The Win32 port of cdrdao is based on the Cygwin Unix environment for Windows. This package comes with the binary version of the cygwin1.dll. You can download the corresponding source code from http://sourceforge.net/projects/cdrdao in the download section or via www.cygwin.com. This port should work on all Win32 operation systems. If you will use "cdrdao.exe" in dos prompt under win9x, (or restart in MS-DOS mode also), you have to check off "Auto Insert Notification" of the CD-R drive property. When you do "cdrdao.exe read-xx" with "Auto Insert Notification" property, your PC will hang (write is O.K.). During writing you should avoid to open the Explorer and similar tools. Currently, cdrdao does not lock the recording device so that all access action from the Explorer will lead to a failure of the recording process. Cdrdao requires a working ASPI installation for operation. You can fetch an ASPI installation package from Adaptec's home page. After a successful ASPI installation the command cdrdao scanbus should list all of your CD-ROM, DVD and recorder devices. If not the following registry changes should make them visible: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Aspi32] "ErrorControl"=dword:00000001 "Type"=dword:00000001 "Start"=dword:00000002 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Aspi32\Parameters] "ExcludeMiniports"="" You can also execute the file "aspi.reg" to make the registry updates automatically. A 'cdrdao scanbus' output looks like this: 1,0,0: E-IDE, CD-ROM 52X/AKH, A6E 1,1,0: ARTEC, WRR-4048, 1.01 The number triple (e.g. 1,0,0) is the address of the drive. It must be used with the --device option of cdrdao to select the recorder or reader device. For example copying a CD works like this: cdrdao copy --source-device 1,0,0 --device 1,1,0 For simple tests you can use test toc-files from the "testtocs" directory: cdrdao simulate --device x,y,z testtocs/t1.toc This will run a write simulation with the layout of a simple audio CD. It is very useful to verify the principal functionality of cdrdao on you system.
