USB key not working

I have an 8GB usb key that is not shown in Gparted anymore and no automounting happens.
Used it to copy over some files, then dd'ed crunchbang on it. but it seems to not work anymore
I can have it listed (it is sdc)..

me@crunchbang:~$ sudo ls -l /dev/disk/by-id/*usb*[sudo] password for me: 
lrwxrwxrwx 1 root root  9 Sep 29 14:25 /dev/disk/by-id/usb-Generic-_Multi-Card_20071114173400000-0:0 -> ../../sdb
lrwxrwxrwx 1 root root 10 Sep 29 14:25 /dev/disk/by-id/usb-Generic-_Multi-Card_20071114173400000-0:0-part1 -> ../../sdb1
lrwxrwxrwx 1 root root  9 Sep 29 14:49 /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0 -> ../../sdc
me@crunchbang:~$ 

.. but dd'ing on it does not work. terminal says no medium found..
in windows it strangely shows up as a card reader, but I can not format it either.

any ideas how to revive that thing?

Re: USB key not working

What's

lsusb -v

showing? According to the device name (sth. like [0011:2233]) you can also find out if the stick has something like U3 on it, by googling for the device name.

Re: USB key not working

When I get a 'dead' pendrive I use

sudo dd if=/dev/zero of=/dev/<device> bs=512 count=1

to delete any old partition table info, then use fdisk to create a new partition table, create a new partition, & format it.
If that doesn't work, just overwrite the whole disk.

sudo dd if=/dev/zero of=/dev/<device>

To find what device it is, unplug it & then plug back in, run

dmesg | tail

Re: USB key not working

same game... "no device found" for all of fatmacs suggestions.. dmesg shows it, though.

Re: USB key not working

Are you, by any chance putting it into a usb3 socket? Some pendrives don't seem to function properly unless they are actual usb3 compatible.
Failing that, what do you see when you re plug your pendrive & run dmesg | tail?
