external SSD drive is not recognized by steam deck

[Yamazuto]

I have a little broblem with my Steam Deck: I'm not able to plug in an external SSD. It is simply not recognized by the steam Deck, even in Desktop mode. I actually tried two SSDs: A SanDisk Portable SSD 1 TB and a Sandisk Extreme Portable SSD 1 TB, also with different cables: Nothing. Any suggestions, someone?

Are you attaching the drives via dock with SD charger brick? It might not be getting enough power.

If thats not the issue it may not be auto mounting.

Do the drives show up in Partition Manager?

Also in Desktop mode, there are setting for external drives; auto mounting, ect.

Try booting into UEFI/BIOS by shutting down the Steam Deck; then holding the Volume + button and then pressing the power button.

In UEFI find the settings for the USB mode and try changing it from DRD to xHCI

Hey i just want to say thanks for this! I was going crazy trying to get it to recognize the same SSD the OP has.. shame we have to do this. Shouldn't it just be plug and play?

What is the model number for your san disk portal drives?

it's a bug in the BIOS, valve made xHCI the default while it's broken, why was yours still at DRD?

Isn't the XHCI a beta update? Valve has been slow pushing out stable updates.

I know the thread posts are older. But i have a possible solution.

You have to format the drive with GPT Partition instead MBR.
In my case my external SSD was not recognized (Crucial X9). After installing Windows with Rufus (GPT with UEFI without CSM), my drive was recognized. Maybe this is also important for internal SSD drives.

I would find that strange because anything under 2 TB is fine

This is also strange to me. SD-Cards and USB-Sticks are working with MBR. I‘ve tried many Drives (SSD 256GB-1TB), Cables and Hubs. None of them are working.
Maybe this is a Bug in Bios?

Check if there's a short in one of your cables. I have my HDMI shorting the 3rd party hub and the monitor. I never had issues with it unless i plugged in 1TB Sata m.2 from my usual 256gb NVME (plugged in the Hub).. kinda strange but the issues gone, and i need to get a new hdmi cables :/ hoped this helps other people
