac with Terminal The current version of ImageUSB is v (2449 KB). In this scenario, users will need to reformat the UFD in order to access the rest of the storage space. For example, if a 2GB image is copied to an 8GB USB Flash Drive, the drive will only be able to use two out of the eight gigabytes of storage space. Warning: Due to the forensic nature of image duplication by ImageUSB, please ensure that you select UFDs with a storage size similar to the image you wish to duplicate. As of V1.5, imageUSB now supports extraction of ISO contents onto USB Drive. A reformat can recover the drive however. So the direct imaging of ISO9660, Joliet or UDF file system, from a CD, to a USB drive, might not allow the USB drive to function in all operating systems.

Unlike other USB duplication tools, ImageUSB can preserve all unused and slack space during the cloning process, including the Master Boot Record (MBR). ImageUSB can also be used to install OSFClone to a USB Drive for use with PassMark OSForensics™. ImageUSB also supports writing of an ISO file byte by byte directly to an USB drive (*). Capable of creating exact bit-level copies of USB Flash Drive (UFDs), ImageUSB is an extremely effective tool for the mass duplication of UFDs. ImageUSB is a free utility which lets you write an image concurrently to multiple USB Flash Drives.
