    USBs won't mount

    so i have this problem that came up out of the blue. i have no idea what possibly could have caused it.
    i can't mount usb's. they used to automount just fine by themselves, but now they don't mount automatically and i can't mount them manually either.

    this is the command i run when i try to mount usb's manually.

    Code:
    sleepee@sleepee-laptop:/dev$ sudo mount /dev/sdb/ /media/USB/
    i run that command and it just sorta stays stuck there..
    i know it doesn't take more than 5 seconds to mount, so when i pull the usb after i get tired of waiting, i get this

    Code:
    mount: special device /dev/sdb does not exist
    something similar happens when i run fdisk -l
    Code:
    sleepee@sleepee-laptop:~$ sudo fdisk -l

    if i run that command with the USB in, i get that output, but the terminal won't give me a prompt until i remove the USB.
    running the command without the USB will give me the same output and will immediately give me prompt too..

    gparted won't recognize the USB partition either...

    i'm kind of a newbie so i don't know what else to try. i just can't manage for my laptop to see my usb's.

    *Correction*
    My Linux install won't recognize my USB's. My windows partition sees my USB just fine.
    BTW, i'm running 64 bit Mint 12 (based on Oneiric) if that matters

    Please help!
    TIA

    I have this too. for me it was a hardware error, by plugging the usb drive into a diffrent port on my pc it automounted. give that a try, it might work

    Re: USBs won't mount

    yea, that's what i thought at first too. my laptop has 4 usb ports and i tried them all, but with no luck.
    but i don't think it's hardware anyway, because any time i boot up windows on the same computer (which is very, very rarely lol) it'll work just fine.
    also, i've plugged in my android tablet and it'll get recognized.... ususally... sometimes plugging in the tablet gives me problems too..
    i don't know what it is, but i'm probably going to do a re-install when the new linux mint comes out anyway... but i kinda wanted to figure it out before i reinstall just to see what exactly happened.

    Re: USBs won't mount

    Try using disk utility? And maybe the drive is formatted to a filesystem not linux compatable? Just my two cents.

    Question Re: USBs won't mount

    The same is happening to me on my dad's Linux Mint laptop. I have filed a bug report nothing yet. I have asked this question many times in the Linux Mint forums, but no helpful answers yet.

    I don't think so. I've formatted it to fat32... multiple times... with multiple usb drives.

    I don't know. this is really weird. I'm thinking it has to be Mint-related because, besides Windows and Puppy Linux on the same computer being able to read the USB, I just bought an Asus Eee PC netbook and put Mint 12 on it and the exact same thing happens!
    I think I might try and see if I can mount it using Ubuntu... or maybe try the Mint 13 RC and see if they've fixed it.

    Have you tried reading the USB on that computer with a different OS? like Windows or some other Linux distro?
    Because right now, I've got 3 machines with Mint and all 3 have this same problem.
    Maybe they'll fix it with Mint 13? It is an LTS release after all...

    Check and see if you have pmount installed. If not, install it.
    It will auto-mount usb devices not listed in /etc/fstab
    You can find pmount in Synaptic, or in terminal:
    Code:
    sudo apt-get install pmount
