Mave Posted September 10, 2023 Share Posted September 10, 2023 (edited) Hello, Last week I put together my first build. i was advised to pre-clear all my disks. And so I started the pre-clear on all my 5 disks. So far one has failed. What do I do with the one disk? Is it bad for sure? Or should I attempt another pre-clear?

My biggest question is: Is there such a thing as false positives or not? I want to take no risks. If there is such a thing as a false positive, and a second pre-clear will confirm or deny, then I'll run it again. If there is no such thing as a false positive, I'll toss the disk now.

Thank you for answering. A second pre-clear finished without problems... The pending sector count went back to 0. Would you use the drive now?

That looks like a script issue. I'll have to spend some time on it. Can you post your diagnostics. I want to look and see if I can figure out where the 'magic8 corrupted' comes from.

My diagnostics will probably be useless now, since the script eventually crashed and had to reboot the OS. Have not had a chance to start the pre-clear again and would probably take around more than 24 hours to reach the step I was at unless I skip pre-read. I have asked around and someone thought it is a memory issue. Quote Link to comment
i1mran92 Posted September 21, 2023 Share Posted September 21, 2023 hi. been preclearing for the pass 2 days and so far everything seems smooth. just waiting it to finish 1 question, i was able to see detail stats before by pressing the eye icon beside the timer. its gone now. is becayse its in that stage and u cant see the stats? or there's some bug Quote Link to comment

It's probably a Browser issue. Try clearing the cache or try another Browser. You can go to the UD preclear page at Tools->Preclear Disk or the icon at the bottom of the Unraid webpage to see the status. Quote Link to comment

DevanteWeary Posted October 5, 2023 Share Posted October 5, 2023 (edited) Guys, I'm just supremely confused here. I just finished using UD Preclear and everything finished with no errors. So I stopped the array, added the drive, and started the array. I get the "Unmountable: Unsupoorted partition layout" message next to the drive and my storage has no increased. The instructions say no need to format, and several posts here give conflicting information. If I click the red X next to the drive, it tells me it'll remove the pre-clear signature and Unraid will start the lengthy preclear all over again. I've tried rebooting as well. I thought it was as simple as Preclear > Add to Array but seems I'm missing a step. What am I missing guys? Thank you! Edited October 5, 2023 by DevanteWeary Quote Link to comment

What am I missing guys? That you need to format the drive after adding to array, you should have the format button available at the bottom with the disk you added in the list on the left.

Hmmm I don't have any buttons at the bottom of Unraid > Main > Array Devices I do have a button under Unraid > Main > Array Operation called Format that says "will create a file system in all Unmountable disks" and when I click it, gives me the following warning: Format Unmountable disks Create an empty file system on the disks shown as Unmountable discarding all data currently on the disks and update parity to reflect this. This is typically done when a new disk is added to the array to get it ready for files to be written to it. **WARNING** A format is NEVER part of a data recovery or disk rebuild process and if done in such circumstances will normally lead to loss of all data on the disks being formatted. Think I should go ahead and do that one? Sorry, just trying to avoid another 4 day clearing. Edited October 5, 2023 by DevanteWeary Quote Link to comment

Worked like a charm. You're the best. 😆 Just throwing the steps here for anyone looking for a definitive order: Use UD Preclear on drive. (could take days) Stop Array Increase drive number by one. Select new drive to fill new slot. Start Array. Format drive through Array Operations > Format Done! 1 Quote Link to comment
jimeez Posted October 26, 2023 Share Posted October 26, 2023 I have never been able to get Preclear to work. It fails every time regardless of the disc.
