January 25, 2000.
Request for ASPI license was denied by Adaptec. CDRoller development team came to the hard decision to delay the first public release and to re-develop the program in order to make it independent on ASPI entirely. For this purpose the development of the proprietary driver started.

December 11, 1999.
Request for an ASPI layer redistribution license sent to Adaptec.

Version 1.00 - December 10, 1999.
The first program version planned to be a public release:
- Explorer-like CD media navigation interface.
- Folders and Files management is provided.
- Data CD images creation and using.
- Extraction and playing audio CD tracks.
- The program operated with pure Data CDs / pure audio CDs only. All operations are implemented assuming ASPI from Adaptec support.

June, 1999.
CDRoller project started.
The purpose of this project is development of multifunctional toolset like well-known Norton Utilities [1], available for beginners and advanced users to manage CD drives and CD media on low- and mid-level. Advanced SCSI Programming Interface (ASPI,[2]) is chosen as low-level CD-ROM access method. Although, the initial version of ASPI manager included in Windows 95/98 releases seems to be instable and partially malfunction, CDRoller development team believed in Adaptec's promises to license ASPI for redistribution.
