disappeared hard disk space
Hi, all.
I need your help to find out what happened to my hard disk. The problem I've met is according to the used space in my /dev/sda8, there should be 6G left. But there's only 1G now. I can't move a file larger to 1G to that partition. Tried, but failed. I've also run some test and repairs. Unfortunately nothing's changed. Now I show you the results.

5G space's just vanished. It cannot be journal. At least before yesterday sum of used and free sizes always equaled total size, refered to "df". So far as I could recall, the mistake may be that I deleted a directory in that partition when a extraction of files was running unnoticed into the same directory. Anyhow it was deleted afterwards.
