    I know that when I delete a file the data is still recoverable from the hard drive until it is replaced by other data.

    So I'm looking for a program that wipes any data (preferably with the Gutmann Wipe method) off of the rewritable parts of the hard drive. Is there such a program for the Mac?

    You can use Disk Utility to do a 35-pass erase on a drive.

    Also, for short-term security and peace of mind, you can always do a 'secure empty' of the trash which not only deletes the pointers to the file (essentially what deleting a file on any computer does), but overwrites the file with zeros.

    But if you really wanted to wipe the whole drive...a reformat and re-writing the drive with a 7 or 35 pass of zeroing out data will do. This doesn't work on individual files tho, Secure Empty will.
