It seems you already have an external drive mapped error message

[stefer09]

I run the enable expand to external drive option, and I get the error message that tells me that I already have expanded to a drive, to run the remove expanded storage option from the retropie menu... but I haven't even done that... and can't find that entry in the menu either. Its a fresh install, on an internal ssd, havent expanded storage to usb yet or anything, just tried your script. Any idea what might be causing this? EDIT : this is the error that i'm mentionning :
It seems you already have an external drive mapped. Only one external drive is supported. Please run the "Remove Drive Expansion" script from the Retropie menu before adding a new drive.

Reading the code... I think it's because I have a swap partition on my SSD (running retropie on x86). I think the if with the grep piped grep command is : if there is any other mounted drive or partition other than ext4, it means there's an entry in fstab for a previously used USB mounted at boot?

sudo grep -w UUID= /etc/fstab |grep -v -e ext4 -e swap doesn't help either, I get this :

device; this may be used with UUID= as a more robust way to name devices

Looked into fstab and that line is there...

# /etc/fstab: static file system information.

SO, I edited fstab to remove the extra comment lines :

# /etc/fstab: static file system information.
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation

and I've edited the script so that it checks for -v -e ext4 -e swap

It worked... kinda, there was another error but it flashed by fast and then the system rebooted. My rom directory in the SSD had a localrom folder with all the original folders in a subfolder. But all the games were "gone" in the system menus. Didn't bother putting roms on the usb drive, i ran the disable script, but it didn't move the roms back to their original locations, had to do that manually ..
