[GLLUG] Antec Drive Unmounting

[Chick Tower]

About eight years ago, I installed a 5.25" CD burner in an Antec case 
that has screwless drive rails.  The rails mount on the side of the 
drive and then you slide the drive in until you hear a click, or so the 
manual says.  (I don't recall doing it, but I must have, since I built 
assembled the PC from components.)  Now it's time to change the CMOS 
battery, but the CD burner blocks my access to it.  I unlock the drive 
rail with a slider on the outside of the cage, but I can't budge the 
burner, neither forward nor backward.  Does anyone know if there's a 
trick to releasing the drive rail so I can slide the burner out of the 
way and change my battery?  Thanks in advance.
