Is there a tool that can be used to partition a disk (SD card in particular) from the command line? The purpose of this is for batch processing and customized GUI.

I doubt it will work on an SD card, but here is the command: diskpart

KCotreau is right. You can use DiskPart, which is more powerful as a graphical disk management tool.

But there is a problem for some USB sticks and SD cards: They usually don't have a Master Boot Record (MBR).

In such case you have to delete the existing partition and create a MBR. After this, you can create more than one partitions. But sometimes you have to assign drive letter manually, because Windows recognizes just the first partition.

BTW: A advantage of an existing MBR is, that you can boot from such a media.

You can create more than one volume on the disc, but Microsoft's tools themselves won't enable you do so and Microsoft's operating systems won't like you for doing it. – JdeBP Jun 21 '11 at 12:44

Perhaps an unusual solution, but you could just boot Linux (even off an SD card!) and use the excellent cfdisk. Or fdisk.
