New NVMe SSDs are not partitioned and will need to be both partitioned and formatted when first connected to the Raspberry Pi before they will be accessed in the Explorer.
树莓派系统配置
Enable the external PCIe port on the Raspberry Pi 5. Edit /boot/firmware/config.txt and add the following at the bottom:
|
1 2 3 4 5 6 7 8 |
# Add to bottom of /boot/firmware/config.txt dtparam=pciex1 # Note: You could also just add the following (it is an alias to the above line) # dtparam=nvme # Optionally, you can control the PCIe lane speed using this parameter # dtparam=pciex1_gen=3 |
