#DRIVE WIPER FREE SPACE ONLY PORTABLE#

However, if that is not a problem for you, then the program is great! It’s portable and doesn’t require any installation, so you can carry it around on a USB stick or just email it to yourself. And since it’s a Windows app, it can really only erase hard drives that are Windows formatted (NTFS, FAT32, FAT, etc). The only downside is that it is a Windows app, so you have to run it from within an already existing operating system, whereas the other two mentioned above can be booted to using a CD or floppy disk. Disk WipeĪnother good freeware app is Disk Wipe. If you need to erase a large number of disks, it might be worth the monetary investment, otherwise you’re good with the free version. You can use the program from within Windows directly, via DOS or use bootable media so you can wipe any disk whether it was running Windows, Linux, OS X, etc. If you do purchase the program, then you have a great set of 17 choices for deleting your data: Definitely DBan is better since you can use the DoD 5220.22-M protocol. The free version only has one way to delete the data on a hard drive (erasing with one-pass zeroes), but it’s still good enough for a decent hard drive wipe.

The professional version is definitely better than DBan in terms of options, but it’s not worth shelling out $40 or $50. KillDisk comes in two flavors: Free and Professional. If, for some reason, DBan does not work for you, you can try out the other programs mentioned below. I’ve used this program several times and have found that it does an excellent job erasing data on many different types of hard drives. Most files have sizes that are not 4KB increments and thus have slack space at their end.You can choose from different wipe methods including Gutmann Wipe, Department of Defense Short and Medium and others. Free space to be wiped is found in the 'tail' end of a file because disk space is usually allocated in 4 KB clusters. This relates to any regular files located on any file system. Specifics of Wiping Algorithms for Different File Systems KillDisk therefore offers extra steps to ensure secure deletion. Deleted information may be kept in additional areas of a drive. A majority of software that advertises itself as performing reliable deletions simply wipes out free clusters. Unwanted information may still be left available for recovery on the computer. The process of deleting files does not eliminate them from the hard drive. Wiping drive space can take a long time, so do this when the system is not being otherwise utilized. KillDisk wipes unused data residue from file slack space, unused sectors, and unused space in MTF records or directory records. This means that deleted Windows system records can be wiped clean. As a result, the wipe or erase process uses an operating system that is outside the local hard drive and is not impeded by Windows system caching. When you wipe unoccupied drive space, the process is run from the bootable CD/DVD operating system. Installed applications and existing data are not touched by this process. It processes all unoccupied drive space so that recovery of previously deleted files becomes impossible. Wiping the logical drive's deleted data does not delete existing files and folders. While you are still using your local hard drive, there may be confidential information available in these unoccupied spaces. You may also have deleted files by using the Windows Recycle Bin and then emptying it. You may have confidential data on your hard drive in spaces where data may have been stored temporarily. 1.2 Wiping Confidential Data from Unoccupied Disk's Space
