There are numerous disk health check programs available for free that are quite good at detecting the health of storage devices, but unfortunately they do not account for bad connections. For example: you can have a HDD that is in perfect condition, but randomly disconnects periodically due to a bad SATA cable, USB cable, or just because the cable needs reseated.
If your storage medium passes disk health checks, but programs running off of it seem to be crashing but not when ran off of your primary storage device, this program may help identify if you have a bad connection.
In the case that you do, it's recommended that you first try reseating any connections (unplugging and plugging back in again), and if that doesn't work, replacing any cables involved or trying a different port.
This program requires Java (it was built using OpenJDK Runtime Environment build 13.0.1+9, but likely will work on Oracle and earlier versions of Java).
Once installed, you just have to run the .java file and follow the on-screen
instructions.
