From: coltrane on 9 Jun 2010 17:51 I have been loading CD into ITunes and at first all the disc were being read at approximately 40x. Then "something" happened and now all the discs are reading at approx. 17x. What might be the reason for this? thanks john

Actually the speed is now down to 7x. The read starts at 7x and stays there. The situation is that when I was first importing discs the reads were at ~40x for the entire import. Now the discs import at 7x. I have 400 more discs to go and I'll never get it done at this speed. I don't have the patience. thanks again john

If so then the source disks are causing the problem. If the speed is still slow with the prior 40x disk try using some canned air to clean the drive, while no disk is in it but with the drive bay open. Possibly a little dust buildup on the lens is making the drive need to go slower. Any chance you were saving the data to a drive that was not on the same cable (usually faster) as the CD but now you are saving to a drive attached to the same IDE cable.

Infotool gives information on the modes supported by the burner. The "Disc" tab shows data for the disc inserted in the tray. http://majorgeeks.com/screenshots/n/neroinftool.gif The author of Infotool is Eric Deppe, and the tool is bundled with Nero, in the tools folder. The tool is also offered separately for download. The version I use, came with Nero. http://majorgeeks.com/Nero_InfoTool_d120.html The other tool is "Disc Speed". It can do quality tests on CDs. The quality test could either tell you the CD was bad. But if many different brands of CDs are bad, then you'd suspect the drive was the problem. http://majorgeeks.com/Nero_DiscSpeed_d118.html An optical drive is also subject to bus limitations. To give an amusing example, I was attempting to burn my first DVD9 dual layer on my burner. The LED on the drive would flash on and off slowly, indicating something wasn't right. But I didn't have my thinking cap on at the time. I thought maybe the media was bad. My DVD burner is in a USB2 enclosure, which is plenty for the job (up to 30MB/sec). Later, I happened to look in Device Manager, and noticed my "Enhanced" USB2 entry was missing. Doh! The reason the light was flashing like that on the drive, is I was running USB 1.1 mode, 1.0MB/sec data rate, which would have taken hours to finish my burn. After I fixed the stupid driver issue, it worked properly. The same thing can happen with the IDE bus. For example, it can drop into PIO mode and run pretty slow. If any "speed" type benchmarks are a "flat line", perhaps it is a bus or cable issue. Like what mode is being used for the bus or cable. HTH, Paul

At first the drive door wouldn't stay closed. Then it wouldn't read the disc at all. Now it will read a disc but the speed is down to 2x. I tried to use an optical disc cleaner that I use for my stereo cd player and I also reinstalled the driver and the read speed is still down to 2x. I hate to do it but at this point I might as well try buying a new drive because I think the canned air did some permanent damage. At least the drives are only $25. oh well..
