Database removable

Hello,is possible attach and use the mdf exists in a pen drive or an usb
hard disk ?
What commands are involved in this operation '
Thanks in advance.I have a lot of DB allocated on my USB (or Firewire) external disk; even a
pen drive is managed by the OS as an external, removable disk.
The only attention you hav to pay is to remember detach you removable
database when you suppose the next startup of your PC will be without the
external disks containing your databases.
When you need to use such databases you'll attach it again
