How to erase a floppy disk
on Mac OS 7 using ShredIt
Before disposing of a floppy disk or giving it to someone else, we recommend that you erase all the files you don't want the next user to be able to recover.
- Using the Disk Cleaner function of ShredIt will erase your data, (i.e. your files), making the floppy disk safe to re-use because you will have destroyed the data on it so it can't be recovered
- If you don't need to destroy confidential files on the floppy disk, you can use the re-fromat floppy function in the operating system instead. This will delete, but not erase the data on the disk
- This procedure works with any Mac, Windows or DOS formatted floppy disk.

- For more detailed information about ShredIt for Mac OS 7, refer to the
- There's an important difference between the technical terms "delete" and "secure delete".
- The technical computer term "delete" refers to the type of computer function where the data is marked as deleted, but not really gone. Functions such as dragging a file to the trash/recycle bin and then emptying it marks the data as deleted so the space can be used again, but the data itself remains on the hard drive and recoverable until it is overwritten by something else. On a hard drive with lots of free space, this could take months or even years.
- On the other hand, the technical term "secure delete" refers to the type of computer function where the data is overwritten by other characters so the data can't be recovered. "Secure Delete" is also referred to as "clean", "wipe", "erase" and "shred". Computer software that performs this type of function is often called a "file shredder" a "data shredder" or "secure delete utility".
