Ok, well I share my hard drive on my windows machine with my mac, my mac and my pc are on the same router and they are both running at 100mbps... Sometimes when im connected to the shared drive on my pc, through my mac... Im usualy copying mp3s over from my pc to my mac... It was going DOG slow... about 30 sec for a 3mb file transfer!! But then a day later I was trasferring files again... it took no time at all to transfer them, they were going at a very reasonable speed... what the heck is up with that? Cause right now again, its going very slow.. and I'm impatient with it... how can I fix this? Why is the speed changing? Any way to fix it?? thanks...
