Physical Features:

The drive Lite-On sent us for this review was manufactured in March of 2007 and had firmware BL01.For this review the drive's firmware has been updated to version BL02.

From the front, the LH-20A1L is nearly identical to Lite-On's other "Super AllWrite" drives. It not only shares the same basic bezel design, but has many of the same logos. Along the front of the tray you can see a few showing support for the DVD+ReWritable and DVD Multi specifications, as well as HP's LightScribe technology.

Below the tray you can see the LH-20A1L's single LED. Off by default, this LED lights up green whenever the drive is reading or writing.

If black isn't your color, you're in luck. The retail version of the LH-20A1L also comes with a beige replacement bezel.

The rear of the LH-20A1L is pretty straightforward. By looking at the picture below you can see the drive's SATA interface and power connector.

Technical Specs:

The specs below have been taken from Lite-On's website and the documentation that came along with the drive.

LightScribe:

Note: We took a much closer look at LightScribe technology in our review of the BenQ DW1625. In this review we'll just go over some of the basics and see how the LH-20A1L performs with the bundled software.

The LH-20A1L is one of the latest drives from Lite-On to feature LightScribe technology. Developed by HP, LightScribe lets you burn durable, silk screen quality labels directly onto your CD's and DVD's using the same drive that burned the data. According to HP, it's as simple as burning the data, flipping the disc, and then burning the label.

Of course you can't do this with just any drive, media or software. While LightScribe capable drives use the same laser when burning both the data and label, they have to be able to accurately control the laser's focus and position as well as the spindle speed. They also must be able to recognize LightScribe media. These special discs have a thin dye coating on the label side that absorbs laser light. This triggers a chemical reaction that produces a color change, allowing the user to print text, artwork or graphics.

Even if you have a LightScribe capable drive and media, you will need software that supports it. Most major software companies have pledged support for the technology. However, at the time of this review, the list of compatible software is still relatively short. For the LH-20A1L, Lite-On turned to Nero. Using the bundled software you can both create and burn LightScribe disc labels.

Once you've created your LightScribe label, you're ready to print it. Before you can do this though, you will need to choose the contrast. Keep in mind this option not only changes the level of detail, it also affects the amount of time it takes to print the label. The higher the quality, the longer the process will take.

How long does it take to print a label? For testing purposes, we created a few discs using Verbatim's LightScribe v1.2 DVD+R and color CD-R media. In both cases, the quality has been set to "best". The results are shown below.

Verbatim CD-R v1.2 - 32 minutes		Verbatim DVD+R v1.2 - 28 minutes

The LH-20A1L features what Lite-On calls SmartWrite technology. Previously known as HyperTuning, SmartWrite automatically creates writing strategies for unknown, or unsupported, DVD±R and DVD±R DL media. Simply enable SmartWrite, insert your disc and burn. The new writing strategy is then created on-the-fly.

SmartWrite also works with supported media. When enabled, the drive will ignore the writing strategy stored in the firmware and instead create a new one. This is very useful if you are trying to record a disc that uses another company's MID code (I.E. fake TYG02 code discs).

OverSpeed:

The LH-20A1L also supports Lite-On's OverSpeed function. When enabled, the drive will try to write to your DVD±R media at a speed higher than what would normally be supported. To do this, OverSpeed relies heavily on SmartWrite. When a disc is written at a higher than normal speed, SmartWrite will automatically create a new writing strategy for it.

I should point out that OverSpeed does have some limitations. To prevent people from writing to all DVD±R media at 20x, the writing speed can only be bumped up one level. For example, if your disc was normally supported at only 8x, the LH-20A1L would now give you the option to write to it at 12x.

More Features:

By looking at the picture below, you can see that Lite-On's new DVD writer is identified as a "LITE-ON DVDRW LH-20A1L."

Nero also shows that the LH-20A1L has a maximum CD writing speed of 48x and a 2048KB buffer. This buffer is backed up by SMART-BURN buffer underrun protection as well. According to Nero, the LH-20A1L can also write CD-Text and overburn. When testing the drive's capacity, it had no problems overburning up to 99 minutes with our CompUSA media.

Using Alex Noe's Weak Sector Utility we were able to determine that the LH-20A1L is a "two sheep" burner and is capable of backing titles protected by SafeDisc 2.90. Like most drives, it did not pass the "three sheep" test.

Here is a screen shot from Nero's InfoTool. This program queries the drive to see what its reading and writing capabilities are. InfoTool had no problems detecting the LH-20A1L's maximum reading and writing speeds, recording modes, buffer underrun protection and 2MB buffer.

InfoTool also shows that the LH-20A1L is an RPC-2 DVD drive. This means that the drive's region is stored in the firmware. The region can be changed five times and after that it cannot be changed anymore. While there isn't an RPC-1 firmware available for the drive, there is a utility available that can make the drive region free.

While InfoTool gives us a quick glance at the LH-20A1L's features, DVDINFOpro provides a little more information on some of the drive's reading and writing capabilities. By looking at the screenshot above you can see that while Lite-On's new drive can read and write to DVD+R DL, DVD-R DL and DVD-RAM media, it does not support the Mt. Rainier format.

The LH-20A1L also supports a feature called "bitsetting." Using programs like Nero or CD Speed, you can set the book type forDVD+R, DVD+RW and DVD+R DL media. Take note that the settings are all linked together so when you set the book type for one media type, it is applied to all.
