Hi folks,
i have hacked a small testprogramm which keeps the cdrom spinning under
certain circumstances.
preparations:
1. /etc/init.d/gdm stop
2. pkill hald
3. /etc/init.d/fam stop
Tests
case 1:
Action
1.1 Insert a data CDROM
1.2 start halTest
1.3 wait until program terminates
Expected Results
nothing happens, drive remains silent
case 2:
Action
2.1 start halTest
2.2 while halTest is running:
open and close the cdrom tray (with data cdrom)
2.3 wait until porgram terminates
Expected Results:
after opening and closing the tray, the drive starts spinning and
continues to do so.
The drive stops spinning aprox. 14 secs after issuing the last close.

/* It seems that opening and closing the device in a nanosleep */

close(fd);
usleep(1000000);
counter++;
if ((counter % 40 ) == 0) break;
}
for (i=20; i>0;i--) {
printf("halTest.main remainig time to exit %d \n",i);
sleep(1);
}
}
######## end testprogramm #####
Merry xmas and a happy new year .
