注意

The sata interface does not support hot swapping. Please do not install or uninstall the hard disk when the power is on. Installing and uninstalling the power on may cause a short circuit of the board. At least the protection of the board will shut down, and at the worst it will damage the interface of the chip or burn the chip. To install the hard disk, you need to pay attention to installing four screws to fix the hard disk.
