Does anyone know how to re-write the control data block on a DVD-RAM disk? I ask because it appears that this contains information that has become so as to make the disk unformattable, unreadable. On this particular disk, blanking was successful on one side but still can't be formatted. I wasn't so lucky with the other side! The output of dvd+rw-mediainfo is: INQUIRY: [HP ][DVD Writer 940d ][3H23] GET [CURRENT] CONFIGURATION: Mounted Media: 12h, DVD-RAM Current Write Speed: 3.0x1385=4155KB/s Write Speed #0: 3.0x1385=4155KB/s Write Speed #1: 2.0x1385=2770KB/s GET [CURRENT] PERFORMANCE: Write Performance: 3.0x1385=4155KB/s@[0 -> 0] Speed Descriptor#0: 00/0 R@xxxxxxxx=6925KB/s W@xxxxxxxx=4155KB/s Speed Descriptor#1: 00/0 R@xxxxxxxx=6925KB/s W@xxxxxxxx=2770KB/s READ DVD STRUCTURE[#0h]: Media Book Type: 00h, DVD-ROM book [revision 0] Legacy lead-out at: 2314080*2KB=4739235840 DVD-RAM SPARE AREA INFORMATION: Primary SA: 0/12800=0.0% free Supplementary SA: 0/0=nan% free DVD-RAM WRITE PROTECTION STATUS: Persistent Write Protection is off READ DISC INFORMATION: Disc status: other Number of Sessions: 1 State of Last Session: complete "Next" Track: 1 Number of Tracks: 1 READ FORMAT CAPACITIES: unformatted: 0*2048=0 00h(800): 2236704*2048=4580769792 00h(800): 2295072*2048=4700307456 READ CAPACITY: 0*2048=0 I think it is the read format capacities and spare area information that need to be modified. I can't guess if disc status does.
