I've got two WD 600GB external USB hard drives with my music and videos. The second drive was running a norton backup of the first and my C documents. Norton and I are no longer speaking. They tried to run my canceled bank card a month early for payment then had the nerve to email me about it. Running the bill a month early could have played havoc because the card was tied to my checking account. I got an american express gift card big enough to pay for the subscription and ran it two days before the expiration.  They tried to get me to buy Utilities that were already included in 360, then they tried to tack on a PC insurance and raise the price another $10. They refuse to accept a card that Amazon has no trouble running. They insist I give them an active credit card tied to a large account they can hold and automatically bill for multiple years. The IRS throws away my bank information every year because they don't want to be responsible. Does norton really believe their security is that good? I don't so I guess I need a good backup program as well.

I have most of my Bryce work in My Documents. It takes up 148GB on C:.  The first Western Digital only has 47GB free so no way it's all going to go. I can really see myself filling all the space back up in six months.

I was already leaning toward Cloning the vista system to a terabyte drive. The WD caviar Black 1TB SATA drive sells for $89.99 I can swing that. Once there I don't know if I can go any farther. From the System Control Panel I get the Gateway is running an AMD Phenom(TM) 8400 Triple Core Processor 2.10 GHz. System Type says it is a 32bit operating system. The last time I upgraded from 98 to XP it lasted about a month then crashed. I wound up reformatting and installing everything again anyway.
