Thank you for this. My discs get a clean bill of health from SMART. So I'm left with these hesitations I don't understand. These happen with simple bash commands (ls, man, mv) as well as delivery of web pages. For instance, I just waited nearly 30 seconds for "man" to return, but only when the given command has not been used for a while. Is there some aspect to disk access that SMART does not test? Thanks.
