SATA hotplug not working?

[JPT223]

Hi,

I set up a NAS but I realized SATA hot plug is not working.
Is it a limitation of my SATA adapter or doesn't it work in general?

Looks like I got a ASM1166 chip, but this is odd because the chip got 6 SATA lines but my card has 8 sockets.

this adapter is not optimal because it uses only 2 PCIe-Lanes.
I probably should by a new one. it was cheap, though



thanks
