Hardware Access Method (default value is: CDRoller proprietary driver for Windows 9x/ME or Windows NT native access for Windows NT4/2000/XP/2003/Vista/7/8/8.1). Sets one of two methods to access hardware. The key feature of SPTD (SCSI Pass Through Direct) layer is an ability to provide a direct access to your computer drives and avoid a conflict with "malicious" filter drivers that can be installed by 3-rd party software. In other words, if you have another CD/DVD/BD related programs in your system and CDRoller cannot recognize the inserted disc or data recovery seems to be stalled, please select "SPTD interface" and try to read your disc again. Note. We do not distribute SPTD layer with CDRoller. It is available for download at .


Set Exclusive Access (default value Uchecked).

If Checked, only CDRoller will have an access to the hardware (your computer drives) via SPTD layer.


Date Format (default value Short Form)

Sets the Date format used by the program to display the Date information.


Time Format (default value Short Form)

Sets the Time format used by the program to display the Time information.


Treat KByte as: (default value 1024 bytes)

Detects the way of 'kilobyte consideration' as 1024 bytes exactly (in 1024 bytes mode) or as 1000 bytes (in 1000 bytes mode). It may be useful for correct file (folders or audio tracks) size calculation, before these items will be sent to hard disk.


Search of the lost data track (default value Checked)

If Checked , the program searches the lost data track when a new disc is inserted or after Refresh command, and, if found, displays its contents in the List Window.


Detect disc insertion by Windows (default value Checked)

If Checked the program detects arrival or removal of the disc using Windows "standard" tools (messages). This starts disc recognition automatically, without requirement of the refresh. If the program can not recognize your disc automatically, try to uncheck this option and repeat examination of a new disc by clicking the Refresh button in the Tool Bar.


Read damaged sectors "as is" (default value Unchecked)

If Checked , when reading system area and folders, unreadable sectors will be accepted "as-is".  This may be useful in some circumstances, but it should be understood that the content of these "accepted" sectors could be all zero or partially correct data there is no way to tell. You should use this mode only if the program can not "recognize" your damaged disc or you vitally need an access to the unreadable folder. Please keep in mind that your computer drive may not support reading of disk sector "as is" or the content of that sector may be denied by the further checks in compliance with ISO 9660 and UDF requirements.


Read only ISO 9660 data tracks (default value Unchecked)

If Checked, the program searches and verifies only ISO system area on data tracks after insertion of new disc. Discs with another file system, such as UDF, require additional recovery procedures that may take a some time, especially while reading multisession ones. If you are sure that your disc is actually recorded in ISO 9660 format, you should check on this option in order to accelerate the disc recognition. Obviously, to read the discs with UDF file system, this option has to be unchecked


Always use a drive capabilities (default value Checked)

If Checked, when reading the damaged sectors, the program will apply some low-level methods and algorithms based on the capabilities of your computer drive. In some circumstances the drive can slow the process when meeting a bad zones (unreadable sectors). In this case we recommend you to uncheck this option.


Display deleted files and folders (default value Checked)

If Checked, the program displays files and folders having deleted characteristics on UDF disks. The objects are shown with special Inaccessible file icon in the List Window. You can try to recover them with the help of Scan UDF Disc command from Tools Menu.


Apply MRW reader (default value Checked)

If Checked, the program automatically recognizes CD-RW disk formatted in the "Mt.Rainier" CD-RW format (CD-MRW) placed into non-Mt.Rainier drive, and presents the data portion of the disk as a "read only" UDF format disk. We also recommend you use this to read the disk inserted into CD-MRW drive if your MRW disk was not ejected (closed by cd mastering program). For example, if the writing process was interrupted by a system or power failure.

Hint. To check the drive capabilities, use Properties command applied to the "empty" drive in the List window and select Features tab in the Properties dialog.


Display adviser window (default value Checked)

If Checked, a separate panel ("adviser") with some recommendations and results of disc analysis will appear inside the program window.


Apply FAT32 reader (default value Unchecked)

If Checked, the program automatically recognizes the disc, formatted with FAT32 file system.
