One way to hide your data is by using an obscure file system that uses parts
of the hard drive not normally used by the more popular file system.  An
example of this product is 2M Formatter.  It can store 1.92 or more megs on
an old 3 1/2" floppy.  The formatting of normal 3.5's is 1.44 (1457664 bytes of
data, howver there are sectors or tracks that can be boosted to greatly improve
the capacity of the floppy disks.  Even if someone formatted the disk, if the
data is held in the unused sections they would have a very good disguise. 
Another idea is to encrypt a single file on to the disk, delete the file,
making it look empty, then do a file recovery and make that encrypted file
reappear.  With the old 3.5's you could also delete the serial numbers
encoded on to the disk simply by wiping a neodymium magnet around the outside
of the disk and reformatting it.  The reformat will show a serial number of
all zeros.
