• You need to P/Invoke CreateFile, meet the paragraph about Concrete Disks and Volumes.

• Hello wep1.

  tin you lot describe the requirements in more than detail?

  I would look that any organisation would employ a SD card as a regulard disk and just places a file with raw data on the file system. Simply from what yous wrote it could be understood in a manner, that no filesystem is used at all and the information is directly written on the SD disk.

  Could y'all please clarify this indicate?

  In general, you can accept these solutions:

  1st) This is easy considering you are opening the file and read it. The data must exist taken in the right format (which must be specified of course!).

  2nd) Thius is a lilliputian harder. The cadre solution in hither is to employ P/Invoke and and then telephone call some functions like CreateFile (http://msdn.microsoft.com/en-u.s./library/aa363858.aspx).

  If you lot provide more than data nosotros could signal your further on how to read the file or device.

  With kind regards,

  Konrad
