I did a mistake, probably unplugging my external usb drive during a write operation.
Now, the disk looks like it works fine, except one folder of the disk is shown empty.
phil@GLaDOS:/media/phil/Fumble$ ll
...
drwxrwxrwx 1 phil phil 4096 juil. 21 2018 Image/ #this folder is fine
drwxrwxrwx 1 phil phil 45056 sept. 3 20:13 Video/ #this folder is not readable
...
phil@GLaDOS:/media/phil/Fumble$ ll Video/
ls: reading directory 'Video/': Input/output error

So file are here and seem fine. Now, why can't I access them normally, and what can I do to repair this?
chkdsk /f, or the graphical tool in Windows to repair it. - If you are lucky, it is enough to connect it to a Windows computer and unmount it (remove safely) before you shut down Windows. Otherwise use a dedicated Microsoft tool.) The beginning of this link will shed some light onto the problem (or at least a similar problem), Fast Startup in Windows. – sudodus Oct 08 '23 at 12:49
