A customer has a TS3500 Tape Library with LTO-3 drives installed. As part of a hardware
upgrade, the drives are being changed to LTO-6. The customer is concerned about reusing
the existing media, including already purchased but unused tape cartridges.
What advice should the technical specialist give the customer?

A.
None of the tape cartridges will be writable, however, the data can still be read by the
LTO-6 drives

B.
Retain the written tape cartridges for later recovery; the blank media can be used for later
writes with a lower capacity than LTO-6 specific cartridges

C.
Retain the written tapes and a LTO-3 drive for later recovery; blank media will be
unusable with LTO-6

D.
Tapes written by LTO-3 drives will not be readable by LTO-6 drives; blank tapes can be
formatted for LTO-6
