How to shred disk free space

Use this procedure to clean the disk free space on a hard drive. Disk free space is the area on your hard drive containing de-allocated memory. This is where all the data you have previously deleted is stored, until it is overwritten by something else. To shred the data you have previously deleted, you need to shred disk free space. If you have a lot of disk free space or a slow hard drive, shredding free space can take a while.

If you shred the free space on a disk by mistake, don’t panic. Using this procedure will only shred your free space, not your data. We’ve made it easy to shred the free space of a disk and more difficult to shred the contents of a disk. This is intentional, so that you don’t accidentally shred the contents of a disk (i.e. your data).

  1. To erase the free space on a disk using ShredIt for Mac OS 8 | 9, drag the hard drive icon onto the ShredIt Icon and drop it.

How to erase a Hard Drive

Before disposing of a computer or a hard drive, we recommend that you erase all the files you don’t want the next user to be able to recover.

Read all of these instructions before continuing. Using the Hard Drive Cleaner function of ShredIt will erase your data, (i.e. your files), making the hard drive clean by destroying your data so it can’t be recovered. Before you erase the hard drive, make a backup copy of any data or applications you want to use on another computer before you shred the contents of a disk, since the files cannot be recovered from the disk after it has been shredded.
