Just unplug the secondary tap from the 98 drive and plug in the new drive to it (no need to remove the 98 drive). Plug the new drive as the secondary and make sure the jumpers are set for secondary (otherwise it will reset your bios) (no need to format the new drive). Use your image software to "Copy Drive" (not create image). This will exactly replicate the new drive with all of the primary. Since it is larger than the present drive, no worry about compression. Unplug the primary and plug the new drive into it after setting the jumpers for a primary (you do not have to install at this time, just let it hang loose and free). Do a boot up test. I'm assuming that Acronis works like Ghost in that you have the option to create image or backup drive. If not, you'll probably want to make the meager investment in Ghost. As far as the 98 drive, I suggest doing the backup to one of the externals. Once done, remove the 98 and put in the new drive in the secondary plug. Format using full format, let all other settings at default. You will get a warning message, clidk O.K. If your getting a warning from an anti-virus program, just choose exclude. Do or not scandisk. Then repeat backup from the external to the new secondary. (PS, you may want to completely rid the external of all data so that it will not be copied to the new drive).
