The drive's write strategy is set in a way that the drive examines to examine the disc properties and determine s the optimal write conditions for those properties. For example, many disc makers do not bother to insert property information distinguishing 48X disc s from 32X disc s . Since the two types of discs have the same properties data , although they actually have different properties, it is often impossible to respond to the situation with a single write strategy. In order to ensure stable writing , it is necessary to downgrade the write speed. If discs from two different disc makers have the same write speed according to the labels , but actually have different write speed s , I i t is necessary to downgrade the write speed to ensure stable writing. Samsung' s Standards for Write Speed Restriction Write speed is downgraded for the sake of write stability , if high-speed Standards 1 discs available in the market have particularly bad properties data , or there are low-speed discs available under the same ID. Speed-restricted discs go through further examination and adjustments later. If high-speed discs are available under the same ID with as low-speed discs (speed restricted at present), the speed restriction is removed when Standards 2 the low-speed counterparts become no longer a una vailable in the market under the same ID. You may experience lower write quality in case if you use disc products by some disc makers which that are not registered with the product's firmware. Therefore, it is recommended that you use only discs by recommended companies . Even , and even if the write session is completed successfully, check the write quality before you put the disc in storage , especially in case of an important data backup. (Samsung is not responsible for any loss resulting from data backup failure.)

Cannot playback or record on both sides of a two-sided disc simultaneously. The read/write capacity of the supported discs depends on the condition of the disc and the recording format of the drive. Therefore, the read/write quality may not be perfect. Severe vibration or external impact may decrease the quality of printed images. Please firmly place the product onto the PC before use. In case of disk identification error message, thoroughly clean the surface of the disk where the label is presented and then start printing. The quality of the printed image cannot be ensured if printing an image on the area which is already used for printing. For more information on the writing and duplicating the Lightscribe disk label, install Nero software and refer to the HELP section.
