Serial Ultrabay Enhanced CD-RW/DVD-ROM Combo Drive V (42T2535/42T2563)

This is an optical drive that slides into a Serial Ultrabay Enhanced.


  • Read/Write capabilities:
    • CD-ROM, CD-R, CD-RW (24x read speed)
    • CD-R, CD-RW (24x write speed)
    • DVD-ROM, DVD±R, DVD±R DL, DVD±RW, DVD±RW DL (8x read speed)
  • Tray loading
  • Activity LED

  1. This model requires its original optical drive's faceplate and mounting bracket to be swapped onto the Serial Ultrabay Enhanced CD-RW/DVD-ROM Combo Drive V (universal bezel), otherwise the drive will not fit in properly. It also requires the black plastic stub located at the back of the Combo drive to be removed to fit in as well, due to the lack of an eject mechanism (and the fact that it may prevent the drive's installation).

Problem regarding reading video DVDs

When playing a region-coded video DVD for the first time using a Linux player, you may get errors such as the following:

libdvdread: Invalid IFO for VMGM (VIDEO_TS.IFO)

This is caused by the DVD driver's region never having been set. Use regionset to set some region and retry. It is important that you choose the region code wisely, as you will not be able to read any other regions, and you can only change the region 4 times before it becomes permanent.

With older drives you could use libdvdread to bypass a drives region restrictions, but this doesn't work in some drives, particularly those from Panasonic. Panasonic DVD drives actually refuse to read out-of-region media, and implement RPC-2 fully. This cannot be worked around in any way short of drive firmware changes, which are not available anywhere.
