It's also in ports: sysutils/testdisk.

>From my "famous list of data recovery programs", something else
comes to mind which probably won't restore the previous state,
but could be used to obtain the data:

	fetch -rR <device>

Also recoverdisk could be useful.

The ports collection contains further programs that might be
worth investigating; just in case they haven't been mentioned
yet:

	ddrescue
	dd_rescue
	magicrescue
	testdisk
	recoverjpeg
	foremost
	photorec
	fatback

Note that those also emphasize data recovery in the first place,
and some of them even work "without file system".

Then also

	ffs2recov
	scan_ffs

should be mentioned. And finally, the "cure to everything" is
found in The Sleuth Kit:

	fls
	dls
	ils
	autopsy

In worst case. Just in worst case.
