Well, I always umount before removing any such device, which should

for a fact that MS Windows after 3.x do that. So I wonder just what
use the LED is unless the software which mounts it has some control
over it. True, withdrawing it during a write almost surely will corrupt
it. But so can withdrawing it while there are dirty cache buffers.

This was the point of my bug report.
I had written to a drive that I couldn't see the LED on. When the icon disappeared from the desktop, I thought the drive was safe to remove. Guess what, it wasn't. Ouch corrupted drive. Repeated many times.
Ah, I vaguely remember the discussion here, now.
I don't use the desktop icons for mounting/dismounting, I use
command line. I have never had a problem with umount returning before
the device had been written and all buffers flushed. But then,
this is my first FLASH disc emulation device.
The proposed changes will be more in line with Windows that you will get a pop-up saying that it is safe to remove the drive.
OUCH! NO, NO, NO! Please don't make more pop-ups!
If you want your icon interface to pop up a message saying "WAIT!"
and then go away after the write is complete, that would be preferable
to a pop-up saying it is ok. That forces me to do another click to
dismiss the pop-up. I've got enough problems with unwanted pop-ups
showing up. I get REALLY tired of seeing the window manager tell me that
the Acrobat window hasn't gone away, yet, every time I close the stupid
window. I don't need more!
But I'd rather not have a pop-up at all.
FAR better is not to dismiss the icon or change its state to "unmounted"
view until after the flush takes place. I DON'T NEED NO STINKIN'
POP-UPS!
ESPECIALLY don't make my CLI command create ANY pop-ups ever!

Yeah, I went there and tried to make this request, but I'm not
an "official" bugzilla contributor.
Oh, well, nobody is going to force me to "upgrade" to more pop-ups.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
