Imaging - Compression error (-2)
Posted: Wed Jul 28, 2021 10:58 pm
Hi Jon, firstly thanks for creating ADFFS and the whole preservation initiative, it's really great and much appreciated!
I'm trying to make a JFD image of Chocks Away Mark II disc 1, and I'm getting "Compression error (-2)" towards the end of the process. This is with my own recording file (I think my discs have some additional files saved on them). I was able to image Saloon Cars discs 1 and 2 successfully, so in general it works on my machine. I saw that in the past this error occurred when using the ROL version of ZLib, but I don't have this so it's using the ZLib module provided with ADFFS. This is with ADFFS version 2.73 on a 4MB A3000, ARM2, RISC OS 3, ZIDEFS hard disc.
I don't have anything installed on the machine so there's no nested wimp or whatever it is that is needed to populate the imaging menu with the titles, so I edited the DATA statements so that I only get offered the one title that I'm going to image and that seems to work OK. By the way, there is a small bug if you try to image without populating the data - the program tries to read nonexisting system variables and the call to PROCerror fails because the parameters are wrong (I guess it's left over from an earlier version).
Any ideas about the ZLib error? Thanks!
