Opening CDRoller.

Q: After i have inserted a disc into the drive, the program seems to hang my system. Any suggestions?
A: 1. If you recover CD data, try to turn off DVD reader and use the CD recovery methods only:
- Remove the disk(s) from the drive(s) and start CDRoller again (without any disks inserted).
- Click the Preferences from the View menu. Uncheck the Apply DVD Reader box under the UDF reader tab in the Preferences dialog.Click the OK button to close the Preferences.
- Insert the disc again.

2. If you have installed a software from Fengtao Software Inc (DVD Region, DVD Idle, etc.) before, we recommend to UNCHECK Always read Full TOC box under the UDF Reader tab.

3. Perhaps, your drive can not support some special methods to recognize unreadable disk. Please try the following way:
- Remove the disk(s) from the drive(s) and start CDRoller again (without any disks inserted).
- Click the Preferences from the View menu. Uncheck Always use a drive capabilities and Detect disc insertion by Windows boxes under the Browser tab in the Preferences dialog. Click the OK button to close the Preferences.
- Insert your CD (DVD) into the drive and wait for the end of CD or DVD reading processed by another CD/DVD related program after the disc insertion.
- Click the Refresh button in the Tool Bar.

CD/DVD data recovery.

Q: I have just purchased CDRoller, and though i have identified the missing files, i cannot do anything with them, i.e open and copy to a HDD. Are there instructions?
A: First, please make sure you have registered CDRoller with the help of your license key. If yes, have you closed the program after that? If not, please close CDRoller and start it again without any disk(s) inserted into the drive(s). Then, please select Help/About option and look at the 'About' dialog. Do you see the '(Registered)' near the version number? If the problem still exists, please consult our Support Dept. at support@cdroller.com

Q: I have copied back up files to a CDR in several stages, but the last time I backed up, I was only able to see the most recent batch of files. The others seem to have disappeared... I presume they are still there on the CD but "hidden" in some way - may be a different volume ?
Q: I am trying to recover some data from a CD. Using CDRoller, I can now at least see (and access) some of the files on it. However, it seems like many files are still missing. However, I ran the “Test CD Media” and can see that there are several tracks with varying amounts of data on each of them. Is there a way to access each of these tracks independently to recover my data?
A: Please try Session Selector built in CDRoller. Your CD seems to contain more than one session. In CDRoller 5, in order to select a new session, you should right click on CD name in the List Window and use 'Session' command from pop-up (context) menu. You can also select a disc first and then use 'Session' command from File menu. Beginning on CDRoller 6.0, a list of available sessions is simply displayed in the main program window. Just click a new item with 'Disc Session' type to select a new session. By default, CDRoller manages CD/DVD contents (folders, files) from the last session. Using Session Selector, you can access to the data of all sessions recorded on CD or DVD.

Q: I burnt my DVD in several stages with Roxio Easy Creator Classic 6. However, only the files from the first backup (session) seems to be shown. Why? How i can see the files from the second, third, ... backup (session)?
A: If you have not changed the default settings in the Project Properties, Easy Creator Classic (EZ Classic) writes the both UDF and ISO (Joliet) file systems on the DVD discs. Unfortunately, probably due to the bug, EZ Classic hides a new files in UDF folders, but always shows them in ISO/Joliet ones. A solution is the following:
- Run CDRoller without any discs inserted.
- Click the Preferences from the View menu and check on Read only ISO 9660 tracks box on the Browser tab in the Preferences dialog. Click the OK button to close the Preferences.
- Insert the DVD into the drive and click the Refresh button in the Tool Bar. Only ISO/Joliet files and folders will be shown.
- If the disc contains a several sessions, use the built-in Session Selector.

Q: I am trying to double click on CD/DVD name in the List Window, but i get the message about "corrupted root folder". Is there any chance to read the disc data?
A: 1. The root folder on your disc seems to be unreadable (corrupted). At first, please try Session Selector in order to retrieve the data from previous session(s).

2. If your troubled UDF disc is write-once media (CD-R/DVD-R/DVD+R), try Search All VATs option in order to find and retrieve the files from the previous "backups". Often, this is useful if your CD-R/DVD-R/DVD+R disc was created and unfinalized by Adaptec (Roxio) DirectCD (Drag-To-Disc) software. To find and recover the lost files on all UDF discs, we recommend you to use Scan UDF Disc option from the Tools menu. Note. In case of multisession UDF disc, Scan UDF Disc searches for the files data in all sessions, excluding the current one, therefore some found files may be duplicated with the files retrieved by Session Selector.

3. If your CD/DVD is recorded in ISO file system, try to use the different settings under the ISO Reader tab in the Preferences dialog, and/or Identify Raw ISO Data option from the Tools menu. Note. You should always click the Refresh button before a new settings will take effect. Finally, please feel free to contact our Support Dept. to receive a technical assistance shortly.

Q: I have detected that CDRoller is not able to recognise (identify) my UDF disk inserted into CD-ROM drive (cd reader). However, if i insert the disk into CD-RW drive (cd writer), all files seem to be visible and i can also run Scan UDF Disc to look for the deleted (lost) files. Why?
A: Since UDF disks are written with so-called "packet-written" technology, some old CD-ROM drives can not recognise them at all. Also, if your CD is damaged, incorrectly closed or very poorly written you may also run into the problem that some readers can access to more CD/DVD data than others. In case of big problem, please try a few CD / DVD drives, ask your friends and/or colleagues to run CDRoller on their drives. You often have more success in cd data recovery, if you use CD(DVD)-RW recorders ("cd or dvd writers") instead of CD(DVD)-ROM drives ("cd or dvd readers").

