I recently replaced my 286/20 motherboard with a new TP386/33 [Technology Power Enterprises] and am now having problems transfering data between my floppy and hard drives. My system consists of the TP386/33 with a 64k cache and 8Mb of 80ns memory on the motherboard; an Adlib card; a Microsoft InPort mouse card; a generic I/O (serial/parallel) card; a Microtek scanner card; a Paradise 512k VGA card; a monochrome (secondary monitor card); and a generic Western Digital RLL controller. My drives are: 1.2Mb, 1.44Mb and a 65Mb Mitsubishi MR535. I have no problems reading from the hard drive, but when I try to copy stuff from one of the floppy drives to the hard drive, some of the copied data becomes corrupt. This only seems to occur in files > 10k, and happens most often with binary files. I occasionally experience strange problems running programs from the floppies as well (e.g. system hangs while installing Windows or such), but these two problems probably have the same cause. I have run Checkit on my system, which reports no DMA problem. Sleuth indicates that I have no conflicting interrupts.. I have swapped out the hard drive controller with another generic RLL card, and with an Adaptec 2372 card, with the same problems [each time, reformatting my hard drive]. I've also swapped out my floppy and hard drive cables, and have switched floppy drives as well. Any ideas would be greatly appreciated. As a side note, should I be using 80ns memory? The dealer who sold me the machine didn't have any 70ns ram, and told me that there wouldn't be any noticable difference anyway... Should I return the ram and get 70ns?
