I just burned a cd at 4x and it worked. Hopefully a slower burn speed is the solution for most folks
Burning faster than that can easily create burn errors/coasters. I've always set it to about 2x and have never had a problem - having a DVD take 3 more minutes is insignificant.
Really!!!???
Seriously???!!!
If the CD disc and the burner drive can suppot it, should be able to burn, at least, CDs faster than 4X!!
My LaCie CD/DVD optical drive supposedly can burn CDs up to 48 X speed, although I have never tested this at that speed. I have burned CDs sometimes, in the past, at 24X speed and the data was fine and perfectly readable.
I can burn CDs stably/reliably at 8X and 16X times speed. I, usually, burn my CDs at 8X speed, if they are not going to be like an archival style disc.
DVDs, typically, burn at slower rates than CDs.
If I want a more permanent data disc or archival style disc, I usually burn either 2X or 4 X speed for that type of data disc.
I do not how much knowledge you have about how burning discs of data work, so I'll try and keep this as brief as I can.
There are two different lasers in a CD/DVD read/burn optical drive. Also, the elastomeric dye layers on CD/DVD write discs are different dyes and colors, but the method/procedure is the same.
When burning data to an optical disc, the lasers doing the burning heat up the dye layer leaving a dark spot and slight deformation of that darkened dye layer spot or pit of data.
The faster you want to burn the disk at, the less amount of time the stationary laser stays on a particular spot on the disc and the heat generated from the laser is less causing a lighter spot of "burned" data to appear on the disc.
The slower the disc spinning rate the darker and more deformed the data spot/pit will be making a more lasting impression (excuse the pun) on the disc creating a more permanent mark of data on the disc.
For data burned at faster discs speeds above, say 16 X speed, The drive may read the data for awhile as the read laser strength can cause a disc that has been burned faster and leave lighter data pits to fade faster and, eventually, data will not be able to be read any longer from a faster burned disc.
If you want to burn and keep, long term, archival data discs, these should be burned at slower speeds to affect the dye layer more permanently to keep those dye spots/pits as dark as possible and the deformations in the disc dye layer for much longer periods of time.
That stated, most combo CD/DVD optical burning drives should be able to make a reliable reading CD style disc at speeds much faster than 4X speeds.
If I am making a DVD movie DVD, my drive can only burn these up to 8X speed. I,usually burn DVDs at 4X speed.
Even for data archiving, I burn the DVD archival data discs at 4X rotational speed.
