Thank You for the information @xabbu and @winnie!
After doing some internet searching of my own I found a post @ https://www.truenas.com/community/threads/seagate-ironwolf-smart-test-raw_read_error_rate-seek_error_rate.68634/ where someone posted an altered smartctl
command that gets you the “true” raw-read-error-rate
and seek-error-rate
values which indeed do now show 0

Also restarted the SMART Extended tests I aborted… and feeling much better with the knowledge you’ve both shared and the command I found.
EDIT:
Ah-ha, now I understand the why/how raw48:54
works… from one of @xabbu links…
The raw value of each SMART attribute occupies 48 bits. Seagate’s Seek Error Rate attribute consists of two parts – a 16-bit count of seek errors in the uppermost 4 nibbles, and a 32-bit count of seeks in the lowermost 8 nibbles.
So raw48
sets the proper data type and :54
focuses in on the “seek error” value in the “uppermost 4 nibbles” (discarding 3210
which represent the seek count)
Whereas the online calculator is likely doing the same thing, just showing the 54
and 3210
separated values individually.
Seagate super-packed the data! So unless a reported decimal number >= 4,294,967,296… an error hasn’t happened yet.
