The drive cannot read the disc properly if any part of the disc is place outside the tray guiding line. How to Use a Vertically Installed Drive This drive can be installed vertically. You can use only the 4.72 Inch (12cm) discs. (You cannot use the 3.15 Inch (8cm) discs) The drive cannot read the disc properly if any part of the disc is place outside the tray guiding line. How To Use The DVD±R/RW Drive The DVD±R/RW Drive allows writing DVD RW discs using Nero Express and enables "packet writing" (high-speed recording) using InCD. The drive also allows writing DVD R discs using Nero Express. Unauthorized copying of DVD or software titles is illegal and the individuals that make illegal copies will be held responsible for any copyright infringement. Using low-quality discs may lengthen the recording time or not supporting due to reduction in double speed. You can use the DVD±R/RW Drive to playback music CDs, CD-ROM, CD-R/RW, or DVD-ROM discs, like a CD-ROM drive or a DVD-ROM drive. If your computer recognizes the [CD-ROM] icon designated to the DVD±R/RW Drive as the 'E:' drive, insert a CD-ROM or a DVD-ROM disc and access the 'E:' drive. (The actual drive letter of the DVD±R/RW Drive may vary depending on the user's system environment.) To Playback a DVD Video Disc : You need a DVD decoder board or the DVD decoder software program. (Provided with WinDVD Show TIME) Use WinDVD Show TIME to change the region code of the DVD±R/RW Drive. DVD Region Protection Coding (RPC): The RPC feature is supported on DVD players and is used with DVD-video discs (such as movies). Currently, the motionpicture industry has divided the worldinto different regions or zones thatcorrespond to the regional markets intowhich the motion picture industry releasesmovies. Simply put, RPC codes are placedon movies marketed throughout the world,based on the region of the world inwhich they are being sold. These RPCcodes help control and prevent piratingof new movies into other motion pictureregions prior to their true releasedates within those markets. The SH-W162C(TS-H552C) DVD±R/RW drive supports RPCphase II. In the RPC-2 mode, the localcode can be changed by users. RPC-2is selected by default for the SH-W162C(TS-H552C) DVD±R/RW drive. You can change the region code up tofive times via an MPEG application. Please contact your dealer or local SAMSUNG representative if you wish tochange the local code more than fivetimes. MAGIC SPEED What is a MAGIC SPEED? The MAGIC SPEED provides a function that user optionally chooses the disc reading speeds, high speed (Max speed) mode and low noise (X32) mode. The low noise mode offers the best PC environment by minimizing a driving noise. The Magic speed not only functions to decrease a noise by reducing a reading speed but also gets a preventive effect of a disc breakage, which could be occurred by a high speed. Its purpose is to supply the stable PC environment to user. Explanation of MAGIC SPEED Mode and Ways to use Explanation of MAGIC SPEED Mode The Maximum Speed Mode : Set up this mode when you want to read a disc by the maximum speed which is supplied by a drive. The Low Noise Mode : Set up this mode when you want to read a disc by a stable speed, the low speed (X32). The mode selected and set using the Magic Speed feature does not change when you connect the driver to a different PC. Make sure you check the settings before use. Caution: In case of a cracked disc, the disc would be broken if operating in the maximum speed. Therefore, it is recommended to operate in the low noise mode or to immediately make a copy and use it. Ways to Use the MAGIC SPEED The first of all, please install the Magic Speed program from Samsung's homepage. Operate the program by clicking the right mouse button on the MAGIC SPEED Tray Icon. Select a desired mode from a program window, and click "Setup" The reading speed of a drive operates in a selected mode. Close the program window by selecting "Close". At this time, the reading speed will keep operating by the changed speed unless you would change a mode and would end a program. It is recommended to use a "Maximum Speed Mode" when operating a Data Copy & a Disc Copy and to use a "Low Noise Mode" when operating a general operation. Other Function Method to release an automatic operation: This program automatically operates when PC is booting. If you wish to release the automatic operation, release the selected item, Automatic Operation in the Tray Icon menu.

Make sure the region code of the drive matches the disc number. The drive is connected to the sound card but cannot seem to detect it. Your sound card is using AT BUS interface. Connect the card to the E-IDE port or replace the card with a new card with the built-in E-IDE interface capacity. Caution: Possible Errors DVD±R/RW drives record data on the disc by applying laser light onto the surface of the CD DVD, and therefore writing errors may occur if you use a damaged CD DVD , for example . Be sure to eliminate the following error-causing elements before you start writing: * The following settings are recommended for all DVD±R/RW drives: Avoid a situation that requires multitasking , and remove turn off the screen saver. A buffer underrun may occur if the system multitasks while the DVD±R/RW CD-RW drive is writing/erasing. Block any outside attempt to access the host PC during a writing session. An error may occur if another user accesses the printer connected to his/her the system via the network during a writing session. Disable the CD auto - run feature of the CD. Inserting an auto - run-enabled CD in to another drive connected to the same system during a writing/erasing session may cause an error. How to disable the auto-run feature: Windows 98/ME GO to Start Settings Control Panel System Hardware Device Manger CD- ROM Settings . Disable Insert AutoRun. It is recommended that you use the image file format when you write a large number of smallsized files. When there are a large number of small-sized files to write , the system's transmission rate drops and the Superlink feature works at a more frequent rate, resulting in lower writing quality. If you are doing a CD-to-CD write , it is not necessary to check to see if you have available space on your hard disc beforehand. However, in the case of image files, it is recommended that you be sure you have at least twice the amount of space needed for the data on your hard disc , as image files are copied to the hard disc before they are copied to the CD. Use a regulation-length (46cm) or shorter E-IDE cable. Using an E-IDE cable longer than 46cm may cause a transmission error. Do not use more than one type of writing software. Before you install a writing program, be sure to first uninstall existing versions of the program or other writing program ( s ) and reboot the system first . (The Windows operating system may be damaged if you install the Korean version while the English version remains on the system.) Use only the writing software provided by Samsung. You may experience writing errors if you use with other writing programs. Caution: Possible Errors T he disc has bad properties data , and or there are other discs with different properties available under the same ID. 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 Standards 1 Standards 2 Write speed is downgraded for the sake of write stability , if high-speed 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 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.)
