Internal Drives seen as Eject-able

I recently updated my system to Windows 10 Pro Build 1511.14. No matter what RST(station-master) I update with I see my internal drives as eject-able.

At one point, the controllers got messed up, was ejecting “NTFS” flash drive just after plugging in but my internal drive was working fine. Now, I re-installed windows 10 and installed the stated drivers at ECS’s support page, system is working fine but the eject issue remains.

System Information:
Motherboard Name ECS H81H3-M4
BIOS Type AMI (05/21/15)

I’ve also tried updating the MEI from the forum, running the latest 9.1.37.1002
And UEFI Bios mod as well, patched the rom with forum’s latest mods (v14 rst) and flashed it with /gan.

No luck.

PS: Thank’s for all the work here Fernando, really appreciate it.

@ Stryker:
Welcome at Win-RAID Forum and thanks for your report!

Please give us some additional informations:
1. With which SATA mode (IDE/AHCI/RAID) is your on-board Intel SATA Controller running?
2. Which Intel AHCI/RAID driver version are you currently running?
3. Are all internal disks shown as “Safely removable” or just those, which do not contain the OS?

By the way: The “Hot Plugging” ability of all disk drives (except the system drive itself) is a feature and not a bug.

Dieter (alias Fernando)

I am running them at AHCI. I only have 2 Hard drives, ADATA P600 Boot drive and Seagate SSHD 1TB.
