That’s good; we can do with more help from knowledgeable WD staff.
How can I make such assertive statements? Because I know what the firmware is doing and what is not done by the firmware
Again, it’s good to have someone who understands how the firmware works.
But, again, I’d encourage you to look around the forum, where you’ll find plenty of examples of where the firmware quite clearly doesn’t behave as intended (unless the intention was utterly mad).
Did you write the design specification?
Did you write the Linux OS and packages the firmware relies on?
Did you write some of the code?
Did you write all the code?
Did you test all of the code in all possible configurations, with all possible environments?
If you didn’t, then you can only state with any certainty what the firmware was intended to do, not what it will do. And, even if you did write all the code, in systems as complex as the MyCloud, I think you’d be pretty bold to say you understood every aspect of its operation.
I too have been in engineering for a long time (32 years working as an electronic engineer for the research division of an international electronics company), and I would never say with that degree of certainty what my designs will do. I would only ever say what ‘they should do…’. And, despite that long experience, I sometimes struggle to understand how the WD apps are supposed to work. Which isn’t helped by the Help not being updated to reflect the changes for OS3. So heaven help those who don’t have my technical experience.
If teh manual states to do backups, then it’s because we want to take
care that nothing serious may happen. I am in IT for a long time, so I
have seen a lot of things happening that are mainly related to work that shouldn’t have been done
This appears to be an acceptance of what I’ve just said; things can go wrong. Folders can disappear. Folder permissions can be set incorrectly. The Twonky ‘integration’ is a good example of where I’m sure no-one actually designed it to interact so poorly with MyCloud; that’s just how it came out with the limited engineering effort available to do the half-arsed integration job.
Maybe it’s a language issue, but bold statements of fact such as ‘the folders have not disappeared’ when you have no evidence to support this, other than what should have happened, rather irritate me; it comes across as arrogance: “you stupid user; how could that possibly happen?” And I’m sure you don’t want to give that impression to your customers. Do you?
