Emac - running OSX 3.9 purchased October 2004
External LaCie DVD burner (USB and Firewire) purchased June 2007
Initially I had a problem trying to burn DVDs to the external LaCie DVD burner - the DVDs wouldn't burn giving me these error messages:
Buffer underrun error. Writing was halted because data could not be sent to the recorder fast enough to maintain the current write speed. Please try again with a slower write speed.
-50 interface error the connection is not stable
Iíve tried (unsucessfully):
Using different types of blank DVDs both RW and R
Writing at the slowest speed possible x1 and x2
Burning from Toast, Finder, Iphoto
I even tried re-installing Toast
I also tried attaching the DVD burner to a PC Ė it burnt the DVD but didnít verify it sucessfully.
12GB of space are free on the Hard Disk so there should have been enough space to burn the DVD.
I then remembered that in the past the emac has once in a while had problems burning a CD but on a second attempt itís been fine.
So I then tried to burn a CD using the emacs internal drive. I tried three times with no sucess and these messages:
The drive reported an error sense key medium error sense code OXOC write error
2nd time: Sector 623 is unreadable verification failed
3rd time (after burning a cd in Itunes) when I try to play it I get the message No volumes that the mac can read.
I am now worried that it is more serious than something to do with the CD or DVD burner.
Thanks in advance for any advice.
