    Exclamation 4 gb usb drive only has 1gb usable in ubuntu

    the title pretty mcuh says it all. its called 4.1 gb drive on the GUI. but it only shows 0.1gb of free space when it should have 3.1 (0.9 is used)

    the screenshot says it all.

    what do you get when you type
    Code:
    df -h /media/disk
    du -h /media/disk
    replace /media/disk with the path where your usb is mounted

    Code:
    sudo rm -r /media/disk/.Trash-1000
    If it doesn't help, fire up gparted and check if there's really a 4gb partition inside your USB.

    This doesn't look like a partition table
    Probably you selected the wrong device.

    Re: 4 gb usb drive only has 1gb usable in ubuntu

    looks like it only has 1 partition on it and its 1gig in size. what does Partition editor show?
    Debian Testing(64bit) + XFCE4 AM2 5200+ ATI Radeon HD4350, 4gig RAM,320Gig and 750gig HDs

    what's the difference between an answer and a solution? An answer is what they want to hear, a solution is what they don't want to hear

    Did you buy that drive off of ebay? I've heard they sell alot of phony drives on there. Do you have a pc running windows to see what it shows there?

    The bold section seems to support the 4gig claim.

    The red sections show problems with the file system.

    If this has no data you need to recover, I would fully erase the drive and re-format it.

    As a test, use gparted to view the drive, and post a screenshot if at all possible.
