[QUOTE="secondshadow, post: 35366"] If this is indeed the case then perhaps the mechanism by which the HFS+ filesystem deletes files should be evaluated. I've never heard of something like this happening before. The next section can be ignored < rant > And as for the deletion thing, thats actually only partially true. The filesystem marks it as unused. I have actually used a filesystem configured in such a way that it overwrites any file that is deleted with zeros for security reasons (this was a custom filesystem built for linux) and as such the data was indeed removed and became, for the most part, unrecoverable without the use of rather expensive equipment. This is a common myth about harddisks and the way they work. </ rant > Sorry about that, its just one of those misconceptions that keeps being perpetuated that really bothers me sometimes. [/QUOTE]
