[QUOTE="Digerati, post: 666372, member: 59833"] What is the point of this quote and in [B]bold emphasis [/B]no less? I never - as in [B]NEVER EVER[/B] said you should "wipe" a SSD. In fact, I repeatedly said you should [B]not[/B] "wipe" a SSD. And, sorry, but your link does not say, don't use Secure Erase on SSDs or that Secure Erase is "harmful" as you claimed. Your English is just fine. As is often the case, it is better than many who have English as their native language. It is your understanding of the technology that is lacking, perhaps causing you to assume too much. [INDENT]1. You are assuming all SSDs support TRIM. Not all do. 2. You are assuming TRIM is enabled, or has not been disabled. 3. You assume the SSD firmware is not buggy and TRIM and garbage collection function properly. 4. You assume all files have been manually deleted by the user before getting rid of the drive. [/INDENT] Now for sure, we are talking about using sophisticated forensic techniques to recover "court approved" evidence, sensitive data desired by bad guys, or the like. This is a much more complex process with SSDs than it is with hard drives. But because users wanting to protect their sensitive data cannot make those assumptions I noted above, Secure Erase is the only way to ensure SSD forensics cannot recover anything. Yet that is what you seem to expect. I copy and post (with links to the source) because I don't expect people to follow or automatically believe what I say. So instead I link to references instead of claiming my "[I]years of professional experience[/I]" is all the readers need to know. :rolleyes: So here is another link.
