Susanto,
Where did you get the ST8-U5 and the Card.
Please make sure the 1222X card is loaded with the latest firmware.
We also need the serial number, HDD model number and firmware version.
I just discuss with Areca, you can turn off NCQ.
Go to GUI (https:localhost:81) or go to MRAID folder and launch ARCHTTP
Default user name: admin, password:0000
Then go to System configuration, then disable NCQ.
In the mean time, Areca is working on a firmware fix for this issue.
