cannot delete files on usb drive

Asked by Jim Harris on 2012-11-19

I am using a usb drive for backup.

I am using Unison to sync files between harddrive and usb.

I inadvertantly backed up the "lost+found" folder.

Now I cannot do a another sync.

Unison does not have permission to read the "lost+found" folder so the sync operation is aborted.

I cannot delete the folder on the usb drive. I've tried reformatting and repartitioning but the folder is still there.

I there a way to get rid of the folder on the usb drive?

Jim

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

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

Can you help with this problem?
