raw sector reading from an ext3-formatted USB disk on Windows XP

Hi everyone.

I read sectors from an ext3-formatted USB disk consisting of just one partition by using Disk Probe on Windows XP.
I watched contents of from the 1024th offset (starting from 0th sector), i.e. 2nd sector.
Although it must be a super block, all value of that sector (2nd one) is zero.
Furthermore, I wrote a raw-sector reading program and read from, but all is zero too.

Is there anything that I misunderstand?
Please give me your opinion.

Thank you.

Not sure if this is correct because I never did an indepth study of it but ext3 is the same as ext2 filesystem but has a parity type feature. Ext3 is a journaling filesystem. Where ext2 is not. This might be what you are seeing.
