Does anybody know what this means: EXT3-fs: hdc1: couldn't mount because of unsupported optional features (4000400). I googled but only found questions. I can read the disk (both fdisk and dd are happy enough), but I don't want to overwrite anything if I don't have to. # uname -r 2.6.20-1.2944.fc6 -- Sjoerd Mullender
