USB stick not recognised

Hi there,

I have a USB stick here that is no longer properly detected.

Gparted does not list it, neither does fdisk -l.

However, I get a responsive output from dmesg, indicating that the stick is not completely broken:

[18521.104928] usb 8-2: device descriptor read/64, error -110

[18528.602056] scsi7 : usb-storage 8-2:1.0

How can I reformat the stick so that it is recognised by the system again?

Thanks!

Re: USB stick not recognised

Why is the kernel version relevant here? I also tested the stick on a Windows computer and neither it is recognised there.

~ pacman -Q linux && uname -r
linux 3.14.1-1
3.14.1-1-ARCH

Re: USB stick not recognised

Why is the kernel version relevant here?

Because one possible cause for your issue is installing a new kernel but not rebooting, we now know this isn't the case.

You could try zeroing the drive using dd...

dd bs=4M if=/dev/zero of=/dev/sdc

...but looking at your dmesg output it could well be that the drive is dead.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: USB stick not recognised

I guess you are right and the hardware of the stick is broken. I tried dd to overwrite it. But it still does not appear, yet the dmesg changed:
