I have a design to improve ext3 so that one could salvage all files, even if you accidently reformated the partition, Available at http://std.dkuug.dk/keld/lazy3.txt This design has been reviewed by Ted. I also have some patches for debugfs to undelete files in ext3, available at http://std.dkuug.dk/keld/readme-salvage.html best regards keld _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
