7.5. Examining disc sectors at low level

Top  Previous  Next


Key features.


· Intensive disc scan for particular data. For example, it searches for an email address on a disc regardless of what file the mail may be in. Can be used to examine the data on optical discs (CD, DVD, Blu-ray) and also on hard disks, flash drives and other types of Windows disks/drives. To activate the search window, just click the Examine Sectors button in Other Tools section of Side Bar, or select the same command in the Tools menu.




You can stop a search in any time, view intermediate results and continue the process where you left it before.


· Sector View allows you to display the disc sectors in the Text, Binary, Hexadecimal/Text or Unicode mode. There is no requirement that the sectors belong to a file - any sector on the disc can be displayed. Just click View sector button in the Examine Disc Sectors dialog shown above. There is no limitation to view the sector data only in a single window - multiple Sector View dialogs can be open at the same time.




To move between sectors you can either use the arrows to the right of the sector number, or you can enter a sector number and press the Enter key, or just paste a new sector number from the clipboard. You can simply adjust the font size under the View tab in order to get more comfortable view. Copy and Save To File options are also available under the Export tab.


· The Copy sectors tab allows the direct copying of selected sectors to a disk file. Unchecking Replace bad sectors with zeros: is useful for certain types of discs, such as DVD camcorder mini discs. CDRoller will normally replace unreadable sectors with binary zeros to maintain the relative positions of data. This can cause problems for video players so when copying movie data this option should be unchecked.




· Direct examination of the content of selected file from the main window. To view file content,  just select a file in the main window and click the Examine Sectors button in Other Tools section of Side Bar. Or, right click the file name and select Examine Sectors from the pop-up menu.



You can find a particular data (text), using a set of options under the Search tab. The information can be also displayed in the Text, Binary, Hexadecimal/Text or Unicode mode with font size adjustment. The data pane can be also resized and scrolled.


· Support of External Hex Editor. Instead of built-in Sector Viewer, you can simply connect a professional hex editor (WinHex, FlexHex, Hex Workshop, HxD, etc.) and use it for detailed analysis of selected sectors or file data.


To activate this option, just check the Use external hex editor... under CD/DVD Library tab in the Preferences dialog:




The next time, when you apply Examine Sectors to the selected disc or file in the program window, you're asked to assign External Hex Editor, software installed in your system.




Note. If you manage the inserted disc with CDRoller Image, all changes in the sectors data saved by external editor will modify the image file. Further, you can recover files/folders, or extract a whole track(s), or create ISO Image File, and then burn a new disc with modified data without leaving CDRoller.
