I was looking at the cdfreaks review of this drive
And then I ran into this.
There is more than one way to handle C1 and C2 error detection/correction, but a simple and common way is to detect and correct up to two errors per frame in each stage and detect three or more errors:
* E11: 1 error detected and corrected by C1 layer
* E21: 2 errors detected and corrected by C1 layer
* E31: 3 or more errors detected but not corrected by C1 layer
The sum of these (per second) is called the BLock Error Rate: BLER=E11+E21+E31
* E32: 3 or more errors detected but not corrected by C2 layer
Any E31 is uncorrectable by the C1 layer and will result in the bytes in that frame being redistributed into multiple frames which are passed to the C2 layer.
Any E32 is uncorrectable by the C2 layer and will result in interpolation being used for Audio CDs or will result in third layer error correction being use for Data CDs.
Different drives have different ways of reporting these errors in a Disc Quality scan. Lite-On CD-RW drives will report C1 and C2 errors this way:
Then I Looked at the results. That TY disc is the best scan I've ever seen so the LG is a greatest TY cd-r burner. :eek: Except that the pattern looks odd when you compare it with a very good disc on testers from which I know that they report C1=BLER=E11+E21+E31 correctly.
The pattern is that odd that I actually would think that this Lite On cd-r writer is not reporting C1 as BLER and that comment in the review is incorrect.
Now is there anyone who knows more about this.
Is the LG GBC-H20L - The best cd-r burner out there or is it that the Lite On CD-RW 5239V isn't reporting like the older Lite On cd-r burners ?
Can anyone help me out on this ?
