Do you have any "history" with the adapter you connected them to? If not consider it as a possibility as well (from bad experience of total filesystem/partition corruption on two hard drives only to discover it was something on the motherboard).

Subject: [EXTERNAL] CentOS 7.6 external USB dmesg issue
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.
