Not too long ago my last SCSI CD-ROM drive failed. I still have a number of Kurzweil CDROM discs with useful sample libraries on them that I’ve been unable to read as a result – they were made prior to the 3.61 update that added ISO-9660 support.

Marc Halbruegge wrote a fantastic program, KCDRead.exe, that lets you read these older CDROMs and dump the files to a folder on a Win 95/NT/2000 machine. Sadly it didn’t work on XP or newer 32- or 64-bit Windows releases…until now.

In newer Windows, there is a SCSI PassThrough Interface (SPTI) that replaces the old ASPI interface. Someone wrote an ASPI-to-SPTI converter called FrogASPI that runs in usermode and requires no kernel module or driver.

To make this work with kcdread.exe:

0) Download KCDRead from http://www.marc-halbruegge.de/kcdread/kcdread.htm .

1) Download FrogASPI from http://www.softpedia.com/get/CD-DVD-Tools/CD-DVD-Rip-Other-Tools/FrogAspi.shtml .

2) Extract the frogaspi.dll file. Rename it to wnaspi32.dll and copy it to the same directory as kcdread.exe.

3) Run kcdread.exe. It will be able to directly read Kurzweil CDROMs in your physical CDROM drive.

Thanks to Marc again for creating such a useful program!
