UnluckyTech Posted November 22, 2021 Share Posted November 22, 2021 I have recently purchased a new Seagate IronWolf 10TB drive due to my server running low on storage. I presumed the next steps to adding the drive onto unraid would be to install the drive, format the drive, and preclear the drive. Anytime I would attempt to preclear (gfjardim - 1.0.22) the drive it'll show "Pre-Read: 0% @ 0 MB/s" and this is what shows in the logs...

Nov 20 21:53:15 preclear_disk_ZS512YZW_19855: error encountered, exiting... Also when I do the Script "Joe L. -1.20' it states... "Sorry: Device /dev/sdb is not responding to an fdisk -l /dev/sdb command. You might try power-cycling it to see if it will start responding." I initially thought it was a bad drive since I couldnt even load the drive when installed into my pc but this is the second drive now having the same issue. Model Family:n/a Device Model:ST10000VN0008 Serial Number:ZS512YZW Firmware Version:SC61 Size:10 TB This is my server ST10000VN0008_ZS512YZW-20211121-2248 (sdb).txt Quote Link to comment
JorgeB Posted November 22, 2021 Share Posted November 22, 2021 Looks like a drive problem, it's not even giving a valid SMART report. 1 Quote Link to comment

Frank1940 Posted November 22, 2021 Share Posted November 22, 2021 Get the Seagate drive tools (google to find the download site) and test the drive in a PC. That will test the drive out in accordance with what Seagate wants to see. (It also gives you leverage if you want to use a vendor exchange policy rather than a warranty exchange.) Two bad drives in a row is not what one wants to be a victim of. If true, it means you could be buying into a bad manufacturing lot... 1 Quote Link to comment
Frank1940 Posted November 22, 2021 Share Posted November 22, 2021 One more thing to consider is this problem. I have had heard of it being much of an issue lately but anything is possible... https://forums.unraid.net/topic/73717-solutions-shucked-wd-8tb-easystore-33v-pin-issue/ Quote Link to comment

Just thought I would comment on this since it shows a misunderstanding of "format". There is no point in formatting a drive before preclearing it since the format would be completely wiped out by the preclear. And if you format a precleared drive, then it is no longer clear since it is formatted. The most important mistake you should avoid is formatting a disk that should have contents on it. You can't rebuild a formatted disk from parity. 1 Quote Link to comment

UnluckyTech Posted November 25, 2021 Author Share Posted November 25, 2021 Yeah looked like I just had bad luck. I ordered instead this drive by Western Digital and worked the moment I plugged it in. Started the preclear and everything is running like it should. Quote Link to comment
