iPartition partitions your disk quickly, easily and without losing data or reformatting. Resizes HFS+ (Mac OS Extended) partitions, keeping data intact. Intelligent partitioning means no need to manually reorganise your disk to make space to enlarge a partition… iPartition will do it for you.

Works with all types of hard disk, even removables like Zip disks and external FireWire or USB disks.

• Repartition without reformatting:
Want to change the size of a partition that’s currently full of data? iPartition supports non-destructive resize of HFS+ (including case-sensitive and journaled), FAT and NTFS partitions.

• Works with Boot Camp: *
You can use iPartition on drives that contain Boot Camp volumes; in fact, you can even resize your Windows partitions, and let iPartition take care of reconfiguring the Windows boot process for you.

• Support for case-sensitive HFS+:
Using case-sensitive HFS+ for compatibility with legacy UNIX software? No problem. iPartition can even convert case-sensitive HFS+ to normal HFS+ and vice-versa, a real boon if you’ve made the wrong choice in the past.

• Supports PC disks too:
iPartition has always had support for Apple Partition Maps, and when the Intel Macs were released we added support for the new GUID Partition Tables too. With iPartition 3, we’ve added support for PC partition tables, so you can use iPartition for your PC disks also.

• Convert disks from Mac to PC (or vice-versa): **
Even better, if you have a disk you partitioned for use with a Mac, and want to access it from a PC—or maybe you bought an external drive pre-formatted for use with a PC and now want to boot your Mac from it—iPartition can convert the partition tables for you, keeping all your data intact.

• Built-in intelligence makes partitioning easier:
Unlike other partitioning utilities, iPartition is smart. Its built-in intelligence automatically minimises the number of operations it must perform and the amount of data it must move, streamlining the partitioning process and saving you precious time.

• Power cut during partitioning? No problem:
While we don’t recommend that you rely on it, iPartition can normally recover your disk even if you pull the plug during repartitioning.

* supported guest operating systems: Windows XP 32-bit, Windows Vista (32 and 64-bit), Windows 7 (32 and 64-bit)
** iPartition only converts partition maps, not filesystems.

Limitations: Demo version will not write changes to disk.

WARNING: At present, iPartition is not compatible with Drobo. Attempting to repartition a Drobo unit may result in data loss.
