File system magic numbers
 

Hi,

Can anyone please tell me where to find resources (technical if need be) on File system Magic Numbers and some info on how to decipher the MBR contents?

This might be of help for MBR. http://www.cpqlinux.com/mbr.html
As far as the Magic Number I did a google search and found many links on it. Might check start there.

Check http://www.nondot.org/sabre/os/articles

The MBR uses partition magic numbers. Linux's fdisk(8) understands some of them. Filesystem magic numbers are a different thing.

Thanks, folks, for clearing things up.

Bah, I've googled around for days, but since I'm no geek, it is quite difficult to get to the right pages. :p

EDIT: Hmmm, I'm no geek? Since when does an average home user read papers on MBR? I've gotta further investigate my inner geekness. :)))

For future linux googling use http://www.google.com/linux

Thanks.

Man, I've found some great stuff in the links mentioned in previous posts by primo and Brian1. Thanks a lot, guys!

Here's something for an odd passer-by's viewing pleasure:

1. The Minimal Partition Table Specification:
http://www.win.tue.nl/~aeb/partition...on_tables.html
Great description of what's inside partition tables.

2. Partition Types:
http://www.win.tue.nl/~aeb/partition...ion_types.html
The first section contains a formidable list of various partition types and coresponding "magic numbers".
