The ONLY reason I would personally put an OEM hard disk back into the CPU is for just that reason - to keep things in it's original release state regarding the hardware. Beyond that, there's zero technical reasons for not upgrading. The OEM drive was 20.6GB generally because they were readily available. The Mackie D8B operating system (
V5.1) uses a 3GB+ sized image at runtime. This EASILY fits onto a 4GB compact flash card, using an adapter and a PCI bracket extender so you don't EVER have to open the CPU back up again; most likely only under the most dire of circumstances. Because of the small size, udma is taken out of the picture and you don't have to be concerned with a True IDE mode (
cf card related) during boot up just due to the small size of the image. It doesn't corrupt (
easily if at all) due to no moving parts. It's also quite inexpensive... it just make NO sense not to upgrade...
However, you knew it was coming so here it is :
