Internal HDD in RockPro64 with NCP not available

Hello - I have a fresh NextCloudPi install on a new RockPro64 with SATA connected HDD. The available drives include my emmc, but not my HDD. The HDD spins and has tight connections. Any ideas what might be causing the no-read?

did you check that the disk is recognized by the operating system itself?

is it listed if you enter sudo lsblkid on commandline?

That’s correct. lsblk displays the disk drive named “sda”. But df -h does not list sda. Similarly, blkid shows the disk name, but not the UUID.

df -h can show only drives which are mounted and partitioned, independent if connected or not
