fails to automount external HDD

view story

http://crunchbang.org – On my last startup my external HDD failed to automount. Working fine previously. When I try a mount a previously connected (but not anymore) usb stick shows up ostensibly showing the files it had when it was mounted. But that was prior to reboot. Thinking back, I think I umounted it manually - would that be the issue?Using latest stable statler bpo for 64bit. (HowTos)
