X399 Taichi SATA HDD not recognized anymore

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,
I recently put together my X399 with AMD Ryzen 1920x. I have 5 HDD total. The bootable is a Samsung 860 Pro, 2are Samsung 850, 1 WD Black Caviar, and another something else.

When computer first turned on a small puff of smoke came out and smelled like burning hair. Well I though oh no the driver burned up, however, the computer booted up like normal and windows loaded. I reset the computer and it booted fine except 3/5 hdd were missing. I reset and now all 5 are missing. I grabbed my old sata cd rom plugged it it and it works fine. So the question I have is what may have caused the hdd to fail like that. How do test the hdd to see if it is dead? Do I hook it up to a voltmeter? 

Thank you in advance for any thoughts or help!

Patrick

	Well apparently when I turned on my power supply, a Corsair 850, it literally fried my 2 physical disk drives. I sacrificed one SSD to see if it was fried but all the chips looked fine. However none of the ssd will work so i think all 5 are toast.

	The mobo chipset/southbridge might be fried too, if some of the SSDs managed to 'leak' some overvoltage/overcurrent towards it, hence the rest of the SSD appear as not visible. Although, all SSD are under the same PSU rail, so if it was an OV, most likely all of them are toast. If I were you I'd contact Corsair for a damage reparations.
