I will have no problem with reinstalling the os then Right? The Bios will allow acces to the dvd drive. even though I have a clean system.? I know it is a stupid question, but I always wondered when someone built a computer how they ever get to load the driver for the External drives to install the OS? Dan

This means on any system for several years time you have the ability to boot from an optical drive, and the windows CD follows a bootable disc spec for that. The booted windows installation cd runs as designs and takes it from there. After deleting the array you just have to have already decided if you were going to install to a single drive that was formerly in the array, if you were wanting to set up a new array (which you may need to do BEFORE booting and installing windows to the array) by defining it in the raid controller bios menu (separate bios module, usually accessed by a keystroke after main bios module has finished running at boot-time), or if you instead wanted to install to some other drive.

Thank you for your replies. This information was exactly what I was looking for and is very helpfull to me. Raid can be so confusing. Thanks again, Dan |
