I use Novell DOS 7.0.15 and get errors in copying large files to floppy disk. I detect the errors using COMP. Typically, there are between 0 and 7 errors (different bytes) per file (I use three 350kB test files). I have found that if I clean boot, then the errors disappear. Adding other programs makes the errors recur. However, after many, many tests I have yet to establish any logical pattern in the results as to which setups work and which don't. The same problems occur with DR-DOS, but *much less* frequently with MS-DOS (i.e., only 1 file mis-copied out of 135). The system is an AMD K5-PR133 on an ASUS TP24 motherboard (onboard i/o). There are absolutely no problems on my 486 system running the same Novell DOS version. I have tried swapping the floppy disk drive (and cable) from my working 486 system, but this made no difference. The remaining possibilities are something to do with DR/NW/OpenDOS, the motherboard, or the cpu. Any thoughts and opinions would be appreciated. Cheers Andrew McLachlan, PhD student.
