Hi, Quoting "Yiying Zhang" <yyzhang at cs.wisc.edu>: > When I try to compile disksim on a 64bit machine Yes, disksim currently doesn't compile on 64bit machines. I did some corrections and get it to compile, but I didn't publish any patch up until now. Thank you for reminding me, I'll try to get that together. Regards Markus Wanner
