HDD LED issue with PCIe M.2 SSD?

Hi everyone,

I changed my previous SATA M.2 SSD to a Samsung PCIe M.2 XP941. Some days later, I noticed the HDD LED doesn't blink.

It's not really a big problem. But sometimes, it's a good think to see the disk activity.

Am I the only one to encounter this issue? Is it a know issue?

Thanks in advance!
