why won't iMac play any cd or dvd RW discs but fine with normal discs?

Please help!

IMac won't read any dvd-rw or cd-rw discs but will happily play cd-r's,dvd-r's and official film dvd's.

im assuming this has to be a software issue as it will play other discs?

I have a 27in mid 2010 iMac 3.2ghz i3 with 8gb on Yosemite 10.10.2

HL-DT-ST DVDRW GA32N: Firmware revision KC12

i also have a 21.5in late 2009 30.6ghz intel c2d which I'm selling which runs all the discs fine!!

HL-DT-STDVDRW GA11N: Firmware Revision JA18

Any ideas???????

Thanks

Oli

iMac, OS X Yosemite (10.10.2), 3.2 i3

2 possible solutions.
- Try using top brands of CD RW and DVD RW. I used to buy cheap CDs and DVDs and a lot of them didn't work. I changed to Phillips and Verbatim and no problems.
- Close the recording session before using the disc. This is a common problem when using Windows, and perhaps in OS X has the same problem.

Good luck.

Thanks for that, I have tried many different brands (top and cheap) of cd-rw and dvd-rw's but none work on the 27in mac. these all work on the 21.5in which is slightly older with different firmware. Also, I'm not trying to burn cds, just read them would be a bonus.

Thanks
