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.

Because it has no burner and there was no report of which O/S there is a possibility that it could be an old system with USB 1.0. There might be a problem with a flash drive. Unlikely, but possible. I did have one work one time an an old laptop with Win2000 and USB 1.0. Then I have had a couple old systems that wouldn't. DA

More memory is good but at some point there is a diminishing return on the investment and that point is a function of what you are doing with your computer. Things like first person shooter games, video editing, photo editing (of very large files) all benefit from lots of memory. Writing an email to Aunt Betty doesn't require very much memory at all because the computer can process information far faster than you can type. Same thing for the Internet, your computer can render pages faster than your connection can supply the information. So if you have a slow internet connection, you're not likely to experience much, if any improvement. With that said, 4 gigs is probably a pretty good number. If you really want a WOW factor, get a solid state drive and use that for your O/S and critical applications. To try and answer some of your questions: - Windows doesn't care about the physical drive or any logical partitions. It does make good sense to install Windows 7 on the newer, faster drive. You'll get the best performance that way. When it comes time to get rid of XP, everything will be on one drive and that, if nothing else, should help you keep things mentally organized. - My understanding is that you have two physical drives, one with a functioning version of XP and the other blank. If that is not correct, say so NOW. - When you go to install Windows 7, it will recognize that there is another operating system (Windows XP) already installed. Windows 7 won't do anything to XP other than to set up the dual boot. Essentially it's computer language that says, "XP is there, Windows 7 is here, which one do you want to use?" - Logical partitions to a drive a largely a function of personal preference. Understand that it is more difficult (but not impossible) to non-destructively repartition a drive after you put data on it. If you, for example, have a partition for music, another for videos, and a third for pictures and find down the road that you have a lot more videos than music, it becomes more difficult to rearrange things. My suggestion is a single, large partition and use folders to organize your data.

Is it an HP? My son put 6 new hard drives in his HP laptop and they put in multiple motherboards in a 2 year period. It was a lemon from day one and I had to fight tooth and nail to get them to completely replace the computer. I kept escalating until they ran out of people to send me to - had a record of every call and the resulting lack of follow-up. I know every computer mfg has customers who love them and those who hate them. None of them are a bargain in the customer service arena as far as I'm concerned.
