Using LithiumX:
Attached is a custom version of LithiumX is currently the only dashboard that can read and launch games/apps from both drives.
Existing Setup: Delete the E:\udata\lithiumx folder before using it for the first time.
File Lock: LithiumX will lock E:\udata\lithiumx\lithiumx.db while in use, so you can't delete it while it's locked.
Launching XBEs: You can launch any XBE from the Start menu (Utilities > XBE Launcher).
View Partitions: The Start menu (Utilities > XBE Launcher) is also where you can see all partitions from both drives if detected.

New to LithiumX?
LithiumX will scan for games/apps in configured folders (from both drives) and display them. Use the black/white buttons to switch pages.
Cache Management: Lith will cache the scan results for faster subsequent boots. Clear the cache from the Start menu (Utilities > Mark Database Reset at Reboot).
Config File: The folders to be scanned are stored in the config file E:\udata\lithiumx\lithiumx.toml.
