Whoa, hold the phone! Someone just told me of some equipment you can get to increase the capacity of your hard disk. This equipment consists of a couple processors and it basically does compression/decompression REALLY FAST on the data. Sounds very cool. Yeah, I'm suffering from the common hi-tech syndrome. "I want more! faster, smaller, better, (cheaper)" Does anyone know of any products out there that do this? I'm sure they exist, but who makes them (and how much (I'm a college student))? Thanks a lot! Pete peteru@icarus.pen.tek.com

Your suspicions are correct -- there is no free lunch. Greater compression
means less redundancy, means HIGHER ERROR RATES for magnetic media (gross
generalization -- well, maybe not so gross...)
Media which use extremely high densities must use more, not less bits, to
represent the same amount of data -- and interleave it to protect against
burst errors.

This equipment consists of A year or two ago I had a board that gave me ~3 times the capacity of my ST238. It was called the KXP-230Z from Konan Corporation in Tempe, Arizona. It required about 8k of DOS memory to use as a look up table. It also requires that you "partition" your disk in their format. I loved it. The ONLY reason that I had to give it up was that there was no support software for it like Norton Utilities. In a production environment, I sometimes mess up and erase a file that I shouldn't have. Norton Utilities (unerase) thought that the file was recoevered, but it wasn't. Maybe they have tools for it now. If I remember correctly, it cost ~$250. I don't know what they go for now, or if they're still in business. I also tried it on an "80MB disk and ended up with about 8 logical 30MB drives. As I said, it worked great and is fast. ---- Doug Marshall <Doug.Marshall@SanDiego.NCR.COM> +1 619 485 3494 <...!ncr-sd!palomar!dougm> "All of us is smarter than each of us!"
