I just went through 6 years of a syslog file and there wasn't anything mentioned about /dev/sda, /mnt/flash, or 
anything else that indicated that something was wrong with the disk or the filesystem.

RANCID was even showing that there were EOS image files there that weren't actually there when it was backing up the 
configs and the startup-config date showed 2/28/2025 until the system was reloaded and then it began saying 
startup-config was actually last written on 03/11/2022.

RANCID shows that there have been 57 configuration updates since 3/11/2022 and every time 'write memory' was run it 
said: : “Copy completed successfully.”

Anyway thanks for replying.
