Thanks for the hint
It doesn't work unfortunately.
Echoing something into rescan makes it output (in dmesg) basically the 
same message that comes out with blockdev --rereadpt /dev/sdr. The size 
is still detected wrong. Catting "model" also turns out that the old 
brand of disk still being detected. smartctl -a does show the new disk :-)
I tried to write "1" in evt_media_change but it's permission denied :-)

Thank you
