在FAT32引导记录中写入保留空间 [英] Writing in Reserved space in FAT32 Boot Record

问题描述

我正在开发一个用于在Windows XP中连接笔式驱动器的应用程序.我的应用程序与笔式驱动器连接并测试了示例读/写扇区.我需要在笔式驱动器中存储一些机密值，任何人都不得更改.在FAT32引导记录结构中，我们在偏移量34h处具有12个字节的保留空间.我在FAT32引导记录的保留空间中写入/读取值，其工作正常.我的问题是，我将在这些空间中书写还是会在任何时间影响任何地方.请澄清我的疑问.

Hi,
I''m developing an application for interfacing Pen drive in Windows XP. My application gets connected with Pen drive and test sample read/write sectors. I need to store some confidential values in the pen drive that should not be change by anybody. In FAT32 Boot Record structure, we have 12 bytes of reserved space at offset 34h. I write/read values in the reserved space of the FAT32 boot record, its working fine. My question is, will i write in these space or will it affect anywhere at anytime. Please clarify my doubt.

推荐答案

好吧，那个12字节的区域被标记为保留"，这意味着将来的操作系统可以随时使用它.您还可能会遇到某些防病毒应用程序，将该区域中的数据视为可能的病毒攻击.

Well, that 12-byte region is marked as "reserved", which mesans a future OS could use it at any time. You may also experience certain Anti-virus apps seeing data in that region as a possible virus attack.
