Re: Raid 5 failure
To recover your data is very easy. just slave your hdd to a system that is working fine and switch it on.after windows has succesfully loaded go to my computer you will see to hard drive.the slave hdd will be labelled B.double click on it go to my documents and copy all your filesand save it on your working hard drive.after copying make sure you remove the slave hard disk

This is a complex and diverse question due to the numerous scenarios.
A common setup: Dual servers setup on a fail over cluster. You basically make two servers seem as one with a virtual IP and name. Hardware breakdown is 2 servers with 5 drives each minimum. The first 2 drives the OS at RAID 1 (mirrored). The other 3 drives are the database at RAID 5 (striped). You now have hardware redundancy all the way around. When 1 drives fails, you simply replace the drive. The database is replicated and is fail safe. When a complete server fails or needs maintenance you just roll over the server / database to the other node via cluster administration.
This is just an example, but a very common SQL server setup in busisness enterprise environment.
depends if the raid configuration is made by hardware or software
if its made by hardware you can find how to define the raid in the bios or using the server's start disc to start the windows 2003 installation
1. If you are just setting up your computer to have an a regular HDD and Backup HDD, i would think you should be able to set that up by booting onto your computer regularly, go to start, then into My Computer and right clicking on the HDD you want to set as Raid 1.
But if just want that other HDD for Space on your computer, all you had to do was plug it in and there you go... extra space.
Now if your installing windows 7 on the other drive i would find that pointless because you already have it on your first drive unless your putting 2 operating systems onto your computer.
First of all backup all of ur data include your database if its stored on server , any encrypted files be sure that you decrypt it first after backup , determine if the server hardware compatible with new OS , don't forget the raid configurations after all of that boot with your new system CD and let the system format the hard for you i don't prefer to use third party application if i use microsoft windows
Your problem is with the system needing a raid driver for the motherboard or the raid card. pretend you are installing windows with bartpe. it also asks you for the raid drivers. use a floppy disk with the raid drivers and let it load. that should let you see the raid drives as a set.
Your problem is a little different. since its a mirror raid. you might want to try taking out one of the drive and work with a single drive until it is fix. try doing a repair with the windows CD. seems like there are some corrupted OS files. And you might want to start a new question since your problem is really different from Compufixa's problem. Thanks
Raid 6 will tolerate two simulatneous hard disk failures. So the posibility for data loss is very less. But the rebuilting steps defers for different server products like IBM and DELL. But normaly when u change a new hard disk the server will automatically starts the rebuilding process.
You're going to need more drives. When you say Parity, we'll assume that you want to stripe the drives. For that you need 3 drives. Can you put more drives in the machine? You could put two drives in for the OS and mirror them. Then you'd have the 3 drives available for data using RAID 5 (striping with parity)
