Help deciphering the preclear report

Featured Replies

Finished building my first unraid server and preclear on the 3 HDDs. The HDDs are all new for this build and have a pass, it is all the extra info I have no idea what it means.

I've included the first HDD report.

I would greatly appreciate any help.
