HDD GURU FORUMS

Hi there, several of these programs appear to do the same thing(s)... what are the differences between the following programs? Is functional overlap between them due to the guru starting work on a newer app and then just abandoning the older apps? If so, which of them are actively developed and 'current'?

- Wipe My Disks
- HDD LLF Low Level Format Tool
- HDD Wipe Tool
