The pre-clear is still in progress, now onto the post-read. The disk is not in the array, it's unassigned devices and the disk info label is not clickable.
Pre-clear preview as currently stands below
Disk log
diskinfo_log also attached, which shows lots of entries where SMART info is not being found.
Should I pause the pre-clear to run a SMART test? No SMART info seems to be available below. I'm also sure I added the, manufacture and purchase date and warranty period information to the disk yesterday, parhaps when pre-clear was already in progress.
