The hard drive seems to be deteriorating. Check its SMART status with crystaldiskmark; it looks likely it won’t hold up. If the information matters, disconnect it right away to avoid more damage and bring it to a data recovery expert. Many offer free assessments. The NAS is over a decade old, so restoring it probably isn’t worth it. Also, it appears the OS is stored on the drive itself—without it, the system won’t start, and reinstalling it isn’t straightforward.
I attempted SMART monitoring with crystal disk info; only the bad sector count showed up as 1. Now the PC doesn’t seem to recognize it no matter what I try. My next step is to let it warm up a bit so it might be detected, possibly because that’s why it was found earlier. Not really focused on the NAS, just the HDD. Apparently the HDD is formatted with ext3/4 (based on old forum discussions, which are now inaccessible), so it should at least be noticed. In the worst case, I’d consider sending it to a recovery service, but I’m unsure what options are available.
