如何从中读取扇区并以编程方式禁用CD-ROM缓存？ [英] How to read sectors from medium and disable CD-ROM caching programmatically?

问题描述

出于某些目的，我希望CD-ROM驱动器始终从介质（光盘）读取扇区，而不是从缓存（易失性或非易失性）中检索它们。我知道我应该使用缓存模式页面（08h）。

发送其他SCSI命令，如28h（READ CD）或BBh（SET CD SPEED）很简单但我不知道如何发送模式选择缓存模式页面选项或结构，我不确切知道。



我搜索了这么多，但一无所获。所以请给我一个详细的C ++代码来禁用CD-ROM缓存或一些代码从中读取扇区。



谢谢

解决方案

For some purposes I want CD-ROM drive always read sectors from medium (disc) not retrieve them from cache (volatile or non-volatile). I know I should use Caching Mode Page (08h).
Sending other SCSI command such as 28h (READ CD) or BBh (SET CD SPEED) was fine and easy but I have no idea how to send Mode Select with caching mode page option or structure, I don't know exactly.

I've searched this so much but found nothing. So please give me a detailed C++ code to disable CD-ROM caching or some code to read sectors from medium.

Thanks
