perfect Posted July 14, 2023 Share Posted July 14, 2023 (edited) Hi! I posted a very similar issue yesterday and I thought I solved my problem.... maybe not. I purchased a few 10TB HGST UltraStar HDs (https://www.amazon.com/dp/B07DPKWLJR) that were used from a datacenter refresh. I already replaced my main parity drive (a 3TB WD) with one of the 10TB HGST datacenter drives. At first I couldn't get the 10TB HGST to appear in the system until I used the supplied "power disable" SATA adapter cable. This worked for my parity 1 drive and I was able to upgrade the parity drive. Today, I tried doing the exact same replacement procedure for my parity 2 drive (currently a 3TB WD) with an identical 10TB HGST datacenter drive. Of course, I first tried using the "power disable" SATA adapter cable - but unRAID didn't see the drive. I have since tried all sorts of combinations of SATA cables, HBA card ports, power cables, mobo SATA ports, different 10TB datacenter drives, etc. No matter what I do it doesn't seem to want to find the 2nd 10TB drive and I'm stumped as to why. If I plug in the 3TB WD it immediately recognizes it (as an unassigned device). Note - I can physically feel the drive spinning up (while using the "power disable" SATA adapter cable. What should I try next? I'm following this procedure here: https://flemmingss.com/replacing-a-parity-drive-in-unraid/ I've attached my diagnostics if that helps! renfrewnas-diagnostics-20230713-1958.zip Edited July 14, 2023 by perfect Quote Link to comment
JorgeB Posted July 14, 2023 Share Posted July 14, 2023 Try that drive with the same cables/port being used by parity, if it still doesn't show up it may be bad. Quote Link to comment
