The write speed for a disc can be restricted if:
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.
1.
Samsung standards to decrease writing speed
2.
Standard 1:
If there are high-speed discs in the market that have very bad property
data, the writing speed is decreased. This also happens if there are low-speed discs
with the same ID.
Standard 2:
Discs for which the speed was reduced, will be examined again. If low-
speed discs are no longer available in the market under the same ID as a high-
speed disc, the decreased writing speed will no longer apply to the high-speed disc.
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.

Note
We update the list of supported media on a regular basis and make them available
in our firmware upgrades.
