The truncate command never releases the initial extent of the table or its associated indexes if any. In the future I have heard Oracle is going to support defining tables and indexes without allocating storage. But at present if the table/index exists it takes at least one extent.

We have done a truncate of the partition with a drop storage, and it shows storage. What's up with this? Database is 188.8.131.52 HP-UX. Michael Kline Database Administration SunTrust Banks, Inc.
