cannot drop empty chunk ?

During a reorganisation of the disk usage we tried to delete some chunks. Before doing this we dumped all the data into ascii files (so we can reload them afterwards), and dropped all tables. All chunks should be empty at this point. But running the command "onspaces -d ..." gives the error "chunk not empty". The output of "onstat -d" also shows that the chunk still contains data. However if we run "oncheck -pe" nothing is in this particular chunk. What could be causing this or what are we missing ? Thanks for any help.
