Hi,

I am running Centos 4 (fully updated on this box).

I removed the old DVD writer (/dev/hdc) and installed a new LG GH20 "Internal Super Multi DVD Rewriter" with a SATA interface - this shows up as /dev/scd0.

When I insert a pre-recorded DVD autorun mounts it and displays the contents without any hassles. It appears to me that the required kernel modules are loaded - as copied below from lsmod output.

sata_nv                18629  0
libata                111261  1 sata_nv
sd_mod                 17217  0
scsi_mod              125261  3 sr_mod,libata,sd_mod

I am using Verbatim DVD-RDL blanks.

When I try to write a pre-recorded iso to the DVD I get the following error message:

[user@test]$ growisofs -dvd-compat -Z /dev/dvdwriter=<pre-recorded>.iso
:-( /dev/dvdwriter: media is not recognized as recordable DVD: 10015

I have tried to do this as root with the same result. /dev/dvdwriter is a link to /dev/scd0 and has full read/write/execute permissions.

Output of growisofs -version:

* growisofs by <appro@xxxxxxxxxxxxxx>, version 5.21,
  front-ending to mkisofs: mkisofs 2.01 (i686-pc-linux-gnu)

Any suggestions will be welcome - if any further information is required I will do my best to supply it.

I'm *really* a novice at this, but the first time I tried to record a
DVD (I use cdrecord) I learned that the media needed to be formatted
first. I don't know if what your using is already formatted, if your
software does it for you or if it's even needed.

Using the cdrecord software, there are flags that will let me know.

I have Googled with the error message but only get reports of this problem and no solutions.

TIA

Hi Bill,

Thanks for the quick response - I did try to format with dvd+rw tools but also got a respnse that the media was not recordable. AFAIK it should not be required.

From reading your many and interesting posts to this list I realize that we must be contemporaries (possoibly I started programming before you - circa 1963 on a ICL1500 aka RCA 301 in assembler or directly punching machine code into punch cards).

I do appreciate your responses as they always are helpfull and when them flame wars flare up you remain sensible.

Thanks again

ChrisG
