A week ago I bought my dual 1G G4 (what is the common nickname for this machine?). Last night I was playing around with CD burning. With a fairly full CD, I get an error copying it to the hard drive. It would manage about 440mb out of 460mb. Then I dropped the CD itself onto Diskcopy and after about the same amount of time, I get this error "Image Volume operation failed with error 999 (internal error). This happened on 2 different CD and it so far seems to happen only one ones that are fairly full. The one thing I haven't tried is hooking up my older USB CDR drive and try and do a direct copy from drive to drive. Any ideas? What I saw in Apples KB pertains to an older version of Disk Copy.
