[nflug] CDROM backup problems

[Joe]

I have a backup script for my system which makes image backups of all my 
partitions using dump for the Linux ones and partimage for the Windoze 
98se ones.  It makes the files in 600MB chunks for CD burning and saves 
them to my big secondary hdb1 drive.  That works fine (and has for a 
long time).

Now, I am writing a second script to run all of them through mkisofs and 
cdrecord.  The script is fairly well tested - with these two main 
commands commented out.

Now I turned them on and got problems with cdrecord on the first 
iteration (it looks like mkisofs worked).

Questions:

Do I need to use different parameters for mkisofs for the Linux 
partitions than for the Windows ones?

Do I need to do anything about "Rock-Ridge" extensions?

Why is cdrecord unhappy?

I am (still) using Mandrake 9.1.

I did put a new blank CDROM 16x 700MB in the CDRW drive before I started.

Thanks.

Part of script that makes the iso and burns them (in a loop of several 
iso's)

mkisofs -J -o ${IMAGES[$I]}.iso ../${IMAGES[$I]}
  STATUS=$?
  if [ "$STATUS" -ne 0 ]
  then
    echo "Could not create /mnt/portable/iso/${IMAGES[$I]}.iso"
    mkisofs returned $STATUS
    echo $SCRIPT aborted
    exit 1
  fi

  cdrecord -v -speed=4 -data -dev=1,0,0 ${IMAGES[$I]}.iso
  STATUS=$?
  if [ "$STATUS" -ne 0 ]
  then
    echo "Could not burn /mnt/portable/iso/${IMAGES[$I]}.iso"
    echo cdrecord returned $STATUS
    echo $SCRIPT aborted
    exit 1
  fi
