On my Dell Inspiron 700m I have the NEC 6500A DVDRW Drive.  You can pull it out unlike most computers.   A few questions I have.....

1.  If it uses standard Windows Drivers how does it know the Brand, Specs of it? From the Firmware?

2.  Is it connected to the Pc differently since you can pull it out?  Reason I ask is it shows up as EJECTABLE MEDIA, Like a Thumbdrive, external hard drive, etc but other Pc's with Drives do not show up as ejectable
