If the tape is streaming but the next block is not quite ready, the drive can write an extended inter-record gap and then the data when it arrives. If the data does not arrive within a certain time window, and the drive has to stop and reposition, the extended gap is re-recorded as a normal inter-record gap. The extended gaps can really chew up tape if your system is on the brink of stopping streaming. -- A. Lester Buck ...!texbell!moray!siswat!buck
