the first 23MB - it'd be nice if there was a way of skipping over the

I'm not sure what algorithm is used for ".Z" files. For ".gz",
the
answer would probably be no, because the dictionary is continuously
updated and a corrupt area would get completely out of sync, with no
obvious means to guess what the intervening dictionary updates should
be.
If ".Z" uses a simpler algorithm with a fixed dictionary (either
completely fixed, or fixed for the duration of one file), recovery
may well be possible.
