Not that I am aware of. Here is the mount output:

root@finn:/etc# mount
/dev/sda1 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
/dev/sdb1 on /usr type ext3 (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
nfsd on /proc/fs/nfsd type nfsd (rw)
usbfs on /proc/bus/usb type usbfs (rw)

lsof | grep hdf does not return any results.

is there some other way to find out?
