This is useful for creating space for new operating systems, reorganising disk usage, copying data between hard disks, and "disk imaging" - replicating installations over many computers.
Parted has support for these operations:
Filesystem detect create resize copy check ext2 * * *1 *2 *3 fat * * *4 *4 * linux-swap * * * * *
(1) The start of the partition must stay fixed for ext2.
(2) The partition you copy to must be bigger (or exactly the same size) as the partition you copy from.
(3) Limited checking is done when the filesystem is opened. This is the only checking at the moment. All commands (including resize) will gracefully fail, leaving the filesystem in tact, if there are any errors in the file system (and the vast majority of errors in general).
(4) The size of the new partition, after resizing or copying, is restricted by the cluster size for fat (mainly affects FAT16). This is worse than you think, because you don't get to choose your cluster size (it's a bug in Windows, but you want compatibility, right?).
So, in practise, you can always shrink your partition (because Parted can shrink the cluster size), but you may not be able to grow the partition to the size you want. If you don't have any problems with using FAT32, you will always be able to grow the partition to the size you want.
Summary: you can always shrink your partition. If you can't use FAT32 for some reason, you may not be able to grow your partition.
Repairing corrupted partition table
Because I use only Intel x86 machines, any contributions (or non-x86 machine donation ;-) ) are very welcome. If you can provide any useful information, don't hesitate to mail me.
UnixWare VTOC (Volume Table Of Contents) divides disk partition to 16 logical partitions. Linux kernel supports UnixWare VTOC, you must check "UnixWare slices support (EXPERIMENTAL)" and recompile your kernel. Another way of reading UnixWare disklabel is using GPL port of prtvtoc(1) command, which is in vxtools package.

Logical Volume Manager is available in OS/2 WarpServer 5. It allows you to create linear volumes on several disks/partitions. Some people say that it's compatible with IBM AIX Logical Volume Manager.
StackVM is CrosStor's volume manager. Using StackVM the administrator can combine multiple physical disk slices into a single logical device know as a vdisk. Vdisk is short for virtual disk. The physical disks can be combined to form a concatenation, RAID 0 (stripe), RAID 1 (mirror), RAID 4 or RAID 5. In addition a single disk partition can be subdivided into multiple simple vdisks. For more information see CrosStor homepage at http://www.crosstor.com/.
NetWare volumes are used for NWFS-386 filesystem.
