From: fab on 8 Jul 2010 09:40 Hello. I can't blank CDs anymore, using either cdrecord or cdrdao, even though I could do it before. Can a kernel upgrade be a reason? Any other hint? Thanks. -- F. Delente

Any other informational message besides "I can't" ?-) You may even try and add some verbosity to the output (switch '-v') elsewhat maybe that's just somebody opened your box and stole your CDwriter ;-)

May be but is unlikely. Try using the previous kernel and see. > Any other hint? Without more information no. Try blanking a CD-RW using the command "cdrdao blank -v 2" and post the messages here. It may helps us help you. Regards.

My upgrade was a while ago, I compiled the kernel myself, and I didn't keep the older one, so I can't revert to it. > Without more information no.

Ok, here it is, but it's rather terse: $ cdrdao blank -v 2 Cdrdao version 1.2.1 - (C) Andreas Mueller <andreas(a)daneb.de> SCSI interface library - (C) Joerg Schilling Paranoia DAE library - (C) Monty Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables.

Not clues there on the cause! Try a higher verbose level (3 or higher) to see if some clue emerges. cdrdao blank -v 3 Also try the "cdrdao drive-info" to see if the drive's capabilities are correctly detected. > /var/log/messages gives > > Jul 8 16:48:32 slick kernel: usb 3-2: new high speed USB device using > ehci_hcd and address 7 > Jul 8 16:48:32 slick kernel: usb 3-2: New USB device found, > idVendor=04b4, idProduct=6830 > Jul 8 16:48:32 slick kernel: usb 3-2: New USB device strings: Mfr=56, > Product=78, SerialNumber=100 > Jul 8 16:48:32 slick kernel: usb 3-2: Product: USB2.0 Storage Device > Jul 8 16:48:32 slick kernel: usb 3-2: Manufacturer: Cypress Semiconductor > Jul 8 16:48:32 slick kernel: usb 3-2: SerialNumber: 123456789012345 > Jul 8 16:48:32 slick kernel: scsi7 : usb-storage 3-2:1.0 > Jul 8 16:48:33 slick kernel: scsi 7:0:0:0: CD-ROM HL-DT-ST > DVDRAM GSA-T40N JR03 PQ: 0 ANSI: 0 > Jul 8 16:48:33 slick kernel: sr 7:0:0:0: Attached scsi generic sg2 type 5 No clues there either. > I tried both as a user and as root, but I got the same error (I could > do it as a user before anyway). Not a permission problem then. > Thanks for any hint. Regards. |
