Hi, I have built up a new computer and the DVD RW doesn't recognize DVDs. I have tried it with a commercially written DVD, and with a blank DVD +RW. The player spins and tries to recognize the DVD without success until it times out and stops spinning. The other player on this computer is a Blu-Ray RW player that I salvaged from a computer my neighbor threw out in the trash. When I put a commercially written DVD or a blank DVD in the Blu-ray player it is recognized, and a written disc is recognized as the source disc in K3b. But no disc is ever recognized in the DVD RW player as the destination. Here's some info to begin with as I tried to troubleshoot this: # dmesg | grep -E -i --color 'cdrom|dvd|cd/rw|writer' [ 1.846359] [ T732] ata5.00: ATAPI: TSSTcorp CDDVDW SH-S223L, SB02, max UDMA/100 [ 1.848860] [ T187] scsi 4:0:0:0: CD-ROM TSSTcorp CDDVDW SH-S223L SB02 PQ: 0 ANSI: 5 [ 2.152487] [ T584] sr 4:0:0:0: [sr0] scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray [ 2.152489] [ T584] cdrom: Uniform CD-ROM driver Revision: 3.20 [ 2.324886] [ T584] sr 5:0:0:0: [sr1] scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray # more /proc/sys/dev/cdrom/info CD-ROM information, Id: cdrom.c 3.20 2003/12/17 drive name: sr1 sr0 drive speed: 48 48 drive # of slots: 1 1 Can close tray: 1 1 Can open tray: 1 1 Can lock tray: 1 1 Can change speed: 1 1 Can select disk: 0 0 Can read multisession: 1 1 Can read MCN: 1 1 Reports media changed: 1 1 Can play audio: 1 1 Can write CD-R: 1 1 Can write CD-RW: 1 1 Can read DVD: 1 1 Can write DVD-R: 1 1 Can write DVD-RAM: 1 1 Can read MRW: 0 1 Can write MRW: 0 1 Can write RAM: 1 1 I pared this to just the players # lsblk sr0 11:0 1 1024M 0 rom sr1 11:1 1 2.2G 0 rom I know only enough to check and see if the player is recognized by the system (Tumbleweed), I'll need some help to go farther.
