Lion doesn't read mp3 cds?

post #1 of 14
Thread Starter 
Hi.

So I got some cds laying around here which I used a couple of years ago to back up some of my music. I was backing them up to an external HD when I was on Snow Leopard. I had no problems at all, I would just pop the cds into the drive and copy paste the folders with all the files to my external HD.

But on Lion I can't do that. When I try to copy I get a message saying "The items on the Clipboard can't be pasted to this location. One or more of the items may have been deleted or are no longer available." and I only get an OK button. When I go to the CD icon on the desktop, I double click it and a window pops up where I can see the folders, but there are no files inside any of the folders. Using Command+I shows that the folders are 0 bytes...

This happens on my 2008 20" iMac and on my 2010 15" MacBook Pro. I then decided to pop the cds on the drive of my father's Windows 7 Compaq and the files appear and I can even listen to the songs too.

Anyone has any clues on this issue? Thank you for any help you can provide...

Well unfortunately I don't think that's the case, because as I said I can view the files on my father's Windows 7 Compaq and I was even able to listen to some of the songs there (I didn't try them all obviously).

Besides I didn't come off Snow Leopard that long, the last time I used those cds was about a couple of months ago and there was no problem with them back then...

Of course it isn't the case; he's making up crap to spread FUD.

What happens when you try to rip the discs into iTunes?

Nothing happens. iTunes doesn't recognize the Cd (I believe that's because it's full of mp3 unlike a regular music cd). And since it doesn't recognize, I don't get the "Import CD" button.

When I try to add the songs manually (via File > Add to Library...) nothing happens either :S

I just did some extra testing.
Regular audio CDs work ok (both Original and copied).
I also tested with a DVD I had which is full of mp3 files and it works too.
Only CDs with mp3 don't seem to work.

Again this happens on both my Macs...

EDIT: IT doesn't seem to happen with all the CD either...this is weird. But the ones that don't work, work fine on Windows 7 and worked fine on Snow Leopard :S

Maybe its a bug. Report it.

Then use your Win 7 box to copy the music to your Mac

Wow... Parttimer... just wow.


I'm gonna venture a guess here.
Were the mp3-CD's burned on a Windows computer?
I'm guessing they were... and the sessions were not closed out "properly"... so the discs don't meet the CD "spec"...

Most windows software is aware of this "feature" of windows CD-burning and can work with it.
OSX has never supported this "feature" (since it's not part of the "spec") and therefore can't read it.




really, Parttimer?... really ?!?!

Parttimer right on the first post I thought you were trolling me, but stupid me actually kinda took the bait. You must like chemistry a lot to go on and mention osmosis as a reason for my problem. Pity CDs aren't made from water yet...

KingsOfSomewhereHot, yes they were burned on a Windows machine but I can't remember how I left those sessions. But it's still odd though, when I had Snow Leopard I could see the files on them, and I did copy the contents of a couple of those CDs to the external HD back then.

I just grabbed some of the CDs that I know that worked on Snow Leopard and tried them here and I had the same result, I can view folders, but no files. Maybe they changed the way OSX handles sessions?

I missed that part about them working on earlier versions of OSX ... But I still think that's a more likely explanation than osmosis! (it's hard to even type that without laughing out loud!)

I cannot vouch for Parttimer's use of the term osmosis, but his explanation is largely correct. Commercial discs use a thin aluminum film into which the content is pressed as microscopic pits. The pits alter the reflection angle of the reading laser. Home burned CDs and DVDs use a completely different method to store content. Instead of a thin film of aluminum, these discs have a thin film of optically-sensitive material. The laser in the write head of the burner changes the phase of the material, creating little phase change spots that correspond to each bit of content. Unlike the aluminum film of commercial discs, there is no mechanical change to the medium. However, the laser of the reader has different reflectances for the phase change spots than for the spots without the phase change.

Parttimer may be overly generous in his assessment of the durability of commercial CDs. The aluminum film is fairly durable, but the plastic carrier is plastic. Plastic deteriorates over time. That is the nature of the beast. I would hope that a commercial CD lasts twenty years, but I am taking no bets.

Home burned discs, however, are a whole different game. Blank discs vary from model line to model line. Some burning heads use higher powered lasers which will result in greater phase change in the sensitive film. Some read heads on the reader/player are more sensitive than others. But the part that you cannot escape is that the data are recorded by light and can therefore be destroyed by light. My personal experience with CDs is that they are actually fairly durable. DVDs are a whole 'nother ball game. The phase change spots are substantially smaller and substantially less durable with DVDs than with CDs.

Home burned CDs should receive minimal exposure to light and DVDs, none at all. My experience with DVDs told me that the notion of archiving my data on Blu-ray was a pipe dream. Afterall, Blu-ray phase change spots are even smaller and less durable than DVD phase change spots.

Call it osmosis, call it banana. The bottom line is that data archiving on optical media is a short-term and unreliable proposition.

I think your best bet is to use a USB stick to transfer the files from the CD from your Windows computer to the Mac. It could be the drive firmware, Lion, or the Mac not "liking" the burnt CD for whatever reason. Not much point wondering what went wrong.

um... no. You're not even close.

Osmosis is the use of a semi-permeable membrane to allow certain solvents (depending on what's used as a "membrane") to pass through, while not allowing other molecules through. Solutions of different concentrations, separated by the membrane, will allow the solvent to pass through in an effort to try to equalize the concentrations...

"Good ol' red rust" is an example of oxidation, not osmosis... two VERY different things.

It's a shame Parttimer doesn't know what the hell he's talking about when it comes to osmosis, because it casts doubt over his credibility and makes people less likely to pay attention to the meat of his message, which is entirely true. Home-burned optical disks do not last very long!

If you want more evidence than that little PC World article, I'm sure Google and Wikipedia between them should satisfy you.
