Let’s assume the external hard disk is Disk 3 (check with Computer -> Manage -> Storage -> Disk Management) and the drive letter is G:Ģ) In Windows 7, Choose Start -> All Programs -> Accessories -> Command Prompt -> Right-click & choose “Run as administrator” You should probably quit the Disk Utility application before entering this command. This command will erase the contents partition 4. Mac OS X’s Disk Utility is easy, but what to do if you have to quickly reformat an GPT/EFI disk (from Mac or Win 7) to MBR partition layaout and exFAT file system in Windows 7 or XP ? sudo diskutil eraseVolume jhfs+ MyVolume disk0s4 should make the partition visible in the Disk Utility application. If this method didn’t allow you to circumvent the MediaKit reports not enough space on device for requested operation by using the Terminal to partition the disk, move down to the next method below. However, note that there have been reliability problems with exFAT in hard use. diskutil partitionDisk disk0 GPT JHFS+ 'Partition Name' 0g Note: Replace partition name with the name you want to give to your new partition. If you need to use big, over 2 GB files both in Windows and Mac OS X’s, MBR partition format and exFAT file system could be the most practical option for your mobile HDD. diskutil partitionDisk /dev/disk4 1 GPT 'HFS+' 'MemTest86' 100 output: This gives me what I would expect, the first partition is an EFI partition of size 209.7MB and the remaining 3.6GB, on a 4GB drive, being allocated to the second partition, /dev/disk3s2, MemTest86.
