HP is solving its HP 3000 operating system release tape problem, announcing that after July it will no longer ship its update DAT cartridges in DDS-1 format. Customers noted during March that their HP tapes wouldn’t mount on the newer DDS-2, DDS-3 and DDS-4 tape drives. HP went to all-DDS-3 devices with A-Class and N-Class systems. 7.0 Express 1 and 6.5 Express 3 updates brought the problem to the surface. The 7.5 release this September will be the first in the new DDS-2 format, which the DDS-1 units don’t read.
