Ok so i have my computer, its: Dell Dimension 8200 Intel Pentium 4 CPU 1.80GHz Processor 512MB Ram 40GB Hard Drive. I am currently running Win XP Professional Version 2002 Service Pack 2 So i only have less than 2GB left of space on this drive and seeing that new HD's have dropped significantly in price lately i'd like to buy one and install it. Now, I of course have a lot of information on this drive i'd like to keep so i want to save the drive. What would be the correct sequence of actions that I would need to take in order to complete this task as effectively and efficiently as possible? Also, I dont know WHICH drive I need to buy. I see some terms like SATA and others being thrown around and I really dont know which is the right one for my computer. If you guys could point me in the direction of a good HD I could use on this computer, I'm looking for 150GB-200GB for starters. A link to Newegg or TigerDirect would be helpful. Thanks dudes.
