smilenkovski Posted June 13, 2020 Share #1 Posted June 13, 2020 After my WD HDD reporting bad blocks very often, I decide to replace with Ironwolf 8TB drive, I had a spare sata and bought two Seagate Ironwolf disks.. I have backup of my files and start from scratch. Installed dsm 6.2.3, made a pool , volume. Dsm start Parity consistency check and I ' ve got this message several time: An unknown error occurred, so hard disk 1 was restarted. If you often see this message, please disable disk write cache. on both disks. After disabling the write cache there are no messages, but after reading here and there I think that that is a no way to go. Any advice?

Mary Andrea Posted April 30, 2021 Share #4 Posted April 30, 2021 I've got the same error (warnings that Disk x had to be restarted due to an "unknown problem" and it is suggested that I disable write cache). New! Disk IronWolf 4T running on raid. Every time bad sector, but I tried out NAS and HD works perfect, so its a NAS Xpeno malfunctinon (xs3617). I had to replace an New IronWolf for a Old HGST that works (warm) but perfect. Ironwolf ever never. Quote Link to comment Share on other sites More sharing options...
smilenkovski Posted April 30, 2021 Author Share #5 Posted April 30, 2021 In my case it was a cable problem. Now I have 3 Ironwolf 8TB, no complain. Quote Link to comment Share on other sites More sharing options...

smilenkovski Posted November 28, 2022 Author Share #7 Posted November 28, 2022 It was a year ago and I don't quite remember. But I am sure in the past two decades disks I've lost are lost by bad cabling. Actually, problems occurs when you close the back side of the case on a bad engineered cases.
