Hello there ! I've recently bought a LACIE Neil Polton USB 2 1TB external Hard Disk and connected it to a USB hub where already stand 2 more Lacie external drives (previous generation). I use them with my iMac Alu and Leopard 10.5.3. The issue is that when I put the iMac in the STOP mode, all the other 2 discs (1 of them is for Time machine) correctly stop [led on, spinning off]. But the new disc is stucked ON: led on and spinning on. That's noisy and annoying... Some more info: - the new disc is Mac OS Journaled formatted and it's just for archiving videos and other stuff; - all the disks are individually powered with AC cord; - all of them are connected to the same Hub USB; - the new disk and one of the old disk have a switch (just on/off positions) on the back and - of course - they're both set to ON; - I've tried several time to reboot the system but no luck. Any guess on how to make that disk sleep, too ? Thank you !
