Q: How much data will an 8mm tape hold when used with the Jetstream drive?\
\
Q: What size should I specify for the `s' parameter of dump(8) when using the Jetstream?\

\pard\tx520\tx1060\tx1600\tx2120\tx2660\tx3200\tx3720\tx4260\tx4800\tx5320 measured the capacity of 120-minute cartridges thirteen times and came up with the following figures:\
