Input/output error

With CD recording software, errors like that usually mean that for some reason it failed to write to the drive. There are many possible reasons for that, some of which are listed below (I realize some of them are very obvious -- hopefully you're not offended).

If it doesn't record at all, it could be:
- The software is not setup to use the correct device
- The user running the software does not have write permission for the device (should belong to the "cdrom" group)
- The drive is not a recorder
- The CD is not blank
- The CD is not the proper type of media (e.g. DVD-R in a CD-RW drive)
- Software bug
- kernel, udev, etc. problems (not likely here, unless they've been played with)

If it records sometimes, or records part of the disk and then gives the error:
- Bad disk
- Dirty disk
- Failing drive
- Media that does not work well with that drive, or at that speed (try burning at a lower speed)
- Buffer underruns (try running less other software while burning)

Is that the entire error message? If there's more, that would help.
Also, does other recording software work properly, or do you get errors like this with everything?

It's also possible to get an error like that for other reasons, such as being unable to access a file on the hard drive, but it's less likely.

i/o errors are usually speed or program errors. Try burning at a lower speed or upgrading InfraRecorder.

I've verified all those steps but it still does not work. It says to verify the log.

It says : input/output error.write_g1: scsi send cmd : retryable error.
Input/output error.read buffer cap : scsi send cmd
Verify the log

Here's what the log says :

Finally it's working. The program Infra Recorder had a bug so I downloader iso burner and it went well.

Thanks for your help.
