I burned a live USB of Ubuntu on a flash drive nad I used it to install to a different flash drive which does not work fine.

Specifically, the one it's installed on is 16GB and the boot goes a little like this: I boot the computer, I get to the log in screen, I log in, and after that it goes black displaying the following errors:

Basically, I get multiple lines saying:

EXT4-fs error (device sda1): ext4_find_entry:[number]

What's going on? How do I fix this? I use an Asus CM5571.

First of all, a premise: doing a full system install on a flash drive is generally not recommended, because it will definitely shorten its life. USB thumb drives are not suited for continuous, repeated writes on it and a full OS writes a lot of files while running.

It would be much better to use a live system with a persistence file. Now, about your problem:

EXT4-fs error (device sda1): ext4_find_entry:[number]

Your have input/output errors on the drive. This can have two causes:

  • the file system is damaged
  • the drive is damaged

In the first case, you can easily solve it by running a file system check. You can use the live USB you have (the one that works fine), run it and open Gparted after plugging the faulty drive. Then:

  • select the faulty drive from the dropdown menu
  • click on the main partition
  • click on Partition → Check
  • follow the instructions

However, if the drive is faulty there is little you can do. You should think about getting a new one before it's too late because you risk losing data.

Bottom line... building bootable... reliable... USB flash drives is voodoo art. Sometimes it works. Sometimes it doesn't.

You could format the target 16GB USB flash drive and try to install again. It may work, or it may fail in any fashion it chooses.

It's much more reliable to burn the .iso to a DVD.
