CDRoller - Software for CD/DVD/BD/HD-DVD data recovery

CD (DVD, BD) analysis tool and tester.

After a new CD (DVD or BD) is inserted into the drive, the program examines the disc automatically and determines the following:
  • Disc type (Data, Audio, Mixed, DVD or Blu-ray),
  • File System (ISO/Joliet/UDF/FAT32) placed on the disc by CD/DVD/BD mastering software or standalone device,
  • Lost tracks (sessions) that are invisible for Windows "standard" tools,
  • The number of sessions written on the disc and what information each session contains (size, creation date, what program created the session, publisher information and many other details),
  • The number of audio tracks written on Audio or Mixed CD and the size of each track (in bytes and MSF format).

Further, CDRoller scans images have been created before, in order to find the image that is the "mirror" of inserted disc, and then builds own "directories tree" with short cuts to each folder on the disc. In addition, CD/DVD/BD drive is also examined, in order to get its properties and capabilities.

Disc Properties

To display a long files names on the disc originally created under UNIX OS (ISO disc with so-called RockRidge extensions), we recommend to select Dont use path table and check the Ignore Joliet file system... under ISO Reader tab in the Preferences dialog.

For Data Recovery on ISO discs with RockRidge extensions

If you need to check whether your disc is damaged or not and also get advanced Volume Info - you should only run the disc test. The tester reads the system area, it can also determine whether each folder and file is readable or not, and finally, the tester may scan disc surface partly or entirely, reading the blocks of sectors on your CD, DVD or BD. For audio and mixed discs the Digital Audio Extraction Quality measures how well audio tracks can be extracted. To select an appropriate mode, you should only change the options available in the Preferences dialog.

We recommend you to run the Test Disc periodically on the discs with UDF/ISO/Joliet file system in order to make sure a valuable files were really ("physically") placed on the disc, particularly in the following situations:
  • if your DVD was created by Nero Burning ROM (Nero Express).
  • if your CD with photos was burnt from memory cards.
