WipeFreeSpace
DESCRIPTION
WipeFreeSpace is a program to securely erase/wipe/overwrite the free space on file systems to prevent recovery of deleted sensitive data.
This allows protecting the user's privacy when e.g. selling the drive or the whole computer.
The following filesystems are supported:
- Ext2/3/4,
- NTFS,
- XFS,
- ReiserFSv3/4,
- FAT12/16/32,
- MinixFS1/2,
- JFS,
- HFS/HFS+,
- OCFS.
The following wiping methods are supported: Gutmann-like, random, Schneier, DoD.
Additionally, WipeFreeSpace can finalize wiping the filesystem by writing blocks of zeros, which is friendly for sparse files, virtual systems and other places where zeroed-out space is not physically allocated.
See the project homepage https://wipefreespace.sourceforge.io and the project Wiki in the menu above.
To prevent clear-text data from being left on the drive in the first place, you can take a look at LibSecRm (https://libsecrm.sourceforge.io), which wipes the data on-the-fly.
