I also can confirm this bug.
I have an HP Pavilion dv6106eu with a TSSTcorpCD/DVDW TS-L632D.
Killing hald-addon-storage: polling /dev/hda brings the system back to normal working speed.
This is really annoying.
From what I've seen on the internet, these drives do incorrectly report "Incompatible medium installed" instead of "No medium installed".
But in any cases, please find a fix. Windows can deal just fine with the drive.
Also, doing a hdparm -w /dev/hda seems to work for some people...
