Roxas112 said: I have similar problem as the original post. I cannot find my 3 HDDs after replacing a faulty PSU, not in Disk Management nor in the BIOS. What it does register is the CD/DVD drive. I swap the SATA and power cables from the CD/DVD drive to either of the 3 HDDs, it does not work. On the other hand when I used the SATA and power cables from either of the 3 HDDs and hook it up to the CD/DVD drive, it can be detected. Right now I am waiting for a SATA to USB cable to test whether I can detect the HDDs on another computer. I just want to see if there are solutions to this problem.MBD : MSI Z270 Tomahawk opt boostCPU : intel i7 7700KGPU : EVGA 1080 TiRAM : G.Skill Ripjaws 2x8 GB DDR4-3200Old PSU : Corsair CS850M 80+ GoldNew PSU: EVGA 650G+ 80+ Gold
TSTonyV said: You've switched your PSU, and I doubt it's a board issue if you can detect your DVD drive, but it's hard to say 100%. Do you have another system you can try plugging the drives into to rule them out as a potential issue? While it's very unlikely, if the drives were sharing a power cable that was separate from the DVD drive, the faulty PSU could have damaged those drives while the DVD drive was left unscathed.
TSTonyV said: Based on all the steps you've gone through already, I'd actually say that we haven't ruled out the PSU as an issue. The CPU doesn't really have anything to do with detecting SATA devices on your system, that's handled by the chipset, and you've already ruled out the motherboard as a potential culprit. I'd say the most likely culprit is a bad SATA power cable/rail on the PSU. The power supply you have should have multiple SATA power ports on it, I would try different ones to see if that fixes it, and if you have a spare SATA power cable, try that as well. If neither of those work, try swapping in the Powerspec PSU from build 2 into the main build and see if that fixes it.

I got the SATA to USB cable (https://www.amazon.com/gp/product/B07PVX682Q/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) and tested the 3 HDDs. Unfortunately, none of them are able to connect to my laptop. Just to be sure that the cable is fine, I pulled out one of my 2.5 HDD from my external drive and test the cable. My laptop was able to read the 2.5 HDD just fine. Looks like my 3 HDDs are dead. Stupid Corsair PSU, I will not buy Corsair product again.
