nDVD Super Multi Double Layer drive cannot use discs that allow writing faster than 16x speed (DVD-R and DVD+R media), 8x speed (DVD-R (Dual Layer), DVD+RW and DVD+R (Double Layer) media), 6x speed (DVD-RW media), 5x speed (DVD-RAM media).

nSome types and formats of DVD-R (Dual Layer) and DVD+R (Double Layer) discs may be unreadable.

n2.6 GB and 5.2 GB DVD-RAM media cannot be read from or written to.

nDISC created in DVD-R (Dual Layer) format4 (Layer Jump Recording) cannot be read.

nIf the disc is poor in quality, or is dirty or damaged, writing or rewriting errors may be noted - ensure that you check all discs for dirt or damage before you use them.

nThe actual number of rewrites to CD-RW, DVD-RW, DVD+RW or DVD-RAM media will be affected by the quality of the disc itself and the way in which it is used.

nThere are two types of DVD-R media available, authoring discs and general use discs. Do not attempt to use authoring discs as only general use discs can be written to by a computer drive.

nYou can use both DVD-RAM discs that can be removed from a cartridge and

DVD-RAM discs designed without a cartridge.

nYou may find that other computer DVD-ROM drives or other DVD players may not be able to read DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R (Double Layer) or DVD+RW discs.

nData written to a CD-R, DVD-R, DVD-R (Dual Layer), DVD+R or DVD+R (Double Layer) discs cannot be deleted either in whole or in part.

nData deleted/erased from a CD-RW, DVD-RW, DVD+RW or DVD-RAM disc cannot be recovered. You must check the content of the disc carefully before you delete it, taking care that, if multiple drives that can write data to discs are connected, you do not delete data from the wrong one.

nIn writing to DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R (Double Layer), DVD+RW or DVD-RAM media, some space is required for file management, so you may not be able to write to the full capacity of the disc.

nSince the disc is based on the DVD standard, it might be filled with dummy data if the written data is less than about 1 GB. Therefore, in these circumstance, even if you write only a small amount of data, it might take additional time to fill in the dummy data.

nWhen multiple drives that can write data to discs are connected, be sure that you do not write to or delete data from the wrong drive.
