Software: DJ Drive Tool

Designed for Four Functions:

Verify Disk Integrity

Drive Tool will either scan or write test data to the entire surface of your disk to make sure that the disk is suitable for storing data. You can make sure your disk can be used to store data reliably.

Wipe Data from Drives

Drive Tool will overwrite your drives in up to three passes: two with random data, one with all zeros, to make sure your data can never be recovered. This is useful when selling or disposing of a computer or drive.

Recover Damaged Data

Drive Tool will make multiple attempts at trying to read data from damaged portions of a drive. Once read, the data is re-written back to disk so it can then be copied (manually) or opened in its native application.

Drive Performance Testing

Starting with version 1.3, Drive Tool records performance data as disks are being scanned. The results can be submitted to the DJP Card Database.


  • Fast! Large data buffers allow data reads and writes to occur much faster than other similar tools
  • Secure! Random data is generated using cryptographically secure generators
  • Flexible! One piece of software performs many functions
  • Free! DJP doesn't require any licenses to be purchased
