I/O errors when writing DVD+R using growisofs
I'm getting some errors when running growisofs, although the data on the
DVD+R disk appears to have been written correctly when I mount it and
check the data.
I'm using the following:
- TDK indiDVD 420n internal IDE drive
- DVD+R disks
The commands I'm running are:
The variables used below are set.
# mkisofs -r -N -L -d -D -V "$company" -A "$company - backup created on
$today" -P "$company" -p "$company" -x lost+found -o image.iso dir
# growisofs -Z /dev/scd0=image.iso
The image.iso size is approx. 3GB (3,000,000).
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
kernel: I/0 Error: dev 0b:00, sector 68
kernel: I/0 Error: dev 0b:00, sector 72
kernel: I/0 Error: dev 0b:00, sector 76
However, there are no errors when I mount the disk after burning and
I've searched using google without much luck on finding the source of
What could be causing these errors?
Is it likely a software issue or could there be a problem with the drive?
If the data appears to be burned to disk correctly, then can I safely
ignore these error messages?
Thanks in advance,
