Caution: Possible Errors - Lenovo Ultra Slim DB66 User Manual

■ Caution: Possible errors

The drive uses laser light to write data onto the surface of the disc. Writing errors can occur if you
use a damaged disc. Make sure to prevent the conditions below before you start to write a disc.
Note
These settings are recommended for all drives.
1. Do not use multitasking. Disable the screen saver.
▶A buffer under-run can occur if the system uses multitasking while the drive writes data.
2. Do not let any outside computer access the host PC while the drive writes data.
▶An error can occur if another user accesses a network printer while the drive writes data.
3. Disable the CD auto-run feature of all drives.
▶If you insert an auto-run CD into another drive within the same system while the drive writes
data, this can cause an error.
4. It is recommended that you use the image file format when you write a large number of small-sized
files.
▶When there are many small files to write, the transfer rate decreases and the Buffer under run
protection feature works at a more frequent rate. This causes a lower writing quality.
▶If you are doing a CD-to-CD copy, it is not necessary to verify if you have available space on
your hard disc.
However, in the case of image files, we recommend that you make sure you to have at least two
times the amount of space needed for the data on your hard disc. This is because image files
are copied to the hard disc before they are copied to the media.
5. Do not use more than one type of writing software.
▶Before you install a writing program, make sure to first uninstall existing versions of the program
or other writing programs. After you uninstall any software, restart the PC.
(The Windows operating system can be damaged if you install different language versions)
Note
We recommend that you use the data recording software provided by Lenovo.
If you use other recording software, this can cause an error.
The write speed for a disc can be restricted if:
1. The disc has bad properties, or there are other discs with bad properties under the same ID.
The drive examines the disc properties to determine the best write conditions for the type of disc.
Because the two types of disc have the same property data but different properties, it is often not
possible to use the same settings. It is necessary to decrease the writing speed to make the writing
more stable.
If discs from two different disc makers have the same writing speed according to the labels, but
actually have different writing speeds, it is necessary to reduce the writing speed.
Note
It is possible that you do not get good writing quality with discs from manufacturers that are
not registered in the drive's firmware.
We thus recommend that you only use discs from recommended companies. Always make
sure that the writing was successful before you put the disc in storage. This is very important
when you want to store important data.
(Lenovo is not responsible for any loss caused by a backup failure)
Note
We update the list of supported media on a regular basis and make them available in our
firmware upgrades.
