I am writing files to a DVD with growisofs once a day. Each time I append to the DVD, I have to eject the DVD and then re-load the DVD in order to see the file I just wrote. I am using RHEL 5.0 and to initialize a blank DVD, I use the command:
growisofs -Z /dev/dvd -rJ -use-the-force-luke=notray file1
which will write file1 to the DVD. Next, I will try to write file2 to the DVD (without ejecting the DVD in between) with the command:
growisofs -M /dev/dvd -rJ -use-the-force-luke=notray file2
and that will fail with the error:
"/usr/bin/mkisofs: Invalid argument. Seek error on old image
: - ( mkisofs has failed: 22"
If I eject and then try the growisofs -M command again, it will successfully write file2 but if I try to write file3, file3 will fail with the same error.
I remember reading some where (might have been a man page) that in between burn sessions you might have to eject and re-load the DVD, however, I did not have this problem with non-Blue-Ray compatible drives.
Even if this is a problem with the Blue-Ray drives I have been trying, is there a way to simulate an eject without actually ejecting a disc? Or some other way to work around this without having to physically eject the DVD? I can't do an eject -T because it is a laptop drive, so the drive cannot close under its own power.
Any help or ideas would be greatly appreciated. I have looked at ioctl commands such as:
ioctl(file_descriptor, CDROMSTART) ioctl(file_descriptor, CDROMSTOP)
but I haven't looked at many other commands or found a command that solves my problem... yet
