For the past two days I've spent the majority of my time (when
I'm not in class or at work) trying to get my 250 gig external hard drive set
up just the way I want it. My idea was
to partition about 7 gigs of it to install OS X Tiger on, and partition the
rest as a FAT32 cross-platform storage drive.
I now believe this to be impossible.
The problem is that Windows cannot read the Mac partition table, and the
Mac cannot boot an OS from a Windows partition table, although the Mac can
otherwise use a Windows partition table just fine. So now I have a 7 gig Mac HFS+ partition that
is useless on my drive. The part that
really sucks about the whole thing is that I spent about 8 hours working on
getting the partitions set up the way they are now, only to find out that Tiger
can't be installed on a drive using Windows partitioning. If for some reason you ever needed to have an
HFS+ and FAT32 partition on the same drive though, I know how to do that. In a Mac terminal window use the command
diskutil partitionDisk /dev/disk2 2 MBRFormat
MS-DOS fat32partitionName 225G "Journaled HFS+" macPartitionName 7G
This command will create 2 partitions, 1 HFS+ and 1 FAT32. Both partitions can be mounted in OS X and
the FAT32 partition will show up in Windows.
In the above command 225G and 7G are the size of the partitions you want
to create in gigabytes and /dev/disk2 is the name of the disk you are
partitioning and formatting. You can
find out the disk name on your machine by using the command
diskutil list
Hopefully someone will have use for this information. In the meantime I'll be formatting my drive
with a single FAT32 partition for storage use only.
