Automatic unmounting, USB flash drives and Linux

Hello,


does Linux support automatic unmounting of USB devices (flash drives)
like Windows XP does
without manually unmounting.

Regards.

Windows XP does not !
That also recommends you don't detach removable media without
disconnecting them first !

Windows XP does, you bet. See Windows XP help...

The problem is: does Linux support automatic unmounting?

OK, I watched the video. Your asking should be :
"How to disable write cache to removable devices ?"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The problem is not to pull off an USB device (as it's no more
connected it'd be unmounted (?)), but to be able to pull it off and be
sure stuffs have been written on it directly...
?

OK: "How to disable write cache to removable devices?"

I believe you can do that using "sync" as a mount option. That will however
likely shorten the life of the device.

Use the sync flag when mounting:

sync All I/O to the file system should be done synchronously.
In case of media with limited number of write cycles
(e.g. some flash drives) "sync" may cause life-cycle
shortening.
