The reason for my question...
My current computer has a 20G drive, partitioned into 4 partitions because that's the way I've been doing it since the days of my 386. But now I've decided I don't want so many partitions, partly because I want to run multiple drives now and partly because I have a lot of drive letters with my 4-in-1 card reader.
I was going to buy a pair of 120G's and set them up as C: and D:, but larger drives are close to the same price, and my DSLR will probably chew up all of that space quickly anyway. I could probably get by with 120G for that use, but also I've considered running a DVR on that same computer which could benefit from all of the space it can get.
When I put in new drives I'll probably switch to XP at the same time. I don't think I want to run NTFS, and I'm not too keen on running additional 3rd party drivers.
As I understand it, to run a big drive you have to have a bios or controller that recognizes the large drive, and you have to have software to partition and format the large drive. I've read that the latest version of MS fdisk and format will go up to 127Gb partitions.
Back in the days of MFM, RLL, ESDI and IDE drives, I knew all about how to get larger drives to work with the computer and the OS. Then when IDE's started getting big, it became more "plug and play" and I didn't keep up with the technology. Now the size of drives has caught up with everyone's wildest dreams of future hard drive sizes so again we're into the world of "tricks" being required to access the full size of the hard drives.
