resize the mac partition?

[SLy CaT]

apparently ipartition and volumeworks do not work.

 

is there any other way to resize the mac partition? i want to make the partition smaller so that i can create a fat32 partition on the hd i have os x on.

 

this sounds kind of promising... but is there a way to resize without downloading ubuntu?

Yep you can.

 

Here's the method that I used.

 

In Mac OS X pull up a terminal and type:

 

cd /volumes/

 

then type

 

ls

 

It should list your available volumes. After that while still in the terminal type,

 

sudo diskutil enableJournal 'volume name'(no quotes btw)

 

This makes sure it is actually on.

 

Then we'll make sure to turn it off. Just as a note journaling NEEDS to be disabled before you can resize your partition.

 

 

sudo diskutil disableJournal 'volume name'

 

Then reboot OS X.

 

I used a gparted LIVECD which you can find right here gparted, instead of the ubuntu disk. It's ONLY 30 megs btw!!

 

Boot the LIVECD, BUT don't use the GUI version just yet.

 

Minimize gparted, right click the empty blue background and click on 'aterm', and it should bring up a terminal.

 

From there type:

 

parted

 

Parted should run and it should default to a hard drive. But make sure you select the hard drive you want to work with though .

 

If parted chose the wrong drive simply type:

select /dev/hdb or /dev/hdc or /dev/sda

Or whatever your hard drive is.

 

Now that we selected your hard drive, we have to make sure we want to resize the correct partition number.

Type out

print

to print out your partition table for that drive.

 

Now make a note of your partition number.

 

Now, we are ready to resize.

 

resize 1 32kB 20GB

 

1 is the partition number you noted, 32kB is the start of the partition, and 20GB is the end of the partition. Of course, this might be different for you.

 

ONE NOTE about PARTED THOUGH, and this is really IMPORTANT.

 

After the resize, parted seems to have changed my filesystem from a type AF drive to a type 83 which is a linux filesystem. I dont know if it'll happen to you but it happened to me, probably because i had an existing linux filesystem on it from beforehand but you never know. But don't worry this is easy to fix.

 

If parted does change your file system, use a partition table editor like this one, and change the partition type from 83 back to AF. Also make sure your boottype for your Mac OS X partition is 80. Which means bootable.

 

Let us know if there are any problems.

=D resizing worked. i was a lil scared for a second when it said invalid hfs partition, but i changed the partition type to AF and its working =D thanks /es

 

now i gotta figure out how i can format the free space into fat32 =\ i could just go into any old disk utility thingy and make it into a fat32 partition right? and it'l be accessible in osx?

 

edit: yup, it is

 

thanks a bunch for your help /es

So I tried resizing my hfs partition and it didn't work. gparted said that it was unable to satisfy constraints on volume (the GUI ver wouldn't let me increase the size either, only move the partition around the free space on my drive).

 

what gives?

 

I check the gparted manual and it says that it doesn't have resize support for hfs?????

 

any suggestions?

 

- mnx

I tried it, but now whenever i try to boot, i get "b0 error".

 

EDIT: made the part bootable and this was fixed

So everything's ok? I'm glad. Please don't revive super-old threads like this one...

 

Rather reply in the one you just created..
