I thought most filesystems had a file-entry section, with all the metadata, permissions, etc, and a file data section, which contains the information of the actual file. I guess I wouldn't be surprised if the metadata being edited were corrupted, but to corrupt the file data/location seems odd to me. Especially with soft updates; unless I'm mistaken, that's what it is supposed to minimise. -Jim
