BTW if one does hose the filesystem on a bsd ufs2 (SUJ) disk,
may be a quicker fsck of it. (Vs the added parameter above, which seems to work on most any thumbdrive or usb/ide or sata, at least
the few I've had to run it on.)
Code:
fsck_ffs /dev/ad10p1 # not fsck_ffs -y /dev/ad10p1
# some systems may hang "using the journal == yes == -y "
# ... if they have little memory or a flakey controller, for example.the few I've had to run it on.)
