Program to test hard drives

[Elena]

Hi,

I tried posting this question to the C++ forum, but this one looks like it gets a little more activity, so hopefully someone here can help.

I am new to C++, trying to teach myself, so this may be easier than I think. I am looking into writing a program in C++ to test basic functions on an ATA hard drive, such as read, write, identify, etc. Does anyone have any information on where I can learn more about it?

Thanks,

Elena

Such low level access is privileged (you need to be root/admin) and very specific to your operating system.

This will be a DOS based program. My company deals alot with hard drives, so we do a lot of testing. The manufacturer's test tools leave a lot to be desired, so I want to make one of our own. What I mostly need help with is learning about PCI and UDMA, how to access through the PC interrupts, etc. I already know how to do simple PIO commands.

Any info on where I can learn more would be helpful.

Thanks,
Elena
