It may be the only thing that makes sense is to keep a copy of the original i_blocks array, and then restore it after the truncate is complete and i_links is set to zero. Even if we don't recover the indirect blocks, at least for small files people will be able to recover their data.... - Ted _______________________________________________ Ext3-users@redhat.com https://listman.redhat.com/mailman/listinfo/ext3-users
