I have a pendrive which is full of viruses. These viruses are .js files. Using linux, I can open the pendrive and see which folders they are in. But when I try to remove them by pressing Del button or via sudo rm filename.extension it gives me an error:

cannot remove 'file.lnk' : Read-only file system

All of the files on the pendrive are like this. I can't even format it with gparted Install gparted but it also gives me an error message.

I have like 3 or 4 folders containing these .js files. I can even open it with gedit Install gedit but can't edit its contents. These folders' names are like:

  • C4
  • d8d8d
  • cfc4c

...and the files are like:

  • gd586d.js
  • id9d9.js

How can I work around this? I would like to remove these files from the pendrive by terminal or any another method.

  • What is the error message you're getting from GParted?

It seems your pendrive device is dead. I am pretty sure, because all times I saw I/O error it meant hardware was damaged.

  • I also think so... I have 2 pendrives with the same problem (vírus). The first one I could remove easily with linux live cd, but this second one... No way! And I'm used to see this model of pendrive with problems and stop working... Look, I could get all the importante files from the pendrive and moved to my HD. Even if I Could do so it still may be damaged? Jun 19, 2014 at 4:09
  • You didn't move all files, but if so, there might be physical sectors damages regardless whether they are occupied or not. The IO error is very serious problem, related to a hardware. Jun 19, 2014 at 4:59
