Red light mystery

Hardware and peripherals SATA HAT

When the red light came on, it was the chip that found the error in the hard drive.

Some of the errors are not fatal and will not affect your files, so it works fine for now.

You can use smartctl to check the hard disk information, but you need to do two things before that.

  1. Download smartmontools-7.1 and compile it. The version in the apt is too old.

  2. Upgrade the firmware. The factory firmware shows something wrong with S.M.A.R.T. .
