Re: "Low level format"
@ElReg!comments!Pierre: Also know to most techies as simply "format". There is no such thing as "high-level format". There is formatting, and there is deletion of the partition table. Microsoft's "quick format" is therefore not formatting anything. "low-level" format here would not be (more) indicative of deliberate mischief.
You don't know what you're talking about. Perhaps you should try using that new-fangled thing called Google:
Low-level format (LLF) -- https://www.webopedia.com/TERM/L/LLF.html
High-level format (HLF) -- https://www.webopedia.com/TERM/H/HLF.html
