If I unmount a drive in Ubuntu how could I mount it again without physically reconnecting the drive?
I'm using Ubuntu 11.04

I'm pretty sure that Egil answered your question. So now that you know the behavior of clicking the "eject" button on the Desktop, lets try some command line alternatives.
One way it is possible to unmount the device without closing the USB connection is to:
This will display a list of devices that are currently mounted on your local system, as well as show their assigned mount points. (I've spaced the output below to make it easy to read)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) /dev/sdb1 on /media/1BD8-1707 type vfat (rw,nodev,nosuid,uuid=1000,gid=1000)
Your USB device will most likely be at the bottom of the list, in our case it's /dev/sdb1 and mounted to /media/1BD8-1707.
Usually all USB devices are mounted to /media/XXXX
To unmount the USB device simply type
This will unmount the disk then you can simply mount it back up by either
A: Clicking the USB icon in your Unity Taskbar or B: You can remount it wherever you please, in a different directory. See below
Thats it, you should now be able to access your usb device by navigating to /usbdrive
Try going: Places Menu -> Computer
Then you should see the disk. Double-clicking on it should mount it for you.
