My i-mac can't read commercial CDs -

after attempting to read them, they are ejected. recordable CD's work ok, so it doesn't seem to be an driver problem.
I running O/S lion and the Imac is about 4 years old.
anyone help with this please?

I suspect part of the drive is giving out, Rad & Write use different voltages & circuits. CDs & DVDs also use different Lasers.
Only a couple of things to try...
One of those Cleaner CDs.

Is it possible for a mac to run across a Windows based server such as in a school, and still be able to access all networked folders? I have been told that macs can only read down a certain number of folders

Is it possible to run a mac on a windows based server? We have a server based on Windows 7 in our school, and our techies are reluctant to let me buy a mac as they say macs can only read a number of folders deep, which would preclude me from accessing shared folders on our servers. Is this true, and is there a way round this? I would eventually like to get a suite of macs, but because all our resources are on the server, I have to be able to access them.
Thanks for any help,
Mike

I have found that both Linux and Mac (unix) are capable of reading "deep" folders while win 32 will have issues, your it people are clearly wrong. I run a network with both win/mac. And as long as the win servers/pc's that have shares are set to allow apple file sharing in their folder properties. And the macs are set to allow smb there should absolutely no trouble with you accessing anything across the platforms, heck, from a Mac to a win pc on some occasions you don't even need to include a "domain" name to log on to, and you can create aliases and make your own shortcuts etc... So you don't have to manually connect each time you boot up etc... But that's all personal preferences I suppose.
All I can tell you is that, I do it on a daily basis managing a small business. So your answer is yes you can.

Can't read data CDs after upgrading to 5.0

After upgrading to 5.0, I can't read data CDs I've already made from any other programs. When I try to open one, Windows Explorer shows D: drive with no folders or files at all, and 0 bytes used/0 bytes available. I can still play DVDs and audio CDs. iTunes 5.0 opens fine on pc, and I can access/play music, but doesn't recognize my iPod or iPod mini. I'm afraid to download anything else until I get this problem fixed. HELP - please
I've used System Restore to go back to earlier version, and that lets me view/use CDs, but I can't open iTunes - message says some files missing, reinstall iTunes. I've tried to uninstall iTunes through add/remove, but the install shield disappears after starting.

hi Jeanne!
Problem is obviously a software conflict, but I'm lost on how to fix it. And it's getting tiring installing upgrade to use iTunes, then going back to System Restore in order to back up data from other programs - plus I can't believe that's the best thing to do for the pc.
gaah. okay, the fact that a Syetem Restore gets your CD drives back suggests it's a registry issue, and also that we're either getting a conflict with other installed non-MS burning/ripping software
b or
(unfortunately), there is a problem showing up related to such software that you've
b previously uninstalled,
but which has left behind some peculiar registry entries.
so let's try attacking both the ghosts of software present and past.
(1) what other burning/ripping software do you currently have on your PC? can you go into your "about" screens in the packages to let us know the precise version name and number? (the decimal points do make a difference, i'm afraid.)
(2) here are the standard MS troubleshooting documents on CD drive problems. it might be best to start with the
b burning
KB doc, because that has probably the best information/links on the conflict issues:

keep us posted.

Mac can't read a Windows CD...

I downloaded a couple of Mac OS X updates on my Vista PC, burned them onto a CD (type CD-R) and took them to the Mac. After spinning up the CD, the following msg appears: "You have inserted a disk containing no volumes that Mac OS X can read. ......."
I used the "mastered" burn option - as that claims to have the best compatibiity with other systems.
What do I need to do to ensure the Mac can read the CD?

Because I chose the "Mastered" format, there is no option to close / finalise. Here is a relevant description from Windows Help:
"Mastered discs do not need to be closed; they are automatically compatible with other computers, so you will never see an option to close a session that you have made with the Mastered format."

Itunes can't read commercial cd's

since a couple of weeks when trying to add a commercial cd to the music library, itunes is trying to read the cd but after a short time ejects the cd. this happens 7 out of 10 times. never had the problem before. any tips?

