Re: [Trisquel-users] How to clean the entire disk with Trusquel? USA and Russia FBI spy my PC

That's correct, from what I've read on the subject: a single pass will do the  
job, people apply more than one pass in case the first one omitted something.  
Fact is most agree on one thing: it is impossible to recover data from a hard  
drive after one pass, provided it was applied correctly. The 35 passes to  
wipe a disk is an old myth and it has to do with old technologies on which it  
made some sense. This is no longer the case with the modern hard drives (last  
20 years as the excellent Jxself pointed out).

As far as solid state drives: AFAIK wiping those is impossible and the only  
thing that can give you peace of mind is: FDE (full disk encryption).
