Ed Mulroy (TeamB) suggested that I post this request for help here----

I'm trying to read (for now) a CompactFlash Card on a USB2.0 port.  I've attached a file using 
biosdisk from an antique version of TurboC.  On my WinME laptop, all it finds is Drive C (at drive 
== 0x80), even with the CompactFlash Card and reader proper installed.

I'd like to use C++ Builder 6 to do the job - can anyone help with appropriate calls (WinAPI, etc).

Example TurboC 1.0 Code:
{
    int buffer[16384],i,j;
    int cmd, drive, head, track, sector, nsects;
    int status,ndrives;

    drive = 0x80;
    ndrives = 0;
    while (drive !=  0x88)
    {
       cmd = 2;        /* Read Drive - per biosdisk() */
       head = 0;
       track = 0;
       sector = 0;
       nsects = 32;
       status = 1;
       status = biosdisk (cmd, drive, head, track, sector, nsects, buffer);
       printf ("drive = 0x%02x   status = 0x%04x\n",drive,status);
       if( status == 0 ) ndrives++;
       drive++;
    }
}
