Medium write error!!!

[ilvtofu]

hi everyone, first time on this part of RS
Hoping someone can tell me what's wrong

I'm using a 20" mac with a 2.66? GHz and 4gb ram
bought it last august.

Neways heres the problem
I'm on itunes and i'd say a good 50% of the time,
when i want to burn a CD it tells me "medium write error" and when it's 99% done it spits out the CD
So when i stick it in a CD player, the last track is just disappeared sorta or skippy.

I'm just using regular Sony CD-Rs from costco and they have a recording time of 80mins, the CD i wanted to burn was <75 mins, so i thought it'd be fine. I burn it at 4mb/s? and not the maximum speed. Same thing happens only 12/13 tracks are burnt onto the CD.
The 12 that are burnt work fine though.
This happens all the time and i'm going through CDs pretty fast.

PLZ!!!

update the firmware on your drive. buy better/different CD's. some cds just are not compatable.

lower your burn speed to about 8X

[skholla]

at 99% eh? thats when its trying to close the disc. as others have said, try a different brand of disc and also try a lower write speed. if that doesnt work then give apple tech support a call and ask for help, they will probably book an appointment for you to take your mac to the apple store to have the drive swapped.

Yeah, I actually think that's a hardware problem with the burner.

when your dealing with a mac call their tech support

I've seen this before.

The laser portion of the drive for burning is defunct. Call up Apple to proceed further for instructions on warranty issues.
