I love my thumb-drives. I recently added a high-speed 8GB SanDisk USB Blade to my setup. I already have a slow old 64GB drive that I use just to backup my file archives, a 32GB OCZ Rally2 (that I've hidden from Windows because I have a full install of Linux on it that I can boot into), and another old 1GB that I've had for years. When I plugged the new Blade into my PC, my 120GB SSD boot drive "vanished" from my BIOS. When I unplugged the Blade, my SSD returned, I was sure that meant my new thumb-drive was bad. (I can plug all 5 drives in AFTER booting and the SSD is detected just fine, I just can't have them all plugged in BEFORE booting.) So I tried an experiment: I unplugged ALL of my thumb drives and plugged them back in one at a time, starting with the Blade. The SSD didn't "disappear" until after I plugged in my 5th thumb-drive. Tried different drives in different ports. It didn't matter. My SSD disappears from my BIOS with all 5 drives plugged in. I have two USB expansion ports on the front of my case, 4 more USB ports in a hub in a 3.5" bay, 6 USB devices plugged into the back of my PC including a 7-port hub with just one device plugged into it. I've never heard of something like this happening before. And USB-2.0 is "technically" capable of supporting 64 devices. So why is my PC barfing on one drive too many? Anyone else ever have a problem like this, where a USB flash drive "conflicts" with a SSD flash drive?
