Hi,
I''m developing an application for interfacing with pen drive. I got handle and successfully Read & Write into the sectors. I need to Read/Write values in the reserved space of the drive. In the FAT32 Boot Record, there are reserved sectors in the offset 0Eh. Can i read/write in these reserved sector?. If so how can i do it?
Regards

推荐答案
SetFilePointer(hFloppyDisk,offset,0,FILE_BEGIN);
例如，假设我们有一些扇区，每个扇区的大小为512字节，并假设您要访问扇区3.您希望像这样设置文件指针:
For example, let''s assume we have sectors with a size of 512 bytes each and let''s say you''d want to access sector 3. You''d want to set the file pointer like so:
SetFilePointer(hFloppyDisk,3*512,0,FILE_BEGIN);
这篇关于读/写FAT32引导记录的保留扇区的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
