26 /* FUNCTION
27 Write raw data to the partition.
29 INPUTS
30 Partition - a handle to a partition to read from
31 Buffer - a pointer to a data buffer
32 DataSize - Size of data to read in bytes. This size must be a
33 multiple of block size in order to ensure correct
34 operation.
35 StartBlock - Number of the first block to start writing from.
37 RESULT
38 Return code of DoIO() function which was used to write the data.
