If the local language is not yet supported, english text will be used.

Typically this is only the case for drives which can also write two layered media.</li> </ul> <b>DVD-RW, DVD+RW</b><p> <ul> <li>Some drives report wrong <a href="qa20.php#rw">image sizes</a>.<br> Remedy: Determine the image size from the ISO/UDF file system or the ECC/RS02 data. </li></ul> <b>DVD-RAM</b><p> <ul> <li>Usable only when written with ISO/UDF images like DVD-R/-RW;</li> <li>Not supported when used as removeable medium / for packet writing.</li> <li>Similar issues with <a href="qa20.php#rw">image size</a> recognition as noted above.</li> </ul> <b>BD-R, BD-RW</b><p> <ul> <li>No limitations are known so far, but very few results on the two-layered type (the 50GB variety) have been reported yet. </li> </ul> <b>Not usable types</b> (image can not be extracted):<p> BD-ROM (pressed BDs), DVD-ROM (pressed DVDs), CD-Audio and CD-Video. <div align=right><a href="#top">↑</a></div><p> <b><a name="filesystem">2.3 Which file systems are supported?</a></b><p> dvdisaster works exclusively on the image level which is accessed sector-wise. That means it does not matter with which file system the medium has been formatted.<p> Since dvdisaster neither knows nor uses the file system structure, it can not repair logical errors at the file system level. It can not recover lost or deleted files. <div align=right><a href="#top">↑</a></div><p> <b><a name="aspi">2.4 What does "SPTI" and "ASPI" mean?</a></b><p> Windows 98 and ME use drivers called "ASPI" to access CD/DVD drives. Windows NT and its successors provide similar functionality through an interface named "SPTI", but do still allow the installation of additional ASPI drivers.<p> <i>> Pro and Con of installing ASPI under Windows NT/2000/XP:</i><p> <table> <tr valign=top><td>+</td><td>No administrator priviledges needed for accessing the drives.</td></tr> <tr valign=top><td>-</td><td>ASPI does not map well onto the Windows drive letters.</td></tr> <tr valign=top><td>-</td><td>Some CD/DVD writing programs install their own ASPI drivers. Installing another ASPI driver may interfere with the existing software.</td></tr> </table><p> <i>> Which ASPI versions are recommended for use with dvdisaster?</i><p> Adaptec provides their ASPI drivers free of charge for download. Sometimes versions 4.72.* have difficulties recognizing drives under Windows 2000/XP. Downgrading to version 4.60 usually helps in such cases.<p> <i>> Drive letters are wrong under ASPI!</i><p> ASPI drivers use their own system of identifying drives, which does not support the drive letter scheme of Windows.<br> In order to provide a unified access to SPTI and ASPI, dvdisaster tries to guess the mapping of ASPI drives to drive letters. However this does not work under all configurations.<p> The --list function prints out the current mapping of drive letters.<p> <i>> How to select between SPTI and ASPI?</i><p> dvdisaster will automatically choose between SPTI and ASPI, deciding in favor of SPTI if both are available. Usage of ASPI can be forced; see the description of the --list function for details. <div align=right><a href="#top">↑</a></div><p> <!--- do not change below ---> <?php # end_page() adds the footer line and closes the HTML properly. end_page(); ?>
