Burning and Erasing CD-RW discs in OS X

I was having issues burning a CD-RW on my Mac. I first tried formatting the CD-RW using disc utility and that didn't work.

So I tried a different brand and that did the trick. I was originally using a Memorex CD-RW and switched to an Imation CD-RW. When I put the CD-RW in, OS X mounted it immediately. I was able to drag files to it and burn them.

As a test, I went into Disk Utility (resides in Applications -> Utilities folder), I looked in the tree under my DVD-ROM and it said "Session 1" then under that said "Untitled CD", I clicked on "Untitled CD" and clicked the erase tab. I erased the CD-RW with no problems.

I then dragged about 300mb worth of files onto the CD-RW and it re-burned just fine.

I am using a Macbook Pro Intel Core 2 Duo running OS X 10.4.11 with a MATSHITA DVD-R UJ-857D burner.

Note: When I purchased my Macbook Pro I was having all sorts of burning issues with CD-R, DVD-R, etc... so I took my mac into Apple and they replaced my Super Drive for me.

So if you are having issues after trying Imation CD-RWs, then it could be your burner. From experience, these Super Drives can be problematic.

yep and thats a good idea, I put a deck capable of playing mp3s in my car also it helps alot if you get cd-rw`s they cost just a tad bit more but are worth it in the long run.

You are definitely right Cody, the reason for the CD-RW was to play songs in my truck, I have a stereo in my truck capable of playing CD-RW mp3 disks, so I figured I could just keep re-using the same disc when I want new songs on it.

Interesting stuff to know although I do not use macs other than at the school when I absolutely have to.

Something else you can do is just buy an external drive that does whatever features you`d like it do that way you can swap it out between multiple computers if needed but it helps if you get ones that are capable of using eSATA AND usb for speed reasons.. usb would be used on laptops but some laptops now are starting to have eSATA on them. but it saves money so you do not have to buy for each individual computer also you can take it with you even somewhere to a friends house if they have something you want to burn to a disc but they do not have the drive required to burn to like a DVD and they only have a CD-RW the technological advances that we have today are phenomenal I will say that.
