Hi,

I've got a 3530 shipped with a NVMe SSD (hynix PC401, m.2 2280 512GB). Now I'm trying to install a second SSD (a Transcend m.2 2242 512GB) in the WWAN socket.

The BIOS/UEFI finds and shows them both fine. All SATA, mSATA, etc. stuff is enabled there.

However, Windows 10 doesn't see the second drive. Not in Disk Management, not in Device Manager (there's no unknown device or something either, Scan for hardware changes does nothing).

I would welcome any tips to get it working. Do I need to install any special Windows drivers for the second SSD? Registry hack? Witchcraft? Or anything obvious might have slipped my attention?

(As a side-question, the UEFI shows options for 6 SATA drives and 2 NVMe ones. Where can I connect at least one extra?)
