I'm using Linux since more than a year, so I don't consider myself as a newbie. Still, I have a persistant problem with all the distros I've used: the USB ...

How do you use USB ?
1. At the transfer of files I can never be sure that the files were sent to my USB stick. I can always see their icons in the /media/usbdisk folder, but it happened to me countless times that I was blamed as I've tried to open these certain documents on other PC ( no matter wich OS ). That was always a blame to Linux!
2. With Ubuntu I have a right-click option "Safely Remove" my USB. It works sometimes, but very often not. I would give 55% stability to USB device handling skills of the distros I met.
3. The transfer of files is very slow ( both USB 1.0 and 2.0). There are no differences neither with CPU. Is it possible to increase the priorities of USB - PC transactions ?
I'm writing this thinking somebody else is satisfied with this group of questions.
The USB handling is a basic need today. I'm using it every day. Thanks for help!

To be honest, it has happened to me too that I've copied files and not actually had them on the USB drive when I needed them, also, regardless of the OS. I think the best way is to see which drive is your USB drive by running the command fdisk -l (as root). Then in the future you can be sure your files will be written if you unmount it manually with umount /dev/sdc1 for example (all depends which device is your USB drive).
As for slow transfer speeds and optimizing them, I don't know and can unfortunately not help you.

I have had these problems in the past, but not in the last 18+ months. Gnome desktop warns you that a device is synchronising if data is still pending. All I need to unmount is to ensure that any applications using it are closed and hit unmount. No problem. Obviously a drive will not unmount without problems if you have it open in a terminal or a media player is reading/checking it.

Asyncronous the guilty
My disciple told me today that the problem with USB lies in asyncronous mounting, and I believe him, cos he's the junior vice-champion of the world in computer science. He brought me to Linux. If I only new how to force USB devices to mount syncronously ? (On that way it would be an instant transfer, like Windows does). Anyway I've tried umount -l /dev/sda1 command and it worked with the few examples, but I don't know wether this works in all cases. And I'm a lazy one too...
