USB boot and SATA data drives
I am running the 18.104.22.168 kernel on a RedHat 5.3 X64 bit OS. I am booting off a USB compact flash. When I put two hard drives in a test system the OS does not allow me to access either, however if I have one hard drive inserted I am able to mount the hard drive fine. Extremely strange. When both hard drives are inserted dmesg reports a sde and sdf, it just will not let me access them. I am not sure if this is a hardware issue or OS.
fdisk /dev/sde says unable to open. smartctl -i /dev/sde says NO Medium found. When I boot with only one inserted i am able fdisk. mount, etc... /dev/sde just fine.
The USB controller has 5 slots to insert various media, but I am just using it for its compact flash slot.
Why will the system play nice with one hard drive and not with two?
