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
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.
Standards 2
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.)
