In the following table, we have gathered the findings of the DVD quality measurement tests. On the left side of the table, you can find the discs that did not produce uncorrectable digital errors (POF), while on the right side are the rest of the discs. For detailed measurement data, visit the corresponding pages.

- Bit Setting

- Overburning

The drive is not able to overburn DVD media, according to CD Speed.

- SmartErase

SmartErase is a technology which can destroy recordable discs and data on recordable discs permanently. SmartErase will overwrite the data stored on recordable media with random characters and make the disc and data stored no longer can be accessed or restored.

To erase the data on your CDs and DVDs and destroy the disc with SmarErase, you need the
following aSmartErase-capable drive like the LiteOn iHAS324, the SmartErase software (available through Nero Essentials 8 suite) and of course, a recordable CD or DVD.

SmartErase will destroy the disc and the data on the disc. Once the data is destroyed, it can not be restored. SmartErase supports all recordable media, but cannot erase or destroy rewritable media.

SmartErase provides two methods to destroy the disc and data: Quick Erase and Full Erase.
Quick Erase only destroys the information stored in Lead-In area and data stored on the first
track of a disc. It takes less time to erase a disc but not all the data on the disc is destroyed.
Full Erase destroys all the information and data stored on a disc. It takes a longer time but all
the data on the disc is destroyed.

If you use Full Erase mode to SmartErase the disc, all the information and data stored on a disc is destroyed and the disc can no longer be restored again. If you erase a disc with Quick Erase mode, not all the information and data is destroyed. The information and data which is not destroyed may have the chance to be restored by specific devices and software.

How to use SmartErase

1 Launch SmartErase from the menu of the burning software bundled with your drive. In our case, we used Nero Express Essentials 8 which intagrates the SmartErase application.

2 We select our LiteOn drive in the drop down menu.

3. The next step is to insert a DVD recordable disc. We used a DVD-R full with data.

4. You are ready to 'SmartErase' the disc. Click Quick Erase or Full Erase to erase the disc.

The 'quick erase' function for a DVD R SL will not take more than 30 seconds. The disc was not readable or even recognizable by any DVD burner we tried after a quick 'Smart Erase'.

The 'Full erase ' takes more than 7 minutes to complete. Again, the 'SamrtErased' disc is completely unreadable.
