Good day.
Took my USB thumb drive with archived contents; plugged to my printer as done many times and the printer refused to print/recognize .odt files.
Later plugged the same USB thumb drive to the laptop that created them and cannot open any file. Attached screenshot.
How to liberate - unlock the files - explained in baby steps for a very ignorant unskilled beginner, please ?
Note : when the USB drive is plugged-in. those ‘padlocks’ in the image below do not show. After a few minutes, they appear.
Correct. The padlocks on the files list do pop-up about a minute later, and files are locked at all times before of after the padlocks show up as in post #1.
What filesystem type is on the 8.0GB Volume you are having problems with? Is it a Linux filesystem such as ext4, the default with Ubuntu? What OS is on the laptop?
Thanks. The laptop that created all the 8.0GB thumb USB files during at least half a decade has always been plain Ubuntu along several versions. Never had any other OS. Now is 24.04 working fine.
A couple of times has been plugged at a Windows compfuser in the public library to print some files when my printer was inoperative. (If that counts)
If these padlocks show up only “after a while” as you describe above, that might mean the system detected a filesystem error and re-mounted the device in read-only mode … might be interesting to watch the system journal when that happens …
Padlocks did not show this time; tried to open one of the Ḿanuals in that USB thumb drive folder with ‘document viewer’ ; got
Then randomly, tried to open a file “open with”… with the browser; came up with unable to attach here, behaved as trying to save telling me it is already at the “downloads” folder ! . Had to take a screenshot to the screenshot to attempt attaching its image here as did not allow to be selected.
I did not continue to ‘save’ This is too much for my brain. Are the files in “manuals” folder the wrong whatever they cannot be opened by the printer nor ‘document viewer’ and need translation or saved again as something else extension ???
Have you tried to do a filesystem check on the drive partition as suggested above? The link below explains doing that. If you are only using Ubuntu, why have a USB with a windows fielsystem?
