Re: cdrom_id (udev) causes "No disk in drive" warning for ide devices with removable media

Hi Kay,

thanks for your quick response.

It appears that the error message comes from drivers/ide/ide-floppy.c. Both 
idefloppy_setup() and idefloppy_open() call idefloppy_capacity which in 
turn outputs the message. So either the printk() should be removed or the 
logic should be changed somehow assuming that there is some case where the 
output makes sense.

Good idea, works nicely. I will suggest this modification to the gentoo 
maintainers.


Best regards,
