Ah you mean /sys/block/sda/queue/rotational.
A few data points:
- Four rotational disks in my server are correctly reported as such.
- The rotational disk in my laptop is as well.
- The Intel SSD in my set-top box is reported correctly as non-rotational.
- However, the CompactFlash card in my broadband router is incorrectly
reported as rotational. I attach lshw for this system.
Cheers, Jan
