usb flash drive not working

Asked by dumpa

Hi, I have ubuntu gutsy and a usb flash drive 1Gb s3+ that doesn't work.
Sometimes it isn't detected at all, and sometimes it is automatically mounted but I don't have permission to write or read.

Please help, I have followed lots of forums treads without any success.

I'm a beginner with linux so I don't really know what more to tell you about this problem.

Hi again,
I installed and opened the NTFS-config, there was just one option

"Enable write support from external device" which was uncheked and I cheked it.

Nothing happens still. no usb detected.

Some additional info,

when I look at my computer and connect the usb drive for an instant I'm able to see the flash drive, If I right click on it and try to mount it it says "unable to mount drive, there is probably no media on the drive"

Are your external hard-disk with NTFS partition...?
Are your external hard-disk password protected...?

Unplug and plug your external flash-drive then please open a terminal and type:

sudo lsusb

and

sudo fdisk -l

copy and paste the result here.

Thank you.

Are your external hard-disk with NTFS partition...?

I don't know what this means.

Are your external hard-disk password protected...?

I don't think so.

I'm trying to format my usb drive to see if this helps.

I'm using

sudo gparted

when I do that I see that /dev/sdb (996.22 Mb) is unallocated, it seems to have no partitions (I'm I right)

When I try to create a new partition I get a

"Error while setting new disklabel"

and in the terminal I see

======================
libparted : 1.7.1
======================
Unable to open /dev/sdb - unrecognised disk label.
Unable to open /dev/sdb - unrecognised disk label.
Input/output error during read on /dev/sdb
Input/output error during write on /dev/sdb
Unable to open /dev/sdb - unrecognised disk label.
Segmentation fault (core dumped)

I think you usb device filesystem is in error state and can't be mounted...
Do a check disk on it from Windows, this is the simpler way to correct it.

For this problem to get closer to a solution dumpa will need some help and instructions on how to do a disc check from Windows on a USB device. I don't have that knowledge.

Checking an USB-device on windows can be done this way:
when PC is running, first start Explorer (key-combination <Wndws>-<E> ) and look carefully to the drives on the left side pane.
Now connect the USB-device and wait for a moment.
You will see a new drive on the left side pane in explorer; point to that drive-icon and click with your right-mouse-button.
Now you can choose properties and check the drive there.
Hope this works for you!
