Use disk utility. Select the erase option then select your disk to erase, then click on security options, then choose zero out data which is less secure and takes less time than a 7 pass erase which writes data over the entire disk 7 times. This option is less secure than a 35 pass erase which probably, depending on the size of your disk, will take 12-24 hours.
It all depends on how much you care about the info. I have used the zero out data and the 7 pass erase, but have never tried the 35 pass erase. best of luck If you are reusing the disk, I suspect zero out is the way you want to go.
