November 21, 2025Nov 21 So I have this really weird issue.I recently went to swap my setup out with a newer one. During this process, half of my drives stopped showing up. Initially I thought it might the usual suspects, dead card, faulty cables, motherboard compatibility issue. But then I started thinking that none of that made sense because I still saw drives, then I had a thought: which drives are not showing up? And I noticed a trend, they were all my white label drives (WD140EDFZ, WD140EMFZ, WD120EMFZ and WD80EMAZ).So I took the drive out, made sure the 3.3v mod was still good and put the parity into a new system and it came right up when I went to disk management, ready to be formatted.Then I took a WD Blue 4TB drive and put it in the same position the white label was in, and that drive popped right up in unassigned drives.I also bought new cables for my LSI and Expander card and still the same thing.So I'm at my wits end trying to figure this one out. I've attached the diagnostics. brashear-diagnostics-20251121-1823.zip
November 22, 2025Nov 22 How do you know your 3.3v mod is still good? Does the system you tested with use the same power supply as your new setup? Do you have a molex to sata power adapter you can test with in your new system?

I'm pretty sure I just killed the remaining drives I had showing. brashear-diagnostics-20251121-2143.zip Edited November 22, 2025Nov 22 by DevyNotDev
November 22, 2025Nov 22 It is highly unlikely that using a molex to sata adapter killed anything. Something else is wrong.If you have another way to test each of the drives, that will tell you for certain if they are dead or not. I keep a usb dock connected to my regular pc that allows me to quickly determine if a drive is (most likely) dead or not.
November 22, 2025Nov 22 If you confirm disk can't detect anymore, pls check does the protection diode in short circuit. This need some electronic skill.Those are one of common hardware failure and easy to fix.https://community.spiceworks.com/t/identifying-location-of-tvs-diode-on-wd-gold-hdd/799956
November 30, 2025Nov 30 Author Hello all!Posting an update so we can close the thread, but I've rebuilt a brand new system and tested drives that weren't apart of the array I was running and they came up just fine in the new system. But when I put any of the drives in the new system from the old system, it was cold to the touch, with no kind of activity.The molex splitter that was in original system did not work with the new drives in the new system. I pulled another molex splitter from another system and it worked in the new system.So I say all of that to say that what more than likely happened was a power surge and I fried all of my drives during the upgrade.Thanks to all that tried to help me out!Time to start from scratch!
