[Bug 82094] USB safe unmount from desktop data corruption

[Piero Ottuzzi]

Public bug reported:

Binary package hint: kubuntu-desktop

Hi there,

yesterday I plugged a 512MB MP3 pendrive in my kubuntu edgy powered laptop and started to copy there about 300MB of MP3s: just few seconds and for the KDE interface everything was copied there!!!
But we all know this is a trick of the filesystem management under linux: it is saying that everything was done but it deserves to do the real work when it thinks it is a better time.
So I went in the desktop and right-clicked on the MP3 player icon and I choose "Safe unmount" (or whatever it is..): almost immediately the device was unmounted and... guess what... not all 300MB where really copied!
I plugged the device again, copied files again from KDE (no more than 5 secs and the operatione was done) and I opened a new konsole:
> sudo umount /dev/sdb

This, obviously, fixed the problem: after 4-5 minutes the prompt came
back and all the data was written there.

I think this is really a nasty bug!!!

Bye
Piero