I have the same drive installed in my Windows PC, along with a Plextor PX-230A. I use the Plextor for ripping audio CDs, as there is no better drive for this, but the NEC is very good as well--super reliable and VERY fast, but can't recover from errors nearly as well as the Plextor.
With any Mac other than a Power Mac or Mac Pro, using an external optical drive is definitely the way to go for anyone even half-serious about ripping audio CDs. This also comes in mighty handy for those who buy the new MacBook Air with no optical drive at all

PDF File downloaded from Mac Can't Read From Windows 7

Hi,
I am now doing a research, and every time when I copy the reference paper in PDF format from Mac to a flash drive, it could not be read from Windows at the university lab. Usually some pages of the file was missing. This really cause me a pain. Please help me. Thanks...
Max

Almost all flash drives are formatted as a Windows drive. When you copy almost any file to the flash drive two different files are created. One corresponds to the data fork of the Mac file and the second is a resource fork. When viewed from Windows the resource fork has the same name as the original file but it preceded by a period. This resource fork file should be ignored. The real file as far as Windows is concerned is the data fork file.
Now if the file you are moving to Windows can be opened and is missing pages, then that is not the fault of Reader or the Mac OS. But is related to how you are creating or obtaining the file.

Moving iTunes Folder to a new Mac, Can't read iTunes library.itl

I'm replacing a Mac Pro (2,1) with OS 10.7.5, iTunes 11.4 with a 2012 Mac Mini with OS 10.9.3, iTunes 11.1.5. When I move the iTunes folder containing the iTunes Library to the new Mac, I get the error message "the file iTunes library.itl cannot be read because it was created by a newer version of iTunes", which is of course true. I really don't want iTunes 12. Is there a way to move iTunes 11.4 from the old Mac to the new Mac?

Hi, gokart-mozart.
Thank you for visiting Apple Support Communities.
You will need to rebuild your iTunes library file in order to open an older version of iTunes. Below, I have included the article that walks you through this process. Start with the section labeled Re-creating the iTunes Library file.

Powerbook not reading commercial CDs

I've tried resetting the PRAM. I've tried deleting plist files. I've turned off "use error correction when importing audio cds" in itunes preferences.
It does, however, read "Johnny Cash Live at Folsom Prison." Seriously.
It also reads DVDs and CDs I've burned myself.

Mine won't read the White Stripes' Icky Thump.

If you use time machine to back up one mac, can you read it on another

I have 2 mac laptops and want to save the data off the old and use on the newer.

Mac can't read Mac burned DVD but a PC can. Why?

Need a bit of help, I have an archive DVD that was burned a couple of months ago. After the burn I checked to make sure all files were readable. ejected it and popped it back in and had no problems.
This morning popped it in and it wont mount. This was a working DVD a couple months ago. It has no scratches or finger prints.
It will not mount on any macs.
MacBook Pro
Mac Pro
G4
G5
imac and so on
here is the kicker, it WILL mount on a PC.
any thoughts or suggestions?

Had the same trouble a few weeks ago. Try repairing Permissions on your System drive with Disk Utility and restarting. That solved the problem for me.

How come a USB will work with both Mac and Windows (as in that there are already files from Windows and Mac can still read and write onto it) but a external Hard Drive won't (as in there are files from Windows on there but Mac can read but not write)?

I have a Seagate Drive that I'm hoping to copy some movies from my Mac onto (because it only has a 512 SSD and I'd rather keep that empty and handy for more readily needed files) but it won't work. It shows up as a drive when connected (with the orange USB drive icon popping up) and is appropirately labeled "FreeAgent Drive", but when I try to copy files onto it it won't work. There are already windows files on there, such as some windows backups and lot's and lot's of pictures and videos. However, I have several USBs which already have windows files on them (namely movies, music, and other stuff) and copying and stuff works fine. Why won't it work with this hard drive and would work with USBs? Please help me out here guys, I am not experienced with Hard disks and formatting and stuff like that. 10 points for whoever helps me out the most. Thanks.

We will need to reformat your EXT, but it will then work on both Mac and Win
Connect the drive to your Mac, open disk utility
Go to the partiton tab and select '1' ... format should be ExFAT ... in options select MBR
Format the drive
It should now work on both OSs; report back
