The documentation is far too short. Does someone have a good explanation for how this works? Even better, is anyone aware of a tool to automatically extract this from a disk and generate the parameters? I've looked at DIXtrac, but it says it doesn't work with serpentine drives. It also can't deal with the fact that the disk refuses to report how many cylinders or heads it has. I have output from DIG, but I don't know how to convert it for DiskSim.

If so,how? 2)I cannot find any soruce code about RAID5 reconstruction in disksim. Where is the reconstruction algorithm for RAID 5 in disksim? How can I load my own reconstruction algorithm to disksim and execute it? Thanks very much! Ivy -------------- next part -------------- An HTML attachment was scrubbed...

Disksim is great for disks but the RAID model is pretty broken.
