[000 Main Menu: Welcome to Disc Detective ]
Disc Detective end user series is a versatile collection of tools which allow you to verify the quality and integrity of data on all your compact discs including multimedia and Video CDs. These tools give you access to every sector of your CD-ROM, and perform complete sector by sector comparisons between discs. This version includes audio player functions.
The professional series of Disc Detective (CDDPRO), has advanced premastering and analysis functions for data and audio CDs. It compares discs to image files resident on hard disk or tape (8mm Exabyte and 4mm DAT). It allows editing of any sector in an image file, so you can fix a problem your analysis may find. Video CD functions are also included.
The Disc Detective Data Verification System  is a combination of the professional series of Disc Detective, with a Pentium 90 computer and a CD-ROM drive tower for comparison of multiple discs. Add a tape drive, and you can compare up to 6 discs to an image file on tape. An exciting new addition to the Disc Detective family of CD verification products.
