adrifromhh Posted February 10, 2021 Share Posted February 10, 2021 Hello guys, I am testing three 1TB drives, if they're still healthy to be used in an Unraid array. I'm preclearing them with the gfjardim Preclear plugin. Post-Read verification failed on a few runs. To speed up the process, I skipped pre-read after the first time. (Does it matter?) I already checked the SATA cables (all new) and swapped disk positions. Also I'm wondering if the power delivery to the drive cage is sufficient, but I dont think this is very likely. The current pending sectors returned to 0 after the clearing cycles. After the second Preclear cycle I started another round of extended SMART tests on the drives which exited with some errors. I'm running Memtest right now. I'll update about the results after some time. A summary on the tests: +-------+----------------+----------------+----------------+----------------+---------+ | Drive | S/N | Preclear 1 | Preclear 2 | Preclear 3 | SMART 3 | +-------+----------------+----------------+----------------+----------------+---------+ | 1 | JP2940J8046DTV | Pass | Post-Read Fail | Pass | Pass | | 2 | S1Y5J90SC63261 | Post-Read Fail | Post-Read Fail | Post-Read Fail | Pass | | 3 | S246J9BZ616699 | Disappeared | Post-Read Fail | Post-Read Fail | Fail | +-------+----------------+----------------+----------------+----------------+---------+ SMART Reports (after 3rd Preclear run) S246J9BZ616699 - Error JP2940J8046DTV - Passed S1Y5J90SC63261 - Passed Attached screenshots: Preclear Logs after the last round I'm still new to Unraid and SMART reports and would like to understand better what these results mean. I appreciate your help a lot Quote Link to comment
