sounds pretty weird, almost like the label may say 7208-234, but look at the config on the system & see if it says 7208-232, or check config of unit to see if it has a "232 mode". The 232 limit was 5gb. I've used the -234 with 7gig tapes before. Also, is yours in a migration tower? Requires certain features to support the 234. May have an incompatible feature card. jim ----- Original Message ----- From: "Urbanek, Marty" <Marty_Urbanek@stercomm.com> To: <firstname.lastname@example.org> Sent: Tuesday, December 11, 2001 4:40 PM Subject: Re: 7208 @ 7GB > Jim, > > From V3R2 System handbook: > > "Each drive of the 7208 Model 232 provides up to 5G of data per cartridge, > and the 7208 Model 234 drives provide up to 7G of data.
