Sence Codes And Buffer Underruns


saltnpepperjazz

Question

THERE WAS A

 

 

SORRY!!!!

Buffer Underrun was not spelled correctly in the first communication

 

I have a PowerMac G4, 1.25GHZ

768MB of Ram

OS 10.3.9

Lacie D2 Lightscribe DVD Burner

Toast 6.1.1

 

 

When I attempt to burn a CD/DVD +or-, the burn stops at some point between start and finish.

I have lowered to speed to 1x, checked off the buffer underrun feature and I still get the

following error message from the toast software:

 

"The drive reported an error

sense key=illegal request

sense code=0x21, 0x02

buffer underrun.

 

Thanks for taking a look see, I hope that someone has a

solution they might share.

Thank you for the help, I will try your idea.....

 

 

 

After the download of the combined OS10.9.3, I was able to burn a CD.

when I attempted to burn a DVD, I got a different error message:

 

The drive reported an error

Sense Code Key=Medium Error

Sense Code=0x0C

WRITE ERROR

 

I remember reading somewhere in The Community about trying

different hi quality DVD blank discs, until you find one that works.

There was also a warning about Memorex, well it was an 8.5GB

DVD+R Memorex that prompted the new error message. I am on

my way to seek those other topics,

 

Thanks Again

I'm not sure what would cause buffer underrun errors regardless of whether you burn CDs or DVDs. Since this is a Firewire drive (right?) it could be a problem with the OS. It is too common that incremental system updates (such as from 10.3.8 to 10.3.9) can cause bizarre USB and Firewire behavior. The fix is to download and apply the Combined System Updater from Apple's support site. You'll be installing the 10.3.9 combined update on top of your existing 10.3.9. My hunch is this will fix the problem.

Moving Right Along...

Even after employing Verbatim media, there were still a FEW

glitches using Toast 6 with the Lacie Firewire DVD burner...

 

I replaced my Seagate 80 GB boot HD/2MB Buffer with a Seagate 320GB HD/16MB Buffer

Installed an internal Pioneer DK 111 DVD burner in the empty optical drive bay, dis-connected

the Lacie Firewire DVD burner.

 

I NEVER HAD ANOTHER PROBLEM, (Over 60 DVD's,) Burning DVD's, NO COASTERS!!!!

 

Not Put Down On Lacie, Just Sharing A What Happen...

 

Happy New Year

 

 

 

 

 

 

PS,

I Have burned SEVERAL Memorex DVD+R DL disc's

The new set-up seems to have no objection to the

DVD DL brands I have used which are;

Verbatim

TDK

Memorex
