Lucid Lightning Problem!

I just purchased Lightning for Windows, which allows me to cache my cdrom drive. I am having a problem with it. When I go into to windows, and look at the cache drive list, it never lists my cdrom drive. Further it seems to mess up its knowledge of my logical drives which are really superstor compressed drives. Anybody seen this problem? Regards, David

I've heard of similar problems, and they all involve disk compression software and caches. Disk compressors actually roll your entire disk contents into one huge file save for the boot information, etc. Many people have had Windows bomb simply because they forgot to exclude their Windows permanent swap file and it won't work right within a compressed environment. Caches, too, must be external to work properly unless they are SPECIFICALLY for the compression program (or the compression program specifically acknowledges them), which brings up the question of whether the CD ROM and MSDEX drivers are inside or outside the compression program. Maybe they can't see each other! Many caches are incompatible with Stacker or Superstor or both, since they are ignorant of the compression and thus never see the "virtual" drives. That sounds like your problem. If so, contact the cache maker but I suspect it's "Sorry about that."

Jack, PMI, but I need to clarify a number of statements you made concerning caching which is incorrect. The difference in caches that work with Superstor and Stacker vs. do not have little to do whether they are written for the product. More likely it has to do with what level of your computer's operating system the cache is operating in. For example, FAST! is a BIOS level product. Because it operates at the BIOS INT 13 it ignores all of the 'fooling' that a product like Stacker tries to do at the DOS INT21 level. A lower level product will always offer better support for these types of pro % MONNCI Network connection interrupted, possible data loss. [Attached, running] % Choice required. To exit type EXIT. For help, type HELP.

Jack, Thanks for your note. I called Lucid, the cache folks, and explained the problem. They say they can tell if a logical drive is a compressed driver or not. Interstingly enough, one of their programs that displays all disc drive is able to tell, but the control program has a bug, and they acknowledged it. I am going to call back in two weeks. If they don't have a projected time for release of a fix, back it goes under their money back guarantee! Regards, David
