I had a client with this same issue. However, her issue was that the top left USB port would only accept flash drives. Your external harddrive is probably not getting enough power from your USB port. Try using two USB ports (you can get a connector for this) to power up the external harddrive.
The Evo N610c is upgradable to only 1GB of memory. You're overloading the motherboard, it can't handle 2GB. If you really need 2GB, get a new laptop (or a PC, for that matter). Otherwise, I'd run (2) 512MB sticks of RAM to even out the workload.
did you connect directly to your laptop or you connected via external USB Hub?? Your notebook model should support USB 2.0 ...so it should not face the problem you post..unless you're not connecting it directly.
Each memory slot on the C555NR can support a maximum of 1GB of RAM. There are actually 2 slots, but only one is easily accessible to you. By upgrading both the primary and secondary DIMMs, you could achieve a total of 2GB of memory but you would have to remove the 512mb chip that is already installed and replace it with 1GB (+1GB in the expansion slot as well.)
If you don't plan on taking the computer to a professional to be serviced, you will probably only want to upgrade the memory in the secondary slot located under the memory cover on the underside of the computer. It can handle a 1GB SODIMM.
FYI the memory is: 200 Pin DDR2-533 PC2-4200 SODIMM
