    Hello,

    I’ve read many topics of this forum to set up retropie. Most things work but the USB HDD kills me. I tried any suggestions I have found but nothing seems to work.

    I took a 320gb WD Blue from my Thinkpad which I’ve replaced with a SSD and bought a SATA to USB adapter.

    It shows up and I was able to format it. But I can’t access it respectively it seems so and there are no Rom folders created.

    pi@raspberrypi ~ $ lsusb

/dev/sda1            2048   625142447   312570200   83  Linux

    And it does not show up here even it’s said above that it’s listed under /dev/sda1:

    pi@raspberrypi ~ $ blkid
/dev/mmcblk0p1: LABEL="RECOVERY" UUID="6782-8AD5" TYPE="vfat"
/dev/mmcblk0p3: LABEL="SETTINGS" UUID="ae7ba22e-7f25-4575-97bb-b695ef0d2ee4" TYPE="ext4"
/dev/mmcblk0p5: LABEL="boot" UUID="2B9B-8307" TYPE="vfat"
/dev/mmcblk0p6: LABEL="root" UUID="c0fc5f89-e5e9-4aa2-b08b-b0617145c24c" TYPE="ext4"

    It says also the HDD is already mounted:

    pi@raspberrypi ~ $ sudo mount /dev/sda1 /media/usb0
mount: /dev/sda1 already mounted or /media/usb0 busy
mount: according to mtab, /dev/sda1 is already mounted on /media/usb0

    I couldnt mount it to /hdd1 which i created before and mounted it to usb0.

    So, I dont know if there is a problem with the HDD or I’m just doing something wrong while trying to use it. At some point it said that there is a read-only permission.

    How can I now use my HDD so I can place all the Roms there?

    I think an external HDD won’t be able on a raspberry pi.
    The HDD needs to have enough energy to spin the internal drive.

    USB Sticks will work because they don’t need a lot of powe.

    Oh, sorry. I forgot to mention that my HDD is plugged into a powered USB hub. I thought that would be sufficient. Or isn’t it?

    haven’t tried it out yet.
    You can check if you listen to the case. do you hear it spinning?

    and do the lights flash?

    Yes, it spinns and the led of the adapter indiciates that it’s working.

    So… I used the max_usb_current=1 method and it seems to work (and I look forward to move the filesystem to the hdd, thx Spike).

    I got the HDD mounted to /media/hdd1.

    Now it tells me that I have no rights e.g. to create a directory. I did it in command line with sudo, but I wonder how I am able to get my roms there and if I have to create the folders manually. Because the usbromservice doesnt create them.

    Or is it necessary/possible to remove this restriction?
