I'm at 34 GB now and need more room. Can I go larger? I'm running XP on my windows side.

    You can shrink your primary (OSX) partition to make more room for BootCamp.  You would need to backup data from the XP side, delete that partition, shrink your OSX partition.  Then you can have a larger BootCamp partition after you reinstall XP.

     

    But once a partition is created, you cannot change the *beginning* location on the disk.

     

    But if your OSX partition was minimized to make room for XP, your priorities are not quite correct.

     

    It is a Mac system first.  Your OSX partition needs 10%-15% free space at all times, and if reinstalling/expanding XP partition drops that "free space" too low, it is time for a new disk.

     

    Please do not take offense to anythng I wrote ... I did not intend to insult at any point.

    I set the size of the partition based on the limit that windows could see or use with the XP software. I remember reading somewhere in the setup for boot camp that 32GB was the most that windows could address or something like that, I profess my lack of knowledge of all things PC. The Mac side is not a problem, I'm working with a 500GB drive. So what you are saying is that I can make the partition 64GB if I want? Will I have create multiple volumes on it for the software to be able to see that much space?

    I do not run XP anymore, not for years.

     

    XP is long in the tooth, and a new install will likey have 3 days of patches.

     

    Windows 7 can be had for $200 (Home Premium), and is more stable and actually acknowledged by MS as a system.  Far fewer patches after initial install, as well.

     

    As to partitions: BootCamp needs a 1 partition disk to even start running, and only two partitions can exist under BootCamp (OSX and Windows).  Both on the internal disk.

     

    I guess you can make your BootCamp partition as big as you need or want or feel the version of Windows will support.

     

    I was just stating rules about having to "undo BootCamp" to purge that partition and rebuild it to have it any larger.

    You misread the documentation, you could have made a 500G partition if you wanted to, anyhow: Delete the BootCamp partition (using Bootcamp, not disk utility) and start again.

    Windows XP has a practical limit for partitions at 2TB due to the used MBR (Master Boot Record) not being able to address larger harddisks.

     

    32GB is the limitation Microsoft has set for using FAT32 as file system.

    Partitions over 32GB have to use the NTFS file system.

     

    (Third-party tools can nonetheless format partitions greater than 32GB with FAT32).

     

    And you don't have and shouldn't create multiple volumes inside the BootCamp Windows partition as this renders your XP partition useless !!

    I'm sorry but that is a hoary old wives tale, it's also incorrect, the maximum size for a Fat32 partition is 8TBytes

     

    Here's some data about it.

     

     

    • Clusters cannot be 64 kilobytes (KB) or larger. If clusters are 64 KB or larger, some programs (such as Setup programs) may incorrectly calculate disk space.
    • A FAT32 volume must contain a minimum of 65,527 clusters. You cannot increase the cluster size on a volume that uses the FAT32 file system so that it contains fewer than 65,527 clusters.
    • The maximum disk size is approximately 8 terabytes when you take into account the following variables: The maximum possible number of clusters on a FAT32 volume is 268,435,445, and there is a maximum of 32 KB per cluster, along with the space required for the file allocation table (FAT).

     

    Hmmm, formatting is odd, here's a link to the original MS article

    I have 3 external drives, all Fat32, all 500g single partitions, how disappointing to find out that they are 'theoretical'

  • 9. Re: what is the largest partition for boot camp

    And 500g is so much bigger than 2TB ??

    The OP was talking about an internal 500G drive, you told him 32G was the maximum partition for Fat32, I think that 500G is the limit, and if he had a 2T drive then 2T would be the limit, but please keep spreading the information, correction is never far away.

    What I wrote was:

     

    "32GB is the limitation Microsoft has set for using FAT32 as file system.

    Partitions over 32GB have to use the NTFS file system.

     

    (Third-party tools can nonetheless format partitions greater than 32GB with FAT32)."

     

    Microsofts own Format program refuses to use FAt32 with partitions bigger than 32GB.

    Third-party tools do it nonetheless

    Paragon CampTune 9.5 $19

     

    That will hopefully walk through (burn ISO to CD, backup both for safety - always be ready as sometimes backup and restore is easiest and safest)

     

    convert to ntfs fs

     

    Apple Disk Utility is happy to creatye 500GB FAT32.

    Yes, for a bootable installation of XP 32G is it, but Fat32 is the wrong format for this use, NTFS should be used, none theless OSX can and will format a partition larger than 32G as Fat32.

  • 14. Re: what is the largest partition for boot camp

    From Microsofts and my own point of view OSX Disk Utility qualifies as a "third-party tool" which essentially leads back to my first post.

     

    (But all this is not useful for the OP, so -> full stop).
