This has been met for all discs. It is not a coincidence that many well known manufacturers chose this burner to use as their OEM device. There were other drives, including some combo drives and readers which had scanning ability. If you compare this with other drives, one of several results can occur. On a simulated overburn, the BenQ DW was able to register a maximum capacity of 99 minutes 56 seconds and 41 frames. The 7 64bit install no service pack should be 3.

Might this be a firmware bug related to the way the drives support dual-layer discs? We received a black coloured drive, but there is an option to choose between this or a white coloured burner. You can easily change the default parameters of your burners with this powerful utility. However, this ability began cropping up on drives as part of less-well-documented firmware features that exist with drives of specific chipsets.

This greatly helps to reduce data access time and also to deliver superior reading and writing quality. The data area of the disc has been burned, and the disc is thus a coaster. As the writing speed is increased, signal loss becomes the key cause for the significant decrease in writing quality. On a simulated overburn, the BenQ DW was able to register a maximum capacity of 99 minutes 56 seconds and 41 frames. Click for more about me! The disc quality is not too bad according to the DW — a bit poor on the inside ring, but otherwise quite decent.

The test kit that arrived at our labs included only the burner.

Worse still, the drive da1640 ignores our request for 4x write speed. The drive does not support Mount Rainier and it uses the well known RPC II region control, allowing a user to change the drive’s region at most 5 times. I decided to write a 99 minute 00 second 00 frame disc, as in my experience, getting too close to the simulated value will cause issues.

It was an unexpected result, as contemporary drives in that era would often have problems maintaining high read speeds as they struggled to cope with the marginal ddd that was just out of spec.

Looking at the above list, the appropriate line is this one: I suppose this write-up is my way of thanking the drive for years of trouble-free service. You must log in or sign up to reply here.

However, simulating such a burn on the BenQ DW resulted in a true dw1604 no burn to disc and a value which suggested overburning was indeed possible.

Such long simulated capacities are nice, but can it actually be achieved? Removing the screws and opening the drive’s cover voids the drive’s warranty. The sample that we received came with firmware version BSHB.

I currently have a 32 bit. To that end, normally such information can only be garnered through the use of expensive disc analyzers such as CATS.

Do you already have an account? In the below set of four images, I scanned four different types of blank CD-R one of the Plasmon discs is a mis-identified Ritek recorded by a slimline DVD recorder at 24x.

The quality scan features reported PIFs as sum8-values rather than sum1, thus could not be directly compared with the LiteOn or ECMA standard guidelines, although different drives did always vary with their opinions of the quality of discs.

I would like to update to a 64 bit. Sense key not important: There were other drives, including some combo drives and readers which had scanning ability. If you compare this with other drives, one of several results can occur. With an integrated heat chimney design, ADCS redirects the heat flow out of the drive and still provides for protection from dust. The added firmware modification support is a big bonus as well.

More importantly, what size is the ISO?
