Unbrick without losing data?

that’s not as painful as losing your data

3TB might 24/48 hours to do (8/16 hours of that you’ll be asleep for) which is nothing compared to the time you’ve spent filling up the drive and the time you’ll spend getting all the data back…

I would count yourself lucky you have an opportunity to recover your data.

Yep.

Unbricking the My Cloud you WILL lose your data doing it.

I’m sure if there was a way of doing that was not data destructive then there would be guides showing how to do it.

But if there is no other way … then that’s why it’s a last resort method.
