Yes, i just buyed via a reseller, new, in sealed bag. Myself i cut the plastic bag and put it in NAS. Drives was packaged in buble foil individualy and next both again packaged in buble foil and put in carton corugated box… I registered disks on WD and i have waranty of 5 years, expiring in 2028, so i am covered…

Yes, both disks are the same simptoms… I run some hdparm commands and i see this status at security… how new disk are locked status? even WD Dashboard on PC desktop indicate that both drives are Locked… i read about this and seems a lot of ATA commands are not permited when drive is in locked state… Mijzelf, thank you for…

Thanks for anwser! Yes, those drives are manafactured in two variants with 512 and 4096 bytes/sector… Outside of NAS i tested and is not detected by bios… Maybe my PC is to old… After a while appear at Disk Management with no volume and whan i try to initialize via GPT ends with error: «I/O error» or «Incorect operation»…

Thanks for anwser! I do not have a solution for backup almost 4 TB of data... I have a external 2TB drive and i copy the most important data and after that i try to change raid type... I hope works well...

Thanks for reply! That seems to be solution... I was expected once i created a RAID1 volume with 2 hdd of 4TB and after that by extended with another 2 hdd of 4 TB, the whole array goes to 8 TB mirrored on group of 2 hdd, not to remain at 4TB, mirrored on each hdd of 4TB... My bad... Seems to be true that limitation…

I think is doable in your configuration... On my NAS i created volume with first option Volume and then Raid1, not with Disk Group... So on Disk Group i do not have anything...

Thanks for answer! Problem now is on storage manager i do not have any options to manage/change something... Only Create or Delete... Searching of my problem i find something which i do not know if is relevant: "Your traditional RAID formats - 1, 5, 6, 10..all have restrictions In that you can't increase the array size…

Hello! I run into a similar situation... I have a NAS326 with 2 hdd of 4 TB in RAID 1 almost full (94%) and i buy another NAS542 and 2 hdd of 4 TB. I put NAS542 online with 2 hdd of 4TB in RAID 1 and copy all content from NAS326 via network. Until now all is fine, NAS542 is online with 2 hdd on RAID1 almost full (94%)...…
