I have a USB Hard disk that I am using as a secondary drive just for extra storage. When this is attached and I start my PC the second screen says searching for mass storage dives for about 5 minutes before continuing on. The same happens when I have a USB pen disk attached upon boot. If I attach the device after the PC has loaded then it is very quick however plugging and unplugging is not ideal. Is there away to disable this in the BIOS as I cannot instantly see an option. On boot it informs me I have an American Trends AMIBIOS in the BIOS setup it states the version as v02.58 2006. This is running on a ASUS MV2 Motherboard.
