CCleaner. HERE

Free to download. Incorporated into the software is a "Drive space" wiper. Do a normal "format" drive - then use CCleaner to wipe free space several times.

Tonnes of info available on Google: techworld.com/sec…10/

Disk Wipe sounds good. I used to use BCwipe a long time ago. All straight forward to use.

All the best, Phsy.
If you reformat it (even if not using the MS-Windows "Quick format" option), then it is possible to recover some (if not all) of the data using dedicated techniques.

A better option would be to delete the primary partition (& any secondary/tertiary/subsequent partitions), then create a new single partition but, again, this is not 100% effective.

You could, however, use one of the methods summarised within the link below:

thanks for advise. i try both way.
If you have a bootable USB stick with Ubuntu lying around, just boot it up and do something like shred -v -n 3 -z /dev/sda

No need to worry about partitions and ineffective formatting, as this will write random 1s and 0s over the whole disk 3 times, then fill it with 0s.

Yeah DBAN seems to be the one most people recommend.

For ref: do whatever you want with partitioning and reformatting - multiple times if you want - but if you don't physically write over the disk contents the non-overwritten data can be recovered.

Defibrilator eh? Nice. Hacker style. Of course, you could always bung the drive in the microwave for a few minutes too...

Belt AND braces. Me? I have a cordless drill on constant standby. Straight through, baby. The only thing my hard drives will be good for is draining pasta!
