    What is in the drive that displays the error? Is it a known, formatted CD? Is the drive a R/W CD drive? Did you write your own drivers? What operating system are you using? How have you created your software to make the first drive bootable? What is in the 2048 bytes that you transferred?

Working In AVR32 Studio PLATFORM (ATMEL Controller).In my project, i want to create 4 LUN(PARTITION) for our Application Process (2 for CD-ROM & 2 for REMOVABLE),Now i created 3 LUN(1 CD-ROM(BOOTABLE) & 2 REMOVABLE) & it been ENABLE & Working properly .But 4th (cd-rom( NON BOOTABLE )) is not been readed .I don't know what changes to do in code i do all changes but i didn't get output.If you are free please can u check my code & suggest your ideas to solve this problem sir.

    Sorry, I am unfamiliar with that application and the AVR. I was thinking along the lines of the physical hardware and/or media not being writeable ("CANNOT BE FORMATTED" error message).
