I have disks burnt commercially on a windows system, which my 2010 iMac (OS X 10.8.2) refuses to read.
I know the disks are correctly burnt for windows (tried them on the vendor's win machine - probably xp) but os x says:
"The disk you inserted was not readable by this computer"
I've no idea what to try (short of accessing them on an at work win machine. Any pointers out there?
