I would yell at them to fix it but they did this 26 years ago

good news: it's a rar archive! That means we can get partial data out, right? because RAR has per-file headers, not a big all-in-one header at the end?

BAD NEWS: it's a solid archive.

foone OP , vor 10 Tagen

RAR solid archives compress all the files as if they're one single block of data. This means to extract a file N, you have to have decompressed all files 0 to N-1.

and the disk we're missing is the first one.

foone OP , vor 10 Tagen

the question is if we can cheat.
we've got 6 disks, checksums for all the files (some of which we may have elsewhere), can we recover the dictionary enough to let us decompress the disks we do have?

@foone link the file? :blobcateyes: i'm heading to sleep right about now but i want to have a crack at this first thing tomorrow morning

foone OP , vor 10 Tagen

@domi I don't have a reliable copy of it uploaded anywhere yet. I'll put it online when I can. (it's inside a torrent inside a torrent of a bunch of zips containing zips containing rars)
