DVD vazio? como?

DooDlez · 21 de fevereiro de 2009

Seguinte: Meu dvd le todos os dvds, menos esse.

Pensei que o dvd que gravei que estava com problema, mas nao. em um outro PC, rodou perfeitamente.

Tenho um DVD do windows vista e ele esta sendo reconhecido como vazio, mas em outro PC funcionou perfeitamente.

OBS: a imagem dele que esta no PC, quando abri com o rar, tem isso escrito

This disc contains a "UDF" file system and requires an operating system

that supports the ISO-13346 "UDF" file system specification.

Qual a solucao.

OBS: meu PC roda outros DVDs perfeitamente.

E qual é o sistema operacional que você está usando? Quero adverti-lo que se for o Windows XP, só aceitará um CD ou DVD com UDF (Universal Disk Format) se ele estiver com o Service Pack 3 (SP3). Não funcionará com o SP2.

Veja na Wikipedia o que eu encontrei:

Why a computer might not read a particular UDF disk
Even if an operating system claims to be able to read UDF 1.50, it still may only support the plain build and not necessarily either the VAT or Spared build.

An example is Mac OS X (10.4.5), which claims to support UDF 1.50 (see man mount_udf), yet it can only mount disks of the plain build properly (it cannot mount UDF disks with a VAT at all, see Sony Mavica problem, and while it appears to be able to mount CD-RWs written with a Sparing Table, it does not read its files correctly in the case those files are actually remapped).

The solution is to update the computer’s operating system (OS) to any later version of the OS, available without charge up to version 10.4.11 for both Intel and PowerPC Macintosh computers.

Similarly, Microsoft Windows XP Service Pack 2 (SP2), cannot read DVD-RW disks that use the Universal Disk Format (UDF) 2.00 defect management system. When you view the DVD contents by using Windows Explorer, you see an empty root folder. This problem occurs if the UDF defect management system creates a sparing table that spans more than one sector on the DVD-RW disk. Windows XP SP2 cannot read a sparing table that is larger than one sector. Windows XP SP2 can recognize that a DVD is using UDF. However, Windows Explorer displays the contents of a DVD as an empty folder.

One can update the computer to Windows XP Service Pack 3, or to apply a hotfix to address this specific problem.

For solutions to more general problems reading UDF-formatted optical disks in computers using Microsoft Windows OSes, see Microsoft Windows UDF Read Troubleshooting.

[edit] Standalone DVD player compatibility

Some users have reported that video DVDs burned on their computers in UDF version 1.5 are not compatible with their set-top video DVD players. These players seem to be only compatible with UDF version 1.02 (that provides both UDF and ISO 9660 directories.) As some popular DVD burning programs default to UDF version 1.5 when burning video DVDs, users have found it necessary to avoid using the software wizard and instead manually configure the burn to version 1.02.
