Hello !
Je teste un graveur DVD tout neuf.
Reconnu  au premier boot,
...
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
   Vendor: LITE-ON   Model: DVDRW LDW-851S    Rev: GS0F
...
je fais l'image iso en me plaçant dans /tmp :
mkisofs -exclude-list exclus -o her-bak.iso -R /home/her
un montage loop pour vérifier : OK
l'image iso fait : 1.235 Mo c'est peu
puis je lance la gravure :


/tmp# cdrecord dev=0,0,0 speed=2 -v her-bak.iso

cdrecord: WARNING: Data may not fit on current disk.
cdrecord: Notice: Most recorders cannot write CD's >= 90 minutes.
cdrecord: Notice: Use -ignsize option to allow >= 90 minutes.
cdrecord: Cannot write CD's >= 100 minutes.


Aï ! Comment dépasser cette limite ?
man cdrecord :
-ignsize
               Ignore  the  known size of the medium. This options
               should be used with extreme care,  it  exists  only
               for  debugging purposes don't use it for other rea­
               sons.  It is not needed to write  disks  with  more
               than the nominal capacity


le DVD est un Verbatim 4.7 Go, l'image fait 1.2Go
je rajoute l'option -ignsize, et j'ai la même alerte !!
Un problème de driver :
"Using generic SCSI-3/mmc CD-R driver (mmc_cdr)."

Merci de vos lumières !
