think about this .for the dj/kj that have more than one system if you own two sets of disc or you buy two or more hoster to impeg faster you have a problem. the problem is hoster is not set up to combine two hard drives to make one .it has no way to pick up dup id number and give you the chance to change the id # in the kma file . so when you rebuild the data base you don't screw up all that work you have done. if you have 1000 disc and your lucky enough to do 5 an hour and you dont have the time to do this your self . and you can find some to do this for you .lets say for 10.00 an hour you do the math sure is a lot of money to spend so you dont have to carry your disc around .look mtu has done a great job with a new baby. but kjs have to back of with things like key change and let them focus on more important things like data base and multiple hard drive fuction.do you really want to spend 250 hours do 1 set of disc thank you mike
