No. And I see no useful purpose in including that

If the read was recovered, you have the data; surely you would
*not* want to recreate a tape and make a previously marginal
block, marginal again on a clone?
Choosing between the loss of all the data, and a partial
copy, I'll take the partial copy.
I have many 8-inch disks with bad blocks. I'd like to preserve
the data if at all possible. A simplistic 'dd'-style read
won't preserve everything; it'll bail out when it has a problem.

I just did a 'dd' of a bad QIC-80 tape; it read the entire tape
as a single file, and didn't bail out.
I've not done that with magtape, but ISTR someone else here
saying that 'dd' does raw reads, bad blocks and all...
My bad if not true.
