This is not my case, so I had to add the following step. In some other tutorials I have read, it considers there are partitions below “sdX” (like sdX1). When it finished, if I run a lsblk, I only see device “sdX” without any other partition. For me, it took more than an hour for a 16 GB USB from a laptop from 2010. Remember substitute the path by the one that corresponds to you. Use another command to delete all content on device. In this post, I write “sdX” and “sdX0″ whenever I make reference to device and partition, respectively.Īn alternative to lsblk command would be: In my case, device was “sdb” and partition “sdb1″. Identify path of mounted unitīefore plugging the USB flash drive, check the devices in your system by using this command in terminal:įirst level of hierarchy represents devices, and second level represents the partitions inside that device.

In any case, we would like to fix our USB to avoid loosing a valuable storage device.

Sometimes USB memory sticks just become unreadable, probably because we have remove it from the port before unmount it or because we had to force to stop a process that was operating with it.
