The drive attempts to maximize transfer rate and reduce repositioning by writing a filler block when a write isn't followed soon enough by the next write. This never crossed my mind before, but I imagine a carefully-written program with precisely-timed misses could minimize capacity by maximizing the number of filler blocks inserted by the drive! In practice I've been able to count on at least 80MB. tar will stream the drive on your DS2100. ---Pete kaiser@cheese.enet.dec.com +1 508 480 4345 (machine: +1 617 641 3450)
