[Disksim-users] runvalid produces funny answers

[Tetrick, Scott]

Has this been always the case?  Latest version of DISKsim 3.0 from the
website, and after I get it to compile, both on CYGWIN on windows and
Redhat with 2.4.9 kernel I get some significant differences.  Are these
differences known?  Is there a fix, either in runvalid or in the code?
 

The remaining tests exercise other DiskSim components
