Nope. The tapelength was 33gb for 4 years, and then we found a problem last
year where amanda was calculating or writing wrong or whatever so we
lowered the tapelength to 30gb to avoid this problem.
(you can find the thread in the archives)

I simply removed it from the spool.

I've already done this.  Notice that 3 of these tapes were the same unused
tapes from the previous day.  Kindof hard to get it wrong ;-)  Move to 
bottom, change date to date prior to previous tapes.

That said, manually hacking on this in not the appropriate way to handle
this.  Why doesn't amanda recognize that it can't write this out?  Why did
it back it up in the first place?
