Read from a SD card

an SD card should be no different than reading from any other drive.  you just have to know thedrive letter,.

Hi wellio, can you give me a sample in vb.net. Thanks a lot.

To elaborate on my question, I have raw data saved in the SD card in a different file format since even when I access the SD card from using windows, I don't see any thing. I use dd.exe to extract the information saved and convert it into .dat file. Then I use Ultraedit to view the information. The problem is, the data comes out all scrambled in ultraedit. I just want to have my own application wherein I can directly read from this SD card with the data in a well defined manner. Thanks.

what type of data is it?
just like any data it was designed to be opend in a specific format. since it is in an SD card can iassume it is images? is it ascii? ansi? some random binary?

depending on how you need to read the data will determine the method in which you read it using vb.net.

here are some examples

Yes it is random binary.

The data originally comes from a hand reader device directed to a printer port, but instead of printing, we saved the information to an SD card. And we are just trying to retrieve that raw data using our own application in vb.net. The garbled message is because there are lots of empty sectors in between the actual data after using dd.exe. I don't know how to get rid of them?

Forced accept.
