i copyied one of my music CD's onto a CD-R. then when i went to play it, it started off fine then would skip repeatedly or stop for 20 secs at a time? any suggestions would be appreciated thanks

What speed are you burning at? I've heard that for reliable results you have to burn at 1x and don't do anything else on the machine, just let it copy.

i first burned successfully at 2x if i burn at 1x will that fix the prob?

I gave you some excellent links to look over...if you would go there and do some research you will find the answers to your questions and make your burning experience alot

You might also check on how your manufactures recommend you clean both the burner and the other CD-ROM - might just be dirty optics.

some cd-rs are better than others, i suggest you use blue dyed blanks, other cd-rs can be very unreliable

I'd have to agree with Wiz. The brand of CD-R makes a huge difference. For audio I've had the best luck with silver (Memorex) or light blue disks. I've always burned my audio CDs at 2x without any problems. Good luck.

Software applications use buffering as a process for accessing information from the hard drive. The IDE interface uses a type of buffering called FIFO. FIFO stands for First In First Out. This is a type of buffering where the first information into the buffer is the first information flushed from the buffer. There are two types of FIFO, single FIFO and dual FIFO. The circuitry on the motherboard determines whether a given system uses single or dual FIFO.
Single FIFO
With single FIFO, both IDE cables (channels) share one buffer. This means that if any device is active in a single FIFO system, no other device can be accessed or do anything until the initial device has completed its task
Dual FIFO
In dual FIFO, each IDE cable (channel) has its own, independent buffer. This means that in a dual FIFO system, two devices can be operating concurrently, and will not experience slowdowns or problems as long as they are on separate channels. They each have their own buffer that works independently of the other.
Single FIFO systems can experience slowdowns, especially when there is a slower device on the channel. If a hard drive and a tape drive are on a single FIFO computer and the tape drive is issued a rewind command, the hard drive cannot be accessed until the tape rewind is complete. If the operating system’s swap space is on that hard drive, the system will appear to hang if a swap is required. This is because IDE does not allow a function of disconnecting and reconnecting to a task like SCSI does.
*conclusion*
Best to keep the burner and reader on a seperate channel, and have a system that supports Dual FIFO!

CD-RW media has a much lower reflectivity than CD-R or CD-ROM media. It is so much lower, in fact, that standard CD players cannot recognize CD-RW media at all. Currently, the only devices which read CD-RW media are CD-RW drives, CD-RW-enabled CD-ROM drives, or MultiRead-capable devices.
Copying audio digitally from a CD requires a CD-ROM drive or CD recorder which supports digital audio extraction (DAE). All CD recorders can perform DAE. Many CD-ROM drives do not support DAE at all; others do it, but not very well. Few (if any) high speed CD-ROM drives can extract audio successfully at or even near their top-rated data speed.
Unsuccessful audio extraction is easy to detect; it sounds bad (clicks, pops, or hissing within the track). The most common reason is that DAE is being performed at too high a speed for your source CD-ROM or CD recorder to maintain proper synchronization of the audio data it is passing to the hard disk or CD recorder. Audio samples are skipped or repeated, causing errors which sound to the human ear like clicks, pops, or hiss.
The solution is to slow down DAE. However, with some drives, getting a clean audio extraction requires reading at very slow speeds. Sometimes the drive will go back and re-read the same audio samples over again to make sure that everything is in the right place. At times, the read will be so slow that it is impossible to copy directly from your source audio CD to the CD recorder, because the read speed is slower than the recorder's write speed. In this case, you will have to copy the audio tracks to hard disk and then record them back to CD.
*conclusion*
If copying to the HDD first, keep the burner and source HDD on a seperate channel, and have a system that supports Dual FIFO!
A buffer underrun error means that, for some reason, the flow of data from hard disk to CD recorder was interrupted long enough for the CD recorder's buffer to be emptied, and writing was halted.
If you have more than 16 MB of RAM, change the hard drive's Typical Role to Network Server. This gives the HDD a higer priority than other devices, and should allow a clean fast transfer of data to the burner's buffer, reducing the underrun chance of error

What is your source device? A friend of mine NEVER had a successful burn when he used his DVD drive as the source drive. The laser was picker in the DVD drive, so his burn was screwed up everytime.
On a lighter note, he always had plenty of coasters when I came to visit http://www.sysopt.com/forum/smile.gif
