Windows – Delete CDFS volume from USB drive in windows

filesystemspartitioningusbwindows 7windows-vista

I recently attempted to install ubuntu onto a removable USB drive. Eventually, I wanted to replace the ubuntu version with another, but the problem is that, besides for the 3.7gb of "free space" I can mount the new boot ISO onto, there is about 6mb of some "CDFS" boot file system, which is preventing any other boot system from being booted from.

So basically, I need to delete this CDFS voluem.

Running diskpart, I do the following commands:

list volume

to which I see volume 1 is the CDFS filesystem I am trying to delete, so then

select volume 1

so far so good

but then:

delete volume

is where the trouble is, because I get the following output:

DiskPart cannot delete volumes on removable media.

I've tried looking this up but couldn't find any conclusive articles, and for sure not on the stackexchange, so:

How do I remove a CDFS filesystem from a removable USB drive, using windows [vista or 7]?

Best Answer

You can try diskpart on windows (as admin)

  1. list disk
  2. select disk n
  3. clean

Now you have a blank USB-Stick that you can format in the explorer
