June 6, 20224 yr I moved my all my drives to a new system two days ago and have been pulling my hair out because 4 of my 8 Data Drives were not coming up. To make a long story short, the Power cable connector on the New Power supply I bought was wired incorrectly on one of the Pins and it appears to have fried the last 4 drives from my array. Both Parity Drives, the 4 Cache Drives, and the First 4 drives in my array are all good. with the loss of the last 4 drives in my array, I would like to know if there is any way to reserect the Server with everything that was on the first 4 data drives drives and simply add 4 new drives the last drives and restore data??? My dockers, apps, etc are all on Cache or the first four drives. Let me know please!

Pls check does relate disks not like 3.3v pin issue. 8 hours ago, Shesakillatwo said: there is any way to reserect the Server In tools - new config - Preserve current assignments could help you, it will retain the disk info to minimize manual assignment or mistake. https://wiki.unraid.net/Manual/Storage_Management#Reset_the_array_configuration To summarize, just don't wrongly assign data disk to parity then you won't lost data. You can rebuild parity and add new data disk in same time or different time.
June 7, 20224 yr Author Thanks for the response. I purchased this power supply to use: https://www.amazon.com/dp/B09BNBWSWJ?ref=ppx_yo2ov_dt_b_product_details&th=1 And an extra pair of Sata Cables: https://www.amazon.com/dp/B09BN49K96?psc=1&ref=ppx_yo2ov_dt_b_product_details How I identified the Problem is on the Connectors that attach to the Power Supply there are 5 wires on each, but of the six locations wire can be attached on those connectors they are diifferent between the two cables I ordered seperately and the Sata Cables that came with the power supply. Not sure just one pin is wrong or several (thay are all Black) but the connector plugs are different. When I removed these cables and conneted with Splitter Sata cables I could get new drives to be recognized. I also put the original drives in another Unraid server I have and none of the four were recognized..... I also found the Tools - New Config a few hours after I posted and I am rebuilding parity now. Hopefully all will work! Thanks again!
June 7, 20224 yr Community Expert FYI: There is no standard pinout for modular power supplies, so it is important that you always use cables that are specific to the model you have.
