I am hitting a brick wall with my MISTer. I have had problems getting an external hard drive (a WD Black 5TB external USB hard drive: https://www.amazon.com/gp/product/B07VNTFHD5) to regularly be seen by my MISTer. Sometimes it sees it, sometimes not.
In an effort to get around this I picked up an external SSD (Crucial X8 4TB Portable SSD https://www.amazon.com/dp/B0B787PNL7). It is exFAT formatted (as is the WD hard drive) and is recognized by my PC. I copied the entirety of the files from the WD to the SSD. But every time I try to run a game that is stored on the SSD the screen goes blank! I don't know what to do about this.
Previously, while using the WD hard drive I made some efforts to get that to work regularly. I picked up a couple of USB splitter power cables: Cable Matters Micro USB 3.0 to USB Splitter Cable (USB Y-Cable, USB Y Cable) 20 Inches https://www.amazon.com/dp/B00L1K1OIA from Amazon but the external hard drive often does not read from the Mister. I thought the drive needed more power to run properly, but no luck yet.
I even got the MisterAddons MiSTer FPGA DC Power Jumper also in hopes that might help. But that didn’t help either. At least the build looks cleaner 
I can really use some advise on how to fix what I am doing wrong!! HELP!!
