This is a new occurrence of an old problem. I can not use USB connected drives or memory sticks.

This just started yesterday after a software update. I ran my backup software the same as usual, but it crashed.(Lucky Backup)

In checking, I saw that my EXT4 external drive no longer had me as the owner. I have no idea how the ownership was changed. I had created the single backup directory on this drive about 6 weeks previously.

Since the files on this drive were simple duplicates of the files on my hard drive, I deleted the EXT4 partition and created a NTFS partition on the backup drive.

Once more I did a backup, and once more it crashed.

As a test, I tried to copy 20 GB of photos to a FAT32 memory stick with 32 GB of empty space. This also crashed.

I ran a memory test for an hour and found no errors.

Unsure of relevance, but the log shows continuous errors by LIRC.

Using Ubuntu Gnome 17.10.

Drive Permissions

Basic Drive properties.

1 Answer 1


open up a terminal and try running this command , assuming you have sudo permissions :

sudo chown -R <username> /media/lloyd/<nameofyour drive>

(It asks for your password)

some drives are mounted on /mnt you need to check for that though

And I would not recommend formatting your external hdds to EXT4

  • I am mainly trying to figure out why the permissions changed.

  • Also. while it seems that USB transfers are still working, they have been drastically slowed down. Example: I transferred 7 GB of data to a 32 GB Memory stick last night. It took 1 hour. I transferred the same data from my memory stick to my Windows 7 computer today. (Which I consider to be dead slow) It took less than 10 minutes to transfer using Windows. Something has suddenly become seriously wrong. A memory check did not show any errors in my computer memory.

  • Check out the answer for this post , EXT4 for external hard disks will create problems , since you have re installed your systems your UID/GID s would have changed , hence the read only the link to the post below:: askubuntu.com/questions/579793/…

  • System seems to be fixed. But I doubt that I had anything to do with it. I un-installed a few programs which I suspected. Several programs including "Fakeroot."I was told on Facebook that I needed that, so I reinstalled it, along with "Fakeroot-ng”, and added a couple programs that I thought might help. External drive was re-formatted to NTFS format. Received message that a new release version of 17.10 was due to be released on Jan 10th. I updated Jan 10th. The computer seems to be back to normal today. But I doubt anything that I did fixed things. Suspect update as the fix.

  • This was an internal 2nd drive. Sorry, but the comment about EXT4 external drives was not relevant, although I have tried to use an external EXT4 drive in the past.
