Hello, I am hoping to get some help with this frustrating little toas
malfunction.

Computer
G5 OS 10.3.9.
Software- Toast 6 titanium

I am in the process of backing up my files to DVDs and I get thi
error:

The drive reported an error:
Sense Key = ILLEGAL REQUEST
Sense Code = 0x21, 0x02
BUFFER UNERRUN

then it allows me to click OK and then it says disc failed to write.

I tried burning the disc at 4x, 1x, Mac only DVD and DVD-ROM

I don't know what else to do. I keep on wasting discs

Thanks T

Can you update your software? I use 5.0.2 with no problem. Are you
burning a file that is on your desktop or on an external drive.
Perhaps you have bad media?

Turn off bittorrent downloads while burning. :-)

Seriously, thrashing the hard drive (with any software) while
trying to burn can cause this problem, particularly with a slow
drive. Sadly, the OS X file system is in need of some
performance tuning on single-drive volumes.

Buffer undderrun means that you computer isn't able to feed the burner at
the rate it needs data to burn the disc. - The burner first heats up the
track, and then it must have the data to be burned available immediately.

One remedy is to have a disc burner with under burn protection. Another is
to make sure that the computer is able to feed the information
sufficiently fast. If the data is on a slow hard disk, you may copy it
over to a fast one and burn from that.

One way to make faster burns is to make a disc image in "Disk Utility" and
then burn that one.

You may also use RW discs to avoid trashing discs.

This is the first time in years that I have heard of anyone having this
problem. In the old days if a burner temporarily ran out of data to
write it would have trouble finding the exact spot where it left off and
the disk would be ruined. Years ago this problem was fixed so I find
your problem very odd, especially since you tried burning at 1x, which
should obviously make it easy keep up with the burner. IIRC, 1x should
be about 1.3 meg a second and if your hard drive can't do that it must
be a billion years old.

Here are some things worth trying:
- check the toast prefs to see if "buffer underun protection" is turned
on. note: if your burner is a billion years old it will not have BUP.
- go to the toast prefs and set the RAM cache to the largest size
possible.
- turn off all the other apps
- compress all the files into a single archive. If you have a lot of
disk space this should put all the data into a continous disk section
and make reading easier for the computer.
- try running in simulation mode to see if toast reveals any important
info through that.
