Yesterday I bought a "standard" Lacie Desktop Hard Disk 1TB. http://www.lacie.com/se/products/product.htm?pid=11164
The problem is that the computer hangs at bios start up and the LEDS shows "Initializing Floppy Drive Controller" (After "Initializing Hard Drive Controller").
If i boot without external USB disk attached everything works find and the external disk works if i connects it later.
I have searched "the internet" and have found the same problems with Dell computers and Asus motherboard for example.
I have tried many different settings in BIOS but nothing works (enable/disable USB legacy support, PnP aware OS yes/no,enable/disable Floppy etc.)
Best Regards Peter
P.S I don't like the "Then disconnect it when you boot!" solution....
