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.

Regards
Mohan

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.
