I have a brand new 2T external Samsung SSD disk. (two of them) for backup.

I tried the first one and had an issue, I tried the second one and got the
same issue.

Am I doing something wrong ? I find it hard to believe the SSD (both) are
bad.

I plugged in the USB 3.1 adapter, I fdisk /dev/sdd, n, p, default, default,
w.
then mkfs.ext4 -j /dev/sdd1, then just mount and rsync.
