You have K-Class and I assume DDS drive must be slower than DDS4 drive.

As such, the make_tape_recovery process will take between 40 to 60 minutes.

(K260, 2CPUs, DDS3 tape drive).<BR /><BR /> Thu, 25 Mar 2004 08:56:08 GMT https://community.hpe.com/t5/operating-system-hp-ux/how-long-does-it-take-to-make-tape-recovery/m-p/3229156#M894239 Steven Chen_1 2004-03-25T08:56:08Z
