Windows 7: Reformat and secure data deletion

Reformat and secure data deletion

I erased the old Windows XP partition and created and formatted a new one, and reinstalled Windows XP. All this on a machine I want to sell. Does this securely erase data I previously had on the hard drive? Thanks.

No, you need a "wipe" utility to overwrite all free space.

Do a search as there are many free utilities to do this. (It helps to delete cache and temp directory files, empty trash, then defrag before running the wipe utility).

I don't think you need a 3rd party app. Following Bare Foot Kid's excellent tutorial using the diskpart command should sort you out.

Also see Microsoft's page for extra info.

Thanks for remembering that - old habits die slowly...but does the XP version have that switch?

The link above seems to say so.

Hmmm. Would wiping the free space with CCleaner do it?

Not CCleaner, use free Partition Wizard bootable CD if you need a GUI.

Otherwise boot the WIn7 DVD or Repair CD, press Shift + F10 at first screen, type in Command Box:

DISKPART
LIST DISK
SELECT DISK # (use target HD #)
CLEAN ALL
EXIT

Takes about 1 hour per 300 gb to write zeroes to entire HD.

Are these directions the same for an XP machine?

DISKPART will work, but if you want something else as an alternative, DBAN is a very small, but effective program that you download in the form of an .iso file. You'll get choices as to the level of over-writing/wiping you can achieve.
