Hi, With all the recent problems we've had on our internal HD, we are looking to buy an external HD to store our backups. Can anyone recommend a good external 500+ gig HD. I have a Dell Dimension 8200 running XP. I was told by Dell that I need to buy a new USB 2.0 PCI adapter. They recommend D-Link 2 port USB 2.0 PCI Adapter. I also want to buy an external HD for my laptop...Dell Latitude D600. Any suggestion will be greatly appreciated.
