Break Raid 1 into Single disks

[dandymanz]

Hi, i am now using the AS6404T model. And have Volume 1 running as Raid 1 with 2x HDD. I would like to break the RAID and leave HDD1 as Vol1. Then remove HDD2 for other purpose. However, i don't seem to find the option to remove Raid 1. When i take out HDD 2, it just shows the Raid is running in degraded mode. I seem to remember i could do this on an older Asustor model few years ago. Could anyone advice me how i can go about doing it now? Thank you.

You had done your request. Yes, your volume-1 should become degrade mode after you removed HDD2. You can use HDD2 for other purpose.
