I was wondering what the best way to copy 2 hard drives to one large primary drive? For example: copy all music from one 30gb hard drive and one 40gb hard drive to one 160gb hard drive? Then I was going to buy a IDE to CF converter and buy CF cards. Like the ones below.

ide to cf converter, holds 2 CF cards

128gb CF card like below, just get a 256gb or 512gb

So then wondering if it would be the same technique to copy over to the large CF card as it would be copying to a large IDE hard drive.

So what is the easiest way?
