Question RAW disk I/O.

[rhoaste]

Hi,

I am attempting to write an application to accompany an electronics project I've been working on. I am capturing data from a device I have built and logging it to an SD card using a micro-controller. The device writes data to the SD card is in RAW format, which does not conform to Microsoft's file system specifications.

I would like use VB.NET to access the SD card's raw sectors without using a file system, so I can interpret the data captured by the micro-controller. After searching about for some time, I have run up against a brick wall.

Any help would be gratefully received.

Kind regards,

Probably need to use P/Invoke for that. Here's a couple of links that should get you started.

pinvoke.net: CreateFile (kernel32)

CreateFile Function (Windows)

No luck at all getting this operational in any capacity. Does anyone have a VB.NET sample of using these functions in conjunction with the RAW disk format?
