How to find out in Linux that data has been written to a USB flash drive (there is no indicator on it)?

Question

linux

From the advent of USB support in Linux until today, there has been a bug in Linux (or a banal flaw, perhaps this is a flaw not at all in the kernel itself - but in the GUI). That is, when copying files to a USB flash drive, the indicator there is random, for beauty - it does not display useful information.I copy files to a flash drive, the progress bar reaches 100%, but the flash drive flashes for a few more minutes (either data is being written to the flash drive, or synchronization is in progress, or something else). I bought today without thinking a 32 GB flash drive (USB 2.0) the size of a fingernail, on which there is no indicator. And here's the problem - if you upload files to a USB flash drive, wait until the progress bar reaches 100% and disappear, then distort it, of course it will be damaged. You have to re-format it. Of course, I don't like it very much. Interestingly, in Windows, starting with XP, there have never been such problems. There, the progress bar really displays the process of copying files.

The question is whether it is possible to use such a flash drive in Linux (I just don’t see the point in copying the data to the flash drive, and then half an hour, or just in case, wait for an hour until the data is written). Maybe there is some kind of program (USB monitor, etc) that shows in real time what is happening with the flash drive, or it is better not to use such a flash drive in Linux, but only in Windows.

PS: Problematic distributions - Ubuntu, openSUSE, ASPLinux (been dead for many years), Debian. Problematic desktop environments - Cinnamon, KDE, Gnome, XFCE - this is where the progress bar is random. For 15 years, I have not seen a progress bar in more than one distribution that would show the actual copying of files.

Answer 1

Let me guess the main cause of the problem: the flash drive is formatted in NTFS.
