After trying to simulate a record with Feurio, I got this enlightning message:
WARNING: Can’t set recording speed: 40x!
You have selected a recording speed of “40x”.
The writer doesn’t accept this speed and reports “16x” as a recording speed.
Background: Feurio! first sends the desired recording speed (so in this case: 40x) to the recorder. After that Feurio! “asks” the writer, which is the current recording speed - and here the recorder reported: 16x - therefore this message.
a) Writer doesn’t support this speed:
A CD-writer not always supports all speed “steps”, e.g. an 8x writer needn’t support 6x, 4x, 2x and 1x - many 8x recorder e.g. only support 8x, 4x and 2x. When trying to select another speed, the writer “rounds” the speed value, in this case to 16x.
b) Writer decreases the speed due to the inserted medium:
Some writer also “check” the inserted medium and eventually deacrease the writing speed.
Special remark for writers of the “Philips CDD series” (all writers with identification string “Philips CDD 4xxx” or “IDE CD-RW xxx”, and also some “OEM-models”, like IOMEGA Zip-CD, certain HP-models and so on):
These writers have an internal table with all tested media. Only these blanks will be burned with the maximum speed - all media unknown to the writer will be burned with a lesser speed.
“OK” -> Start the recording with the speed the writer selected (16x)
“Cancel” -> Cancel the recording
Well, that explains a lot of things. It seems that the writer will only burn at maximum speed on tested media only, and since this media is quite new, it isn’t in its database (firmware). So this should get corrected with a firmware update, although non is yet avaliable at the MSI site.
