Hi,
I have been experimenting a bit about Boot loaders in general for a while now. Found a piece of code, which when loaded onto first sector of first track etc, recognizes the hard drive as a bootable drive and prints message etc.
In the frenzy of testing this code, I used my 8GB pen drive, which had lot of valuable data on it and updated so called MBR ( Master Boot Record ). Needless to say that the experiment failed.
I had a pen drive with data on it, but just MBR overwritten with junk bytes on it. The Windows would recognize the drive, but said, it needs to be formatted. Linux sensed the pen drive connected, but would not mount the media as it did not find correct information in the MBR.
I was determined to NOT to format the pen drive and loose all the data on it. Tried lot many tricks, but they didn't work.
Finally, came across this wonderful free tool at http://www.cgsecurity.org/wiki/Advanced_FAT_Repair, which did the trick.
The tool is simple and easy to use and did precisely what needed it to do. It restored my MBR with default and I managed to see ALL my data intact on the pen drive.
Now, it has made me think more about bit and byte of format process. Will pen down my Boot Loader experiment once I see some ray of hope.
Till then, take care.
