    Do you get any output when you use the mount command? If so, what? Is this an external hard drive? flash drive?

    the usb is a flash drive, and the only output is a blinking underscore.

    i've tried to mount other flash drives the same way and get the same result

    After you plug the device in, try the dmesg command....it might give a clue.

    Code:
    tail -50 /var/log/dmesg
    Should give you the last 50 lines. You may need to use sudo or root as warranted.

    thanks for the replies

    i tried the above code and the response was

    Code:
    tail: cannot open '/var/log/dmesg' for reading: No such file or directory
    but running dmesg does give me some info about the connected flash drive

    You can post that if you want. Someone might be able to make sense of it.

    In your first post you indicate your Fedora instlalation crashed and you were logging into Rescue Mode. You are trying to then mount the flash drive, correct. What is on the flash drive? Data? Do you have another OS on it? What filesystem type?

    my flash drive is file format ext4 and i have data that is owned by root of my crashed installation

    i'm trying now to somehow gain root access and chmod all the data so it is accessible to all and then just install a new system

    i successfully was able to view data on another flash drive but can't on the one that i'd like the data from
