Re: dvd+rw-tools multisession recording fails after a few sessions

Hi,

i would say the media is worn off by too many
write sessions.

95 sessions is not "a few".
Rather "quite a bunch".

Is 95 a realistic count ? Did you do as many ?

4 3E 02 is SCSI error TIMEOUT ON LOGICAL UNIT

0x54 is MMC command SEND OPC INFORMATION.
This is a typical preparation command for writes.

3 73 02 is SCSI error POWER CALIBRATION AREA IS FULL


growisofs 5.21 and mkisofs 2.0 are old, indeed.
But i would not blame an OPC error on them.

This seems rather ito be a question of drive and media
compatibility resp. quality.


Have a nice day :)
