Hello,
I bought a rack-mountable case (unykach HSW4520, identical to the intertech 4u 4420). I have ordered two sff8087 reversed cords (https://www.amazon.fr/dp/B09BKMDK5Y?ref=ppx_pop_mob_ap_share).
But after multiple tests no disc is detected. I have test on two motherboard. Strangely enough, when a 3.5 inch drive is plugged in it won't boot. All 12v and 5v voltages are OK (even on a hard drive card). But if I start by making contact between pin 11 and 10 or 12 of the hard drives (cf schema of sata pin) , the drives start up, but still are not recognized. The ssd also does not work.
I did a lot of testing without results but I don't know what to do now.
Hope you can help me.
Regards,
Florian
