I have a USB and for some reason i can't access it. On fdisk -l i don't see the USB, also not show on gparted or anywhere....

I don't remember the format of the usb.

fdisk /dev/sdc

fdisk: cannot open /dev/sdc: No medium found

Gparted and Disks also fail to find the drive.

Any ideas ?

Updates: Tried with another PC

I tried it in another PC, with Ubuntu Server the same problem.

I get this logs now with

dmesg and syslog

I recreate I think how i failed the USB, but i want to tell if i can rescue it.

I was burn with dd some iso and because it was stack i kill the process and then it can't mount or see with fdisk -l.

Why this happens if you know ? I destroy the firmware ?

Sorry i am stupid :) :P

Cheers

  • What do you mean with "dir to access"? Have you tried fdisk /dev/sdc? The logfile suggests that no partitions were found. Otherwise you would have had a message like sdc: sdc1 before the last log entry. – Freddy Jun 1 at 21:47

  • Do you have a Linux Live CD/USB stick to test if your system is the problem or your USB device? – Freddy Jun 1 at 22:28
  • I test other usb and is ok – pioupiou Jun 1 at 22:32
  • I would try to test with a different system first. You can also try a different USB port. If the problem remains it might be a faulty USB device. – Freddy Jun 1 at 22:42
