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.
