Hi, I'm new to Macs. I have an iMac with 6 external disks. One of then is fw800 and the 5 others are usb and they are connected to the i mac using a usb hub. The boot process takes a very long time between black screen and white screen. After that when the system is loading it loads normally. Why does it take so long ? To make things worse, some of the disks doesn't appear on Leopard at all. If I boot on Vista they show up fine. I have tested the disks on Vista and they seem fine. All disks are NTFS. Any ideas ?