Reading mini DVDs created by DVD camcorders.

Q: I have a Hitachi dvd video camera. It was filming on a dvd-r disk, and about half way through the disk I turned on the camera and got an error message. The disk wasn't finalized, as it was only half filled. Can CDRoller help to retrieve the video files?
Q: I was finalizing a DVD-R in my Hitachi DVD camcorder and received a disc error that was probably the result of a power interruption. What are my chances of recovering any of the material with CDRoller?
Q: I often get probs with the dvd-r disks I use in a sony camcorder dcr-dvd91, usually before finalising. Can your software recover data from these?
A: In order to find and retrieve the lost video and photos, we recommend to use Recover DVD Video option. Just follow the displayed instructions "step by step". To convert the recovered VOB or VRO files into MPEG ones, you can use Split Video option. Finally, just click the Burn button and make a new DVD-video disc that can be played back in the most DVD players.

Retrieving the photos from mini discs created by Sony Mavica CD cameras.

Q: I have tried using the software to open a mini Cd that I took picture on with my Sony Mavica CD camera. Do you have any suggestions on how I can open and save the pictures on the CD?
Q: I have a Mavica photo disk that is damaged, it contains very important pictures, and I'm DEVASTATED! Please give me a few simple hints on how to get started.
A: In order to read the troubled and/or non-finalized Sony Mavica discs, we highly recommend you to use CD (DVD)-RW drive ("cd or dvd writer") - old CD/DVD-ROM drives ("cd/dvd readers") may not access to the lost data. Please follow the instructions from the Chapter 6.8 in User's Manual or Help File, trying Sony Mavica(O) and Sony Mavica CD from the forced scan list.

Recovering video data off the discs created by DVD recorders (standalone devices)

Q: I'm using a standalone Thomson RCA DVD Recorder. I was backing up 2 home movies to DVD+RW when the power went off. How can i get the movies back that (obviously) didn’t get finalized during the recording?
Q: I recorded 3 DVD+R discs one after another, where the first was OK, but the other 2 were bad after recording. I am not sure, what the reason for the problem was, but I think, the device may have problems with overheating. Do you see a chance to recover these two recordings? The device is LiteOn LVW-5001.
A: CDRoller is able to recover the video data (VOB or VRO files) from the discs created by standalone DVD recorders. In order to find and retrieve the lost video, we recommend to use Recover DVD Video option. Just follow the displayed instructions "step by step". To convert the recovered VOB or VRO files into MPEG ones, you can use Split Video option. Finally, just click the Burn button and make a new DVD-video disc that can be played back in the most DVD players.

General questions.

Q: Why do you use temporary storage on HDD to perform different operations such as: Folders and Files Copying, Files Execution, etc.?
A: Using temporary storage and temporary files on HDD to perform commands as mentioned above is one of our methods to manage CD/DVD contents safely and with maximum reliability. Since damaged areas can occur on CD/DVD media, the attempts of direct copying, opening or executing CD/DVD objects may result in loss of data already exists on HDD or even to stop the program responding. To prevent these problems all operations mentioned above and also Digital Audio Extraction are implemented utilizing temporary storage and (or) temporary files on HDD.

Q: Size of my CD is 424 MBytes, it contains 177 folders and 1840 files. I've found size of created CD image is about 32 kBytes. Why?
A: CDRoller creates Short CD/DVD Image as a file that contains ALL DIRECTORY STRUCTURE (directory tree) of your CD or DVD including complete folders and files names with attributes. This enables you to browse through the folders, search for the files or/and folders which you need (with the help of 'Find' option), detect the prorerties of them using 'Properties' command, but in order to retrieve any file, you should insert a "real" CD(DVD). When you insert a disc that has the image that has been created before, CDRoller determines this image as a "mirror" of the real CD or DVD, displays it with an appropriate icon in the List window and further, utilizes image to access to any folder quickly without reading the directory structure on the disk really inserted. This is an extremely useful if your "real" CD (DVD) has become a disc with unreadable folder(s) and, therefore you can not access to its files.

Q: I've found the text file, which was necessary in my collection of CD images. How can I open it ?
A: At first you should be sure that "Open command" option is checked on the CD/DVD Library tab in the Preferences dialog, then you can simply double click on file's name or on it's icon. Further, you'll be prompted to insert a REAL DISC if your CD/DVD drive has no it inside.

Q: I have already created a collection of MP3 encoders on my HDD including different versions of Lame and Blade encoders (DLLs). How can I select appropriate encoder in the CDRoller shell quickly?
A: Just activate the options dialog box on the Audio Extraction tab in the Preferences for assigned encoder (Lame or Blade) and select appropriate DLL from your collection without program restart.

Q: What versions of Lame and Blade encoders (DLLs) did you utilize when testing the program?
A: CDRoller was tested with Lame's versions 3.66 and 3.81, and Blade's version 0.82.

Q: Can I make a suggestion for a new feature?
A: Sure, new suggestions are always welcome, you can send them to suggest@cdroller.com. All the suggestions will be considered at least and you will probably see them as new program's features in the future releases.
