Lastly, let's see what additional information KProbe software returns for LiteON based drives:
- The package
The retail box includes the internal drive, one audio cable for the internal
connection with the motherboard, mounting screws, quick installation guide
and one CD with PowerDVD 5 Software, Manual and DOS driver.
On the front, on the disc tray there are the DVD-ROM and the compact disc
logos. The phone jack, sound level control and the activity indicator
light are located
on the left side, below the disc tray. On the right side there is the eject
button.
On the rear panel you can see the analogue and digital outputs (SPDIF), the
IDE connection and the power input.
The drive is a half-height internal device, much shorter than the usual CD/DVD
recorder, making installation an easy task for PCs with small
footprint.
Removing the screws and opening the drive's cover voids the drive's warranty. For reference reasons, we post the following pictures. You can click on the mainboard picture for a higher resolution image:
Inside the LiteOn SOHD -167T there are the MT1828E an
optical disk controller chip and the MT1816E for the analog signal process
both from MediaTek Inc. The board as well as the servo control comes from
SONY.
