Thanks for the fast reply

Hi together, I bought a used SAS drive and actually I do a preaclear. But I sea some attributes in the smart error log which I don't know. HBA: LSI 9400-16i HDD: HGST HUH721010AL4200 10TB Manufactured 2020 Accumulated power on time: 3566 (4m, 25d, 14h) What I see in the SMART error log: I'm not sure if the delayed read and verify errors corrected by the ECC are a problem or not? Should I add the drive to my array or not. Actually it does the Post-Read, the values increased during the Pre-Read. sg_logs.log

@amiga4ever Wenn du den zweite Container erstellst, hat er dann zufällig die gleiche IP Adresse wie der vorherige und läuft parallel? Normalerweise sollte es funktionieren. Hab damals mit Andre das Verfahren zum direkten einspielen eines Backups unter Unraid entwickelt.

Funny thing, I think about the same solution at the moment and the prerequisites are the problem I have too

Hi Joe L. thanks for the response. I use unRAID version 5.0.5 32bit The disk didn't respond to any smartctl command after the preclear ended with this message, it's completely un-responsive. I tried a dd to clear the mbr, that worked. After that I tried it with more then 1024 bytes and it crashed so I'll return that drive because I think it's bad. Testing in 2 other systems reproduced that error so the disk controller of my unRAID Server cannot be the problem. Duff

Hi togehter, I have new 4TB disk and tried to preclear it in two different servers.

Hi I had to format one of my 2TB HDDs with NTFS. Now I want to preclear this disk again before I assign it to the arry. Is it possible to preclear the disk without the pre-read(-W Option) because I know the Disk is Ok and I want to save Time?
