Problem deleting downloaded files (made by BitTorrent feature in LS-CHL)

[iwat]

   

I'm using LS-CHL running on firmware 1.07 (recently upgraded from 1.02).

 

Last few days, I downloaded some files using BitTorrent feature bundled with the LS-CHL. The downloading was fine, but I can't delete any downloaded files from LS-CHL harddrive. (tried both SMB and FTP).

 

It's quite weird because any other files in the share drive is owned by "nobody:nogroup" but the downloaded files from BitTorrent are owned by "root". I'm sure this is the cause that made me unable to delete them, but I don't know why they are belong to "root".

 

So, what should I do?

 

PS. I'm not willing to format the disk, I don't have any more back spaces left here.
