| 188745 | 2003-11-02 17:40:00 | have you tried reinstalling nero? Some times programs stuff up and need to be reinstalled but they don't tell u. (seeem s like windows.............) |

| 188746 | 2003-11-02 18:47:00 | James did say that he's never had problems with burning at 48x though. | somebody (208) | ||
| 188747 | 2003-11-02 20:48:00 | ... except his cds exploding ;) Yes I agree with RevSpecies and Chill, burning at 48x just isn't accurate enough for audio cds, theres a much higher error rate. |

| 188748 | 2003-11-03 01:51:00 | I would try reinstalling the software. There are so many things involved in writing CDs that installing almost certainly involves a lot of checking the actual drive the software has to work with. I have to say that if a CD written on the drive can be read on the same drive, but can't be read on an audio player that means that the writer is OK. :D It's an "unfortunate" fact that audio players are designed for pressed CDs . Pressed CDs have a much greater difference between pit and no-pit than the dye-based layers on CD-R and CD-RW disks. The faster the recording is done, the less energy goes to record each bit. Recording slower might help. A different brand of disk might help. But I don't think that DSE are to blame. A new drive "identical" to the one which exploded might have the same problem. :D |

| 188749 | 2003-11-03 02:06:00 | Well, ONCE AGAIN!!! Dick Smith's are ... beyond words and have said they will give me $99.00 for the drive as "it is not meeting your expectations". I have to say, these guys are bloody good. I do need to say though, that these Cyber Drives are not of ... "high" quality. I was extremly happy with my Aopen drive and this was a huge let down. Well, thanks for your ideas and help people (I will remember the 16x burning next time). Thumbs up to DSE James |

| 188750 | 2003-11-03 04:15:00 | Yes, DSE are pretty good, but dont get carried away with your "need for speed". The microseconds you save burning at x48 dont really compensate for the possibility of exploding CDs destroying yet another new drive. If I knew the elastic moduli and UTS of CD disks I could calculate the bursting speed of CDs and see what sort of safety margin is built in, probably not much. It wouldnt require much of a homogeinity defect in the disk, a stress raiser, or a bit of out of balance to lead to catastrophe. Used to do these calcs for turbine disks, grinding wheels, and other high speed components once upon a time. |

| 188751 | 2003-11-03 04:25:00 | The material is polycarbonate, Terry ... I'm sure the properties will be available online. The peripheral speed is a bit frightening at 52x. I think the x1 speed is 300 rpm or thereabouts (so perhaps they should be "reinforced" with titanium dioxide, like the plastic spouting.) :D) | Graham L (2) | ||
| 188752 | 2003-11-03 04:49:00 | Thanks Graham, I found the required data, albeit in psi and density in lb/in cubed etc, good job Im bilingual units-wise. Unfilled polycarbonate is also said to not have good fatigue strength and also has poor notch strength, ie it shouldnt be played more than once :) |

| 188754 | 2003-11-03 04:57:00 | They probably rely on the strength of the screen-printed label on one side. :D And Philips will have done the numbers for the audio CDs. That's what the standard is written for. I bet no-one has thought of recalculating the actual stress at the higher speeds. :D I haven't looked, but I have an idea that CD-R and CD-RW won't have the Compact Disc logo, because they are not in comformance wuth the standard --- not least the bit/no-bit reflectances. Philips have said that any music distributers which use copy-protection are breaking the licence ... you can use the logo if the CD is according to the standard. |
