The zoom program is extremely unreliable, please don't use it! I got gurus with on a lot of occasions, crunching or decrunching. Worst case yet, on some occasions it crunches fines, then guru when decrunching! It is a pity since Zoom is faster than DMS at low compression, and at the same more efficient than the highest compresion mode of DMS. But for now DMS is still the only valid choice for disk archiving... Nobody seemed to have any problem with dms. If zoom comes out with a bug-free version, I will register it, otherwise I will have to register for dms. Apparently, zoom GURUs on disks containing already compressed files, such as demo or games. Apparently the Zoom programmer wasn't aware that compressing compressed data makes it expand, and may be overflowing some buffers... So: DO NOT USE ZOOM v4.1!!!

I haven't had a problem with Zoom yet. I've decrunched many files (haven't had a need to crunch, so I cant' speak on that yet) and have had no problem whatsoever. I liked it because it was not only faster, but I didn't need to wipe the disk it was decrunching to. It wiped it for me. I'll give it a shot crunching some disks and see if that GURU's it or not. ---- Cesi

I've decrunched many files >(haven't had a need to crunch, so I cant' speak on that yet) yes, problem are much more on the compressing side, which explains why you didnt see them: bad .zom archives couldn't be uploaded, since zoom gurued the machine... You only get to see the good ones. I have got some cases where it compressed Ok, and decrunched a non-working disk. Granted, dms is slower, but better safe than soirry. Besides, I use low compression (cmode 1 or 2) which is super-fast, although not efficient, but Ftp transfers are fast, so there is no need to super-compress files generally. And uploading a bad .zom file is so annoying, you don't do it twice! Fool me once, shame on zoom, fool me twice, shame on me! > problem whatsoever. I liked it because it was not only faster, but I didn't > need to wipe the disk it was decrunching to. It wiped it for me. DMS does it too, only slower. It would be a NICE addition to dms to use the lhlib (fish disk 436) to provide a lz-mode compression at near no programming costs for the DMS authors... Do SDS people have net access? > I'll give it > a shot crunching some disks and see if that GURU's it or not. Try on non-amigados format (games), or disks containing already compressed data (.lzh), that's the most probable way of calling Mr meditation... -- Colas Nahaboo, colas@sa.inria.fr, Bull Research, Koala Project, GWM X11 WM Phone:(33) 93.65.77.70(.66 Fax), INRIA, B.P.109 - 06561 Valbonne Cedex, FRANCE.

He hasn't access to News at the moment, but the following mail adress should work: o.barthel@a-link-h.zer.sub.org I am currently forwarding any bug reports posted here to him, but they are generally too unspecific to do something about them. However, he suggested increasing the stack size to fix the "Zoom crashes on Exit" bug. I am also willing to forward any mail to him if the above adress shouldn't work. You can reach me as holgerl@amiux.agsc.sub.org or cbmehq!cbmger!amiux!holgerl@cbmvax.commodore.com Reactions to incoming bug reports will probably appear as a public summary, since private international email is quite expensive in Germany.
