hello all

so the troublesouting of this later is to change drive ?? are you agree?

[sdo · Accepted solution]

Who on earth can say whether a tape drive needs changing based upon a snipet from an activity monitor job log.

Why don't you try googling for :

critical bptm attempted to write it is not a multiple of 512

...which throws up some interesting posts.

Then, why don't you filter and follow those articles first for yourself, and then come back to us with your own findings if / when you get stuck.
