Meh, the only FS I've ever lost data to - aside from understandably unrecoverable data on damaged disk blocks

But the bad blocks DO exist in real life - you can not just ignore them! Reiserfs design NEVER ever considered this facet of life: if you have ONE bad block in wrong place - you are screwed 100%. When disk size is 512 bytes and HDD size of 2TiB loss of a 0.0000000003% of your data means 100% of your stuff is lost. This is not even funny.

XFS is also not a good idea (I was biten by it too) - but here we have bad implementation, not bad design. Implementation can be fixed, design mistake is unfixable.

I certainly don't disagree; I was referring to the data actually on the damaged part of the disk, which I wouldn't reasonably expect to be able to recover without great expense.
