cannot delete files on usb drive

What file system does the USB stick use?
When you last unplugged it, did you use the safe remove feature?

What is the output of:

sudo fdisk -l; mount; lsb_release -a; uname -a

Thanks

What file system does the USB stick use? Ext4 (version 1.0)

When you last unplugged it, did you use the safe remove feature? Not sure, but perhaps no.

What is the output of:

sudo fdisk -l; mount; lsb_release -a; uname -a

Here's the output, but I think this is for my harddrive and not the usb drive.

Try:

sudo chown $USER:$USER /meia/Backup

I assume that is the device you are having issue with

This is all I got:

jim@jim-MS-7142:~$ sudo chown $USER:$USER /meia/Backup
chown: cannot access `/meia/Backup': No such file or directory
jim@jim-MS-7142:~$

Is the USB device in when you ran the command?

Yes.

please note:
the command to copy or type into terminal is:

sudo chown $USER:$USER /media/Backup

and not:

udo chown $USER:$USER /meia/Backup
