Hi,
I don't know how important it is. I have a damanged partition under
Linux. There are some wild files under /lost+found. All of them are
device files with strange values in st_size and st_blocks. As the
result, du gives some wild numbers on them, something like "216T".
Here is a klude I use. I am not very sure if it is 100% correct.
Thanks.
H.J.
