Hi all,
Recently replaced a 4TB WD Green with an 8TB Seagate, the data rebuild has so far taken 2 days and is 67% done. This seems to be taking far longer than other posts on here suggest it should. Although I didn't use the preclear utility to test the drive, I did run 3 extended tests in Data Lifeguard before swapping the drives. SMART data is as follows (full report from diagnostics attached):

Several of the error attributes look sky-high, but I believe this can be normal for Seagates...
Thanks,
