I could have tried 20x, But hey, I am in no hurry. It has always been set to maximum (24x, I guess.) What did I have to lose. I really figured it was about time for the optical drive to be replaced after having used it many a time over the years. Then I ran disk utility - all is working fine. I have checked other posts on the subject, cleaned the drive (I am a smoker so I figure second-hand smoke gunk in the drive along with dust and dirt since the opening is uncovered on the side of the all-in-one system). Then I switched over to iTunes to burn a music CD - uh-oh - same message. Same thing happened - the Miedium Write Error message. I tried different blanks, and switched to another brand. I am using an iMac5.1, 2 GHZ, Intel Core 2 Duo, when the drive took a dive while I was attempting to burn an IMovie on Christmas Eve. But I just have to tell you, I have been suffering with this error message for about a week. I just find the answer I am looking for and then go on about my business. Wow! DROP THE BURN SPEED! I generally don't respond to these. But I am really excited and just wanted to let you know how much I appreciated find your answer to my problem. But I had to join in order to submit, so forgive me if this is a double post. I don't know where I am supposed to mark accepted, and I don't know if my response has posted. If this Answer is helpful please remember to return and mark it Accepted. If none of the above possible fixes work you could have a damaged optical disk drive. Repair your startup disk with Disk Utility, in the Utilities folder in the Applications folder. Back up files you don’t use often, and then remove them.
The amount of free space on the startup disk needs to be greater than the amount of data you’re burning. If your startup disk is nearly full, try to free up space on it. Quit all open applications you’re not using. Use blank discs that are rated for the burn speed of your drive, or consider using a different brand of disc (excessively cheap or off-brand optical disks are known to have problems). Wipe the shiny surface with a soft, damp cloth, working from center to edge.ĭo not move, bump, or shake the computer while the disc is being burned. (try 1/2 that maximum speed )īE sure the disc is clean. In iTunes->Burn Playlist to Disc->Choose Options: Choose the option from the Preferred Speed pop-up menu, Change the CD recording speed, Specify a burn speed that is lower than the maximum speed rating for your optical drive. Burn speed is one of the possible factors related to this problem.
