Re: I/O errors when writing DVD+R using growisofs

When growisofs starts to run it spits out a few errors that are
recorded in /var/log/messages & also takes about 10 seconds to
recognize the size of the iso image so that it can give an estimate of
how long the command will take to finish.
The /var/log/messages errors are:
kernel: I/0 Error: dev 0b:00, sector 64
In the beginning of every recording growisofs performs an overwrite
check. As the media is blank, attempt to check resulted in I/O errors.
Yes, it's meaningless to check blank media and this deficiency was
addressed in 5.15 [which is why I wrote "result*ed* in I/O errors].
Either upgrade the toolchain or simply disregard the errors (as they
don't affect recording, essentially they are simply warnings). A.
Thanks for the explanation. I had noticed that the data on the DVD+R
disks was perfectly fine, but the errors had perplexed me.
