    Code:
    function DiskInDrive(Drive: Char): Boolean; 
    var 
    ErrorMode: word; 
    begin 
    { make it upper case } 
    if Drive in ['a'..'z'] then Dec(Drive, $20); 
    { make sure it's a letter } 
    if not (Drive in ['A'..'Z']) then 
    raise EConvertError.Create('Not a valid drive ID'); 
    { turn off critical errors } 
    ErrorMode := SetErrorMode(SEM_FailCriticalErrors); 
    try 
    { drive 1 = a, 2 = b, 3 = c, etc. } 
    if DiskSize(Ord(Drive) - $40) = -1 then 
    Result := False 
    else 
    Result := True; 
    finally 
    { restore old error mode }
