Now, please note that this is a sub-question of my old Changing Ownership: “Operation not permitted” - even as root! question. If you do not want to visit that link or cannot, to sum up, while attempting to use:

sudo chown (...)

To change the ownership of a file inside of a USB drive, it was unsuccessful, as the file had the immutable flag set in its extended attributes. This was the solution that worked, removing the flag via:

sudo chattr -i (Path_To_File)

As this was fixed, I basically put this in the back of my mind where I would remember it in case of repetition of the error. Recently, I was formatting a USB custom, and ran into the same error, except this time, nothing that was suggested to fix said error the previous time, has worked. Here's your command output that I know you all love:

sudo chown david:david ~/USB5/Format/type.cr

Please note that I have checked this command, and neither the (~) general path, nor the specific path work. The following is my output:

Operation Not Permitted

Of course, I have tried the fix from before, and the file does not have the flag. What can I do to fix this?

Suggested answer below:

sudo mkdir /media/flash
sudo mount /dev/sdb1 /media/flash -o dmask=000,fmask=111

This just hangs on the second command, I left the computer for over 2 hours, just hanging.

EDIT: Changing to EXT4 Did nothing, same error.

  • which filesystem are you using on your USB drive? – syss Mar 7 '16 at 13:42
  • @syss For now, FAT32, however eventually I will format to NTFS for specific use – David Mar 7 '16 at 18:43

    Then you might want to take a look at this questions: askubuntu.com/questions/118199/… askubuntu.com/questions/11840/… Basically you need to remount your partition with the correct rights. – syss Mar 7 '16 at 19:00
  • Fat and NTFS are not native Linux file system types, therefore do not support Linux file attributes. Use a native Linux file system like Ext2/3/4 or F2FS. – acejavelin May 4 '16 at 15:10

I'm using Sparky linux (Debian testing), but I had the same problem and this may work for you.

After trying all the command line suggestions and not having any success, what worked for me was simply using Gparted and formatting the drive to ext4 and then doing a reformat to fat32 again and all is well.

It was kind of strange as I had been using this 16gb Adata USB3 for a couple of years and never had any issues. Hope it works for you.
