I'm not sure how you set up your backup drive, but mine only backs up files periodically according to a schedule. The schedule I chose was to backup at 3am when I'm not using it. In my experience, when the backup drive is copying files from the main hard drive, the main drive might respond a tad slower. However, being on the Internet and surfing to things like Facebook shouldn't really be affected unless you are trying to upload pictures, etc., while the backup is running, especially since it sounds like you have a newer computer with probably adequate RAM. You may coincidentally have something else going on.

I surprisingly ran into this same issue. I've called HP before, the first time being when i took my new Pavilion Slimline out of the box and the hard drive was not being recognised. I called and was immediately told that it was no longer under warranty. I said i had just bought it about 4 hours ago at a major retailer. I was told it didn't matter, apparently it was an older model that was on the store shelves for some time now. Four calls and three hours later my computer was working, sort of. I had a few calls in the past 9 months, usually for not booting properly or at all. I'm still waiting for recovery discs from about 9 months ago. Last night i came home and my computer was frozen. I had to reboot it. It ran the CHKDSK (again) and afterwards i was missing about 100GB of data. I called HP today. After he said his greeting i opened with "pending hard drive failure". There was no talk of recovery discs. He had me run the hardware diagnostics. Surface scan : HD535-2W. The fun lies in finding a service location in Calgary. He said they had service centres & partners EVERYWHERE. Their server was offline so we couldn't get it from their website. He gave me businesses to call. In a city of over 1000000 people you'd think there would be SOMEWHERE i could go to have the hard drive replaced. He was very helpful. I just wish their computers were too. It would save me all of these calls, from which i am taking a break. This would be the first time i got someone who really listened to me too. It's really nice when that happens.

I may be wrong, but I think you can only use external drives as main drives if they're SCSI or SATA. If you're dealing with USB devices, they're too slow. Some programs will not install on external drives. I may be misreading Ravencajun's last sentence. If you're looking for an external drive, you want to make sure you get something that is a portable drive. It would probably include all the cables. For a laptop replacement drive, you don't need the cables. What is probably the easiest way to upgrade a laptop hard drive is to get one of these EZupgrade enclosures with a drive. The nice thing about the enclosure is that it will work for either SATA or ATA. It includes software so that you can basically do the image and restore in one step, then just swap drives. Since your laptop is 5 years old and had a 6 gb drive to start, it's probably ATA/IDE/EIDE rather than SATA. You could get something like this with the EZ upgrade for less than $100. You'd put the new drive in the enclosure, run the software to clone the drive, turn everything off, pull the current drive, put in the new one and if all goes well, you can just start right up.
