Hi,
Could anyone tell how the CD ripping happens. When I insert a factory burnt
CD and when the player starts ripping there is no IRP_MJ_READ on the CD but
there is some device IOCTL being generated.
Any infromation is helpful.
Thanks,
Kedar.
Maybe you have answered your question
- there are some IOCTLS generated
You may try to test the rip process with the FileSpy
GUI tool (Get the beta from http://www.zezula.net/download/filespy.zip),
it is able to watch IOCTLS and if they
are known (read : documented in DDK headers),
it will show you their constants instead of numbers.
Maybe you will then know more.

Most of the times you’ll see IRP_MJ_DEVICE_CONTROL +
IOCTL_SCSI_PASS_THROUGH[_DIRECT].

Hello Kedar,
Typically the host will use read commands from MMC spec (various format),
encapsulated in SPTI or using (soon obsolete) WNASPI. It does not use the
file system to read.
If you intend to block CD ripping, avoid to block regular applications using
SPTI and/or WNASPI - thanks!
Best regards,

Hi,

there is some device IOCTL being generated.
Any infromation is helpful.
Thanks,

Exactly. MJ_READ is mapped to SCSIOP_READ by CdRom.sys, which reads 2048
byte sectors.
Rippers read the 2352 byte sectors by using the SPTI interface and cooking
all necessary SCSI commands in user mode to do this.

You can also read 2352 byte sectors using the CD-ROM IOCTL. READ_RAW; no
need for SPTI
