How to get list of mounted drives?

[Shellback3]

I just installed Ubuntu 11.10 and Eclipse Indigo on a new computer that has a small system drive /dev/sda1 mounted on / and a bay that holds two removable solid state drives populated with one drive /dev/sdb1 mounted on /media/sdb1. I assume that a second removable drive would be mounted as /media/sdb2 or /media/sdc1.

My program needs to know what removable drives are mounted and the assigned name, that it my imaginative name for the removable drive is "data-0". My programy program will need to report an error if no drive is mounted, keep track of available space, and if we should have enough money to purchase a second drive, switch to the second drive if the first gets full.

I have tried to use FileSystemView.getFileSystemView() and File.listRoots() but neither returns any but the system drive.

Any suggestions would be greatly appreciated,
Nate

For want of any reply and no web searches with an answer I decided to parse the /proc/mounts file as it has current data. On my computer only the removable disk is in a line starting with /dev/sd

The next field is the mount point:

/dev/sdb1 /media/sdb1 <more fields separated by spaces>

This is trivial to parse and I can use the mount point to get information such as the disk size and amount of free space.
