How is iit possible, that my Pletor Premium and the Plextor 482448 are not able to burn unknown CDRWs. Newest firmware 1.06 on both.
eg: maxell 1-4x (manufacturrer unknown), Platinum 1-4x (manuf. unknown)
The first burning ist ok, then it worsens quickly and burning cycle no. 3 or 4 shows
c1-rates far above 200 (often 500 or more), many c2-errors and uncorrectable errors, even when tested at 4x only.
But now the strange thing: I put these unreadable CDRWs into my prof. audio-recorder (marantz), and quite surprising:
After burning I have error-rates like this:
c1 in average 7-10, c1 at maximum at 35-40, no c2, no CU (and this at testing with 10-24x)
Thus I find it quite surprising, that Plextor is not able to find the correct laser calibration for unknown CDRWs, which every audio recorder does permanently with success.
Then I bought a lot of Sony CDRWs 4-10x (manuf. by Ricoh, a well known manufacturer).
Same situation: Quite fine rates at the first burning (c1 in average below 0,5),
But CDRW is unreadable ofter the 4th or 5th burning!!!
(but these CDRWs I cannot use in the audio recorder, because, 4-10x CDRWs cannot be used). But maybe the CDRWs would recover in an other CD-burner.
The only CDRWs which I use successfully are Verbatim 4x and 4-10x.
Here I have burnt 15 cycles, the error rates are like that:
c1 in average 10, maximum lower than 50, no c2, testing at 10-24x
c1 in average 8, maximum lower than 35, no c2, testing at 8x.
Conclusion: Plextor is a fine tool for grabbing CDs and burning CDRs, but with CDRW you will win no war with plextor.
