当统计软件读取一个以ascii或EBCDIC为格式的原始数据文件时，必须照着顺序一个一个字节地读取。
When statistical software reads a "raw" character format data file consisting of ASCII or EBCDIC characters, it must read each byte in sequence.
因此，这个区域在被新的数据覆盖之前，原始数据都是可以被还原的。 这就是所有数据还原软件的工作原理，根据目录还原那些已经删除的数据文件。
When you delete a file, all you are doing is removing it from the directory and flagging that part of the drive as being available for new data.
