Wipe Disk and Disk Writing

Yesterday I ran Disk Wiper about halfway through its default settings, before having to abort, on a 40GB drive virtually all the files had been deleted from. Today I decided to pick up by just writing random numbers for two passes, not 1s and 0s. When completed, the stats showed about 105GB written. Where did the extra come from?

It will answer your query....

Best wishes,

Did you mean the comment of the JV16 Developer that the setup is misleading? I'd agree with that. 2 passes x40GB (max) shouldn't equal 105GB.

Could you please tell me what exactly did you do with the Disk Wiper? For example, did you use it to wipe free disk space or all data etc.

- deleted all files except one folder with 212mb that gave a message that it was still in use, and emptied Recycle folder.

- Ran Disk Wiper halfway through per bar indicator on default settings (1 pass 1/0s, 2 random) before aborting.

- Later, deleted 212mb folder, at least still nominally there per Win Explorer

- Changed Settings to 0 passes 1/0s, 2 random

- Ran Disk Wiper

- stats said 104.9x GB at completion

What operation mode of the Disk Wiper did yo use? The wipe all data, the wipe free disk space or wipe entire disk?

The default is wipe only free space. It's hard to believe I didn't change that, but I don't recall. At the end, the one folder with 212mb that I started with was still there, which surprised me, but as I vaguely recall now it was empty (or at least didn't resist being deleted this time). I could delete the jv16 created .dat file and try again to see what happens. Does the app log its stats somewhere for checking later?
