I need to reformat a USB-stick in FAT32 MBR.
Is it possible to do that on a Mac ?
Yes, you can.
To (re)format a drive, like a USB-stick, external HardDisk or external SSD in FAT32 MBR (MBR = Master Boot Record) do this :
- plug the drive (USB-stick) into you Mac
- make sure that there are no files or documents you need to keep left on the drive (USB-stick)
- copy all files and documents you are not willing to lose to your internal disk space, or to another external drive
- goto Applications –> Utilities –> Disk Utility
- double-click on the application’s icon to startup Disk Utility
- in the window that opens, click on the View-button (top-left) and select “Show Alle Devices”
- then, select the drive (USB-stick) from the list of drives on the left
- it should be listed in the “External” chapter
- make sure you select the drive itself, not the formatted partition that is on it
- drives are listed entirely on the left (and have a small triangle in front if they are formatted)
- partitions are listed shifted slightly to the right of the devices list
- then, click on the Erase-button (top-center, just below the Disk Utility name)
- in the pulldown window that opens, select these settings :
- Name : Untitled [ …or any name you prefer, the choice is up to you ]
- Format : MS-DOS (FAT)
- Scheme : Master Boot Record
- then click on the Erase-button
- now, wait for the process to complete
- then, click on the Eject-icon (underlined triangle) next to the name of the drive (USB-stick) in the list on the left
- when de drive (USB-stick) disappears from the list, you can unplug the USB-stick (or external HD or SSD)
- close the Disk Utility app
That’s it !
