Secure format formatting time

Hello All,

I was wondering how long (in general) it takes to perform a complete secure format on a 4tb mycloud mirror. I started the secure format, and it has currently been running for 73 hours. Is this normal, or is there an issue with the drive? Thank you in advance.

Hi brainspasm, welcome to the Community. I haven’t tried this, on the manual it only specify this “Formatting your disk will take several hours to complete”. Maybe some of the other users can share some info.
