Thank you for your reply David. I am speaking more towards making sure
that the tape isn't running ahead when there are drops in the data
stream. I understand LTO-3 are variable speed, but not continuously
variable, and there can be gaps which are marked as "used" but do not
have any data on them. Please correct me where I am wrong. This
bring to mind another newbie-ish question, what are the minimum speeds
and speed-steppings?
