What's using the disk so much?

vmstat reports that quite a few processes are waiting for io (disk access)
so I ran gstat to see how much the drive is working and it says more or
less 100% constantly.
How can I determine which process (if it's mostly one single process) is
using the disk so much? top says the CPU is mostly idle.
