I was doing a battery backup runtime test, and the server ran for about 35 minutes but shut down abruptly (it’s supposed to shut down properly, as if you went and hit “shut down” from the Start menu), but no. It simply powered down. Turning the server back on brought me to a frozen BIOS screen and a hard drive making some beeping sounds and not spinning up.

Turns out it was the primary server operating system drive. Files were lost that were stored on this drive but at least the Minecraft files (and my home PC backups) are intact.

I’m currently trying to find a way to get back up ASAP but at this point things are bleak.
