I want to split a large external USB hard drive into at least 2 partitions.
I've heard that multiple partitions on a USB drive involves problems not associated with partitioning a regular IDE/SATA hard drive, especially with Windows. But I can't find specific information about it.
What are those specific problems, and how are they avoided or worked around? Do journaling file systems like ext3, ext4, xfs present special concerns for a USB drive? What are the particular problems Windows has with a partitioned USB drive that don't exist with regular internal drives?
I plan to use Linux (most likely GParted) to do the partitioning. I also plan to use Truecrypt's whole-partition encryption on the partitions, so a thief doesn't have easy access to the data.
