thank you both so much, i can't express how happy i am. glad to be a part of unraid! after switching those ports to SATA it mounted no problem. can't wait to learn more from you all!

i'm very new to unraid (7.1.4). i've never built a server and i started by taking my old PC and adding 3x 4TB seagate drives. everything was working perfectly for 4 months. i recently purchased 3 more of the same HDDs and went through the disk clear and mounting process. one of the drives mounted fine and was added to my array without issue. the other 2 drives did not mount and say "unmountable: wrong or no file system". i've tried reseating sata cables. i've tried switching power cables to the drives (i have a 2 port power cable and a 4 port power cable) thinking that there was a power sag or something. i'm very much at a loss and don't really know what i'm doing, however prior to having my server running successfully for the 4 months i went through a lot of troubles that i was able to figure out on my own. this issue has caused me to come to you all hoping i can learn more and figure this out. please excuse me if my post etiquette is off or if i get confused, i promise i'm not here to waste anyone's time hahaha. thanks in advance! below is a list of hardware stuff and my diagnostics folder. motherboard: Gigabyte Technology Co., Ltd. 990FXA-UD3 cpu: AMD FX™-8350 Eight-Core @ 4000 MHz ram: 8GB DDR3 HDD: ST4000VN006 PSU: corsair CS650M tower-diagnostics-20260314-2337.zip
