If so, use its reboot button. The Linux o/s in the NAS should run an fsck if the drive is not cleanly unmounted (i.e.: if the device is power-cycled) and ext2 is a very robust file-system, but that is no substitute for shutting down cleanly whenever possible. ext2 by default runs an fsck every 20 boots - if the Buffalo designers chose to make it do so more often (say, every time) it would slow boot times & surely result in lots of tech-support queries, but again there may be an option in the NAS's admin options to run a disk check. Stroller.
