    Can someone guide me through the steps in how to partition a 1TB hd into two partitions. One NTFS 750gb and the other HFS+ 250gb!

    You will need to do this in two steps. The first is within Mac OS X to separate the partitions the second is to use Windows to convert from NTFS to FAT32.

    In disk utility click on the partitions tab. There you can set the size for each of your partitions. Within make your Mac OS Extended (HFS+) and MSDOS (FAT32) partitions.

    Mount the hard drive on a Windows computer. Then go to Control Panel > Administrative Tools > Computer Management > Disk Management. From there you can reformat your newly formatted FAT32 partition into NTFS.

    Thanx velocityg4, looks pretty clear!
    Now... before posting this thread, this is what i had tried to do! Actually i did the opposite, i started with making the partitions in Windows, made a primary, formatted it NTFS, then made a second primary and left it unformatted. Then i connected the drive to the Mac (already had macfuse installed). The NTFS partition was recognized, but i couldn't see the unformatted one. So back to windows again, format the unformated as NTFS, then back to OSX again, i tried to erase the 2nd NTFS partition as HFS+, but hey presto... the result was that the whole drive (both 1st and 2nd partition) was HFS+ partitioned! Why the heck did that happen?

    I would reformat the whole drive and do it how velocityg4 said.

    I think you can do it easily using iPartition.

    Velocity i did exactly as you said only there was no option for Fat32 formatting, i just left it unallocated/free but when opening the Device Manager in Windows, there was a 128MB empty unallocated space, how can i get rid of that or join it to the partitions already existing?

    When partitioning with Disk Utility did under Volume Scheme did you select 2 partitions or did you simply adjust the partition sizes by entering the size or moving the sliders? I ask since you tried partitioning the first time around in Windows. When setting a partition scheme in Windows, Windows leaves a small amount of free space for the Master Boot Record. I do not think Mac OS X since it does not use the MBR.

    In case there was a miscommunication I will break down the steps
    1. Open Disk Utility.
    2. Select the Hard Drive to be formatted
    3. Click the Partition Tab
    4. Under Volume Scheme select the desired number of partitions
    5. Click on each of the partitions to choose the Size, Name, and Format
    6. Click Partition to partition the drive
    7. Mount the drive in Windows
    8. Open Control Panel > Administrative Tools > Computer Management > Disk Management
    9. Within Disk management right click the FAT32 partition and you can choose to Format as NTFS (quick format should do)

    For making FAT32 in Mac OS X
    MS-DOS File System = FAT32

    I believe this should clear up that 128MB of free space seen in Windows. I could be wrong. It has been a while since I have formatted a drive in HFS+ and NTFS. I just use multiple hard drives instead.

    Maybe they changed the name of that option or removed it in 10.5. I am still using 10.4.

    If memory serves right, you won't get the FAT32/MS-DOS format option if your partition scheme is Apple Partition Map (under OPTIONS in Disk Utility), since msWin won't see APM disks. You should use the GUID partition scheme for them to show up.

    So you are suggesting to make the HFS+ part selecting APM scheme and then change it to the GUID scheme to make the Fat32 partition? Is that what you are saying?

    Not exactly. Partition using GUID on the Mac, then format for HFS+ on the Mac, then move it to msWin and format the other partition to NTFS (msWin will most likely see the GUID disk fine). [Or do FAT32 for the second partition on the Mac and convert it to NTFS on msWin, as velocityg4 said.]

    Partition scheme is one level higher than formatting the partitions (one scheme per DISK/Volume).

    See http://www.kenstone.net/fcp_homepage/partitioning_tiger.html

    (Similar in Leopard)

    On the 4th picture, See OPTIONS at the bottom and click on it. Then see the very last picture to select GUID partition map. After you select GUID scheme and partition the disk, the very bottom of the page (on the 4th picture) would say GUID (or GPT), instead of APM as shown in that diagram. At any point after you see the OPTIONS not grayed out, you should be able to change the partition scheme. Note the DISK is selected on the left side, not the partitions. Once you make the GUID scheme, you can repartition your disk again (in case you had partitioned it differently) and it will stay GUID/GPT, so you can experiment a bit before committing to the final partition scheme and format for partitions.

    Then you can do steps 3 and over from velocityg4's message with the steps. Sorry I don't have a spare drive to experiment at the moment.

    Ok, here are the steps (copied and modified from previous post)

    1. Open Disk Utility.
    2. Select the Hard Drive to be formatted (DRIVE, not partition)
    3. Click the Partition Tab
    4. Under Volume Scheme, click and select 2 partitions
    5. Click OPTIONS at the bottom, Select GUID Partition Table, Click OK
    6. Click on a partition, adjust the size of the partitions to your liking by dragging the line between the partitions (250 GB and about 700 GB or whatever is left over)
    7. Click the 250GB partition and select on the right, Mac OS Extended (Journaled)
    8. Click the other partition and select MS-DOS (or FAT)

    In steps 7 and 8, you can rename partitions to your liking, use simple one word names (Partition1 and Partition2)

    9. Click Apply at the bottom and confirm the partitioning
    10. While still on the Partition tab, confirm GUID at the bottom of page
    11. Now click the Partition1 and at bottom left, verify it is Mac OS Extended (Journaled)
    12. Click Partition2 and verify is is MS-DOS (FAT), (probably FAT16)
    then Eject the disk from Mac OS X
    13. Mount the drive in Windows
    14. Open Control Panel > Administrative Tools > Computer Management > Disk Management and select this disk
    15. Within Disk management right click the FAT partition and you can choose to Format as NTFS

    DONE

    [Note Mac can only read NTFS (not write) partition unless you install third party software like MacFuse/NTFS 3-G)]

    Good luck.

    Thanx so mutch for the steps... so the whole thing was selecting GUID and not APM? What is the difference between GUID and APM?

    Useful thread. Thanks.

    Thanks for the helpful info everyone. I ran into the same thing yesterday on a friend's computer. I initially chose APM because it's an old iBook. I'll give it another try following your instructions when I get home.

    As I understand it, it needs to be GUID for an intel mac to use it as a boot disk, and APM for a PowerPC to use it as a boot disk.

    My question: will Time Machine work if I use GUID on this iBook? If no one has the answer, I'll just try it out and post my results.

    Interesting question, but i have a feeling that TMachine in order to work is only looking for HFS partitions... i think. Well if you dont get an answer then the trial and error and report:D "drill" is appropriate!
    Good luck, im with you on this bro! ;)
