Hello,
Is anyone here sucessfully using some external DVD-Ram capable writer?
I've got a external (USB/Firewire) LG GSA-5163D, which is a multiformat
device. ?R(W) seems to work fine so far. But when I insert a -Ram medium
the kernel or devd or whoever is responsible for that doesn't create the
a- and c-partition device nodes. The only exception is when I insert the
medium before hooking the dvd-writer into my notebook.
It doesn't matter whether I use firewire or usb2.
Here's some dmesg output:
Hooking it into firewire, with inserted dvd-ram medium
fwohci0: BUS reset
fwohci0: node_id=0xc800ffc1, gen=2, CYCLEMASTER mode
firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 (me)
firewire0: bus manager 1 (me)
firewire0: New S400 device ID:0050770500000093
cd1 at sbp0 bus 0 target 0 lun 0
cd1: <HL-DT-ST DVDRAM GSA-5163D A102> Removable CD-ROM SCSI-0 device
cd1: 50.000MB/s transfers
cd1: cd present [2236704 x 2048 byte records]
unplugging it again:
fwohci0: BUS reset
fwohci0: node_id=0xc800ffc0, gen=3, CYCLEMASTER mode
firewire0: 1 nodes, maxhop <= 0, cable IRM = 0 (me)
firewire0: bus manager 0 (me)
The /dev/cd1* doesn't go away. When I reconnect it it stays dead until I
reboot the computer. Is Firewire incapable of hotplugging? camcontrol
rescan and fwcontrol -r don't bring it back to life.
connecting it via usb2 without a medium:
umass0: HL-DT-ST DVDRAM GSA-5163D Super Multi DVD Rewriter, rev 2.00/0.01, addr
2
cd2 at umass-sim0 bus 0 target 0 lun 0
cd2: <HL-DT-ST DVDRAM GSA-5163D A102> Removable CD-ROM SCSI-0 device
cd2: 40.000MB/s transfers
cd2: Attempt to query device size failed: NOT READY, Medium not present
I can however readout the disklabel of the medium but I haven't yet figured
out how to mount it then.
Thanks,
Michael
