A:Answer Since the first two respondents failed to understand the question--their replies being complete non sequiturs--let me try to clarify. If you have not attempted to reformat this flash drive with an ext4 primary partition, I don't want to hear from you. If you have attempted to reformat the flash drive with an ext4 primary partition, please state whether you encountered any problems, and if so what happened. Examples of problems include failure to mount, corruption of data, output from "dmesg | tail" such as "JBD2: no valid journal superblock found" or "EXT4-fs (sdx1): error loading journal," or "sudo badblocks -w -s" reporting read, write, or comparison errors. The reason I ask is that some cheap 64 GB thumb drives tend to malfunction in these ways.
