[gentoo-user] Unusual DVD-RW behavior?

[gentoo-user] Unusual DVD-RW behavior?

[Jeff]

Hey all.

I'm curious as to why a handful of /dev/ entries seem to be pointing to
the same device - notably, to hdc, which is my DVD burner. See here:

lrwxrwxrwx  1 root root           3 Feb 18 05:29 cdrom -> hdc
lrwxrwxrwx  1 root root           3 Feb 18 05:29 cdrw -> hdc
lrwxrwxrwx  1 root root           3 Feb 18 05:29 dvd -> hdc
lrwxrwxrwx  1 root root           3 Feb 18 05:29 dvdrw -> hdc
brw-rw----  1 root cdrom    22,   0 Feb 15 12:55 hdc

And here is the dmesg spam:

hdc: tray open
end_request: I/O error, dev hdc, sector 0
hdc: tray open
end_request: I/O error, dev hdc, sector 4
hdc: tray open
end_request: I/O error, dev hdc, sector 0
hdc: tray open
end_request: I/O error, dev hdc, sector 4
hdc: tray open
end_request: I/O error, dev hdc, sector 8
hdc: tray open
end_request: I/O error, dev hdc, sector 12
hdc: tray open
end_request: I/O error, dev hdc, sector 16
hdc: tray open
end_request: I/O error, dev hdc, sector 20
hdc: tray open
end_request: I/O error, dev hdc, sector 24
hdc: tray open
end_request: I/O error, dev hdc, sector 28
hdc: tray open
end_request: I/O error, dev hdc, sector 32
hdc: tray open
end_request: I/O error, dev hdc, sector 36
hdc: tray open
end_request: I/O error, dev hdc, sector 40
hdc: tray open
end_request: I/O error, dev hdc, sector 44
hdc: tray open
end_request: I/O error, dev hdc, sector 48
hdc: tray open
end_request: I/O error, dev hdc, sector 52
hdc: tray open
end_request: I/O error, dev hdc, sector 56
hdc: tray open
end_request: I/O error, dev hdc, sector 60
hdc: tray open
end_request: I/O error, dev hdc, sector 0
hdc: tray open
end_request: I/O error, dev hdc, sector 4
cdrom: open failed.

Is there some sort of conflict over devices here? I've never seen this
type of idle activity before. How can I get the /dev/ directory and/or
my system to only recognize one /dev/ entry as my DVD-RW, ala hdc?

Thanks!

It is probably fine as various programs look for different device names.
Since you'd play music CDs as well as write DVDs in that one device
only,  links shall help those application find your current media.

are you trying to eject here and that fails? Or a boot? What are you
trying to do?
If it was my drive, and I was sure it was not dying on me - I would
probably not bother at all - unless it was unable to play music or write
media.
HTH,

Nothing fails.  Well, if you can call it a failure all that it fails is that
there is no CD/DVD in the device.  The messages 'hdc: tray open' tell you
that the tray is open.  The message 'cdrom: open failed.' tells you that
there is no disk in the device to be opened (i.e. CD/DVD).  If you reboot
with a CD/DVD in it there shouldn't be an 'open failed' message.
