Just read the article, thanks!!

I'm using ReiserFS on my Ubuntu partitions, however, following the
recommendation in the wikipedia article, it seems it uses 'ordered data
mode', which would suggest that safe wiping is possible:

[17179578.396000] ReiserFS: hda7: using ordered data mode
[17179608.024000] ReiserFS: hda8: using ordered data mode

Though the article doesn't mention ReiserFS specifically, just ext3.

Thanks for all the links and background info!!

Cheers,
Chanchao
