running ROMS from external drive (exfat)

EctoOne

Are you using an external power supply for your drive? Otherwise it might be that it doesn't get enough power through the pi.

kombat

@ectoone yeah both 3TB drive have an external power supply. Retropie must be recognizing the drive as I can see it mounted in the web interface for retropie manager and I am able to add roms that way, they just dont show up when I reboot

EctoOne

@kombat do you have gamelist.xml files either in your rom folder or wherever emulationstation puts them by default (can't remember nor check right now what the default path is)? If not, you might have set emulationstation to parse gamelist only.
Otherwise I have no other idea of what's going on. I'm only using a 128 GB stick, not a drive.

@ectoone I think I have narrowed it down to a size issue. 500 gig and 1TB drives both work, but the 3TB does not. Testing out a 2TB tonight.....

Is it possible you need different drivers for it?

@hurricanefan I've been able to make exfat work with drives up to 2TB without a power supply, but 3TB with a power supply don't work so I think its a size limitation perhaps

I have an 4TB drive without external power supply, formatted as NTFS, and the ROMS show up in the retropie menu correctly.

The only issue I see is that it doesn't show the ROMS when I first power up retropie, I always need to restart ES once for the ROMS to be loaded, but I don't if that is normal or not.

4TB is a large drive, I think the mount operation - on start - takes a long time and it's not complete when ES starts up.

@isrnick interesting I am going to explore down this path thanks isrnick. May I ask what method you use to restart emulationstation. Command line?

kombat

@mitu I am able to see the drive in web manager and able to upload roms successfully if that counts for anything. They just never show up in the menu. Also have confirmed this is the case for both fat and exfat. Have tried with 2 different drives as well to confirm its not the drive causing the issue.

Restart es, check parse gamelist settings.

That certainly would explain it, thanks.

No, I just press Start and go to Quit > Restart Emulationstation.

No, I just press Start and go to Quit > Restart Emulationstation.

This worked! Thanks and thanks all for your suggestions and help

This helped me at least to mount my stick under Raspbian Stretch. Now i can start using ScummVM 2.0.0 and don't have to wait for Retropie to update.

If that is the case, is there some way to delay ES' start up during boot? It would take longer for the system to load completely on boot but I have to restart ES every time anyway.

@isrnick Modify the autostart script (from /opt/retropie/supplementary/ .. somewhere) and add a sleep X (X=nr. of seconds to wait) statement before the line that starts emulationstation. Adjust X with the number of seconds necessary - you might have to give it a few tests to find the right interval.

isrnick

@mitu Thank you, I'll do that.
