Guy,

yes, in fact I noticed that 'MOVE DATA' is very fast compared to
reclamation processes, but sometimes doesn't solve the problem of
cassette which reach >90% of reclamations packets and still mantain a
packet utilization of 50-70%. I guess this is the case of very scattered
data on the media.

Thank you

Mauro
