Low level disk i/o in C++ for editing the metafiles
Posted on 2004-08-22
I currently own two Maxtor hard drives--both of which I've experienced at one time or another a failure or corruption of the master file table (\$MFT). As a result of this I frequently have backed up the drives metafiles using R-Studio NTFS, but have no way to restore the backed up files without typing in each byte from the backed up file. Frustrated by this, I decided to design a C++ program that would both read and write these metafiles, however I do not know how to do low-level disk I/O in C++ under Windows 2000. Can anyone point me in the right direction to how I might do low-level disk reads and writes in a Windows 2000 C++ environment so that I can save and restore my drives metafiles?
Thanks,
Chris

I guess Windows2000 won't allow you to write directly to any sector of your disk. So the unique solution I know is to build a driver to access IDE I/O port, just like in DOS.
Look at this question related to writting directly to system I/O ports.
