I am running XP. I have an external storage disk that I have had for years that I am now planning to donate. Trouble is I have had financial stuff stored on it and I am worried that it could be retrieved by others I have also used it for back ups and there are files on it that are still there, even after formatting. I have had a trawl around the various posts near to this topic and people seem to have various views and favourite software to do the job. Is there a recommended way of getting rid of ALL files on such a drive? Ta.
