SOLVED: It doesn't happen anymore with the new update.
It's probably because of xfce. It happened on thunar first, I was changing the name of some file. Then, all file names in that folder was like "s thi thi .avi" and before it was like "somethingsomething.avi" Exactly like this. And second time today, on xfce panel, same thing happened on time text like "25 uary 21" it seems weird.
create new user account (just cler setting, don't set anything), and try if under new account it works. Maybe some wrong in your setting
Hi,
Make an fsck of the drive, so to check the drive for possible errors, if the above fails
It says file system mounted don't try it like this etc. Hmm so I should do this on usb flash, when it's unmounted I guess? Am I right?
@alium it only happened once or two. OK now.
Yeah, do that with Live ISO.
