Hi, I have written a multisession data DVD+R with Nero Burning ROM 6.3. Then I haven't added any more session and I have closed the disc with Pinnacle Instant CD/DVD 8 OEM. The content of this disc is accessible without any problem under Windows 2000. Under Linux, when I try to mount the disc with 'mount /dev/writer /mnt/writer/', I get this error:
mount: block device /dev/writer is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/writer, or too many mounted file systems I (obviously) obtain the same error when i try to use it in my dvd-rom. The strangest thing is that I can mount (and then access as usual) this disc with 'mount -oloop /dev/writer /mnt/writer' Have you got any idea about this behaviour? Is it possible to make the disc 'normally' (without '-oloop') mountable again? Thanks in advance, Mirco Lorenzoni P.S. 1) I'm not a list subscriber, therefore send me a copy of the reply, please. 2) Here are some informations about my system and the 'strange' DVD+R: Linux kernel version 2.4.27 output of dvd+rw-mediainfo /dev/writer: INQUIRY: [TSSTcorp][CD/DVDW TS-H552B][TS04] GET [CURRENT] CONFIGURATION: Mounted Media: 1Bh, DVD+R Current Write Speed: 4.0x1385=5540KB/s Write Speed #0: 4.0x1385=5540KB/s Write Speed #1: 2.0x1385=2770KB/s Speed Descriptor#0: 00/2295103 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s Speed Descriptor#1: 00/2295103 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s READ DVD STRUCTURE[#0h]: Media Book Type: A1h, DVD+R book [revision 1] Media ID: YUDEN000/T01 Legacy lead-out at: 2295104*2KB=4700372992 READ DISC INFORMATION: Disc status: complete Number of Sessions: 2 State of Last Session: complete Number of Tracks: 2 READ TRACK INFORMATION[#1]: Track State: invisible Track Start Address: 0*2KB Free Blocks: 0*2KB Track Size: 2053344*2KB ROM Compatibility LBA: 265696 READ TRACK INFORMATION[#2]: Track State: invisible Track Start Address: 2055392*2KB Free Blocks: 0*2KB Track Size: 4294967232*2KB ROM Compatibility LBA: 265696 FABRICATED TOC: Track#1 : [EMAIL PROTECTED] Track#2 : [EMAIL PROTECTED] Track#AA : [EMAIL PROTECTED] Multi-session Info: [EMAIL PROTECTED] READ CAPACITY: 2055328*2048=4209311744 output of cdrecord-prodvd -scanbus: Cdrecord-ProDVD-Clone 2.01b31 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling Unlocked features: ProDVD Clone Limited features: This copy of cdrecord is licensed for: private/research/educational_non-commercial_use Linux sg driver version: 3.1.25 Using libscg version 'schily-0.8'. scsibus0: 0,0,0 0) 'TSSTcorp' 'CD/DVDW TS-H552B' 'TS04' Removable CD-ROM 0,1,0 1) 'JLMS ' 'XJ-HD165H ' 'CH12' Removable CD-ROM 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) * 0,7,0 7) * output of cdrecord-prodvd -toc: Cdrecord-ProDVD-Clone 2.01b31 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling Unlocked features: ProDVD Clone Limited features: This copy of cdrecord is licensed for: private/research/educational_non-commercial_use scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.25 Using libscg version 'schily-0.8'.
