fdisk and ntfs/hfs

Filed under: OS X Administration — admin @ 5:41 am

I wanted to change the type of partition from 0x0B (Fat32) to 0×07 (HPFS/NTFS)

You can find the answer in fdisk below

tsmith@ルースアニメ:~$ fdisk -e /dev/disk1

manual Show entire man page for fdisk
reinit Re-initialize loaded MBR (to defaults)
auto Auto-partition the disk with a partition style
