Mirror drives in Win2k Pro

Hi experts- I'm not sure if my task is possible. I seek to run a mirrorred drive in a Win2K (PRO) environment. Any ideas or thoughts?  As always, I appreciate your talents.

best regards,  Pat

It's pretty simple.  I assume you're doing it in the Operating System and not on a RAID controller, or you'd be asking a different question.  Just ensure that the drive types are the same.  I'd--assuming IDE--connect one drive as the master in IDE1 and the other as the master in IDE2.  The rest is in computer manger--> Disk Management.
The following is a quote from W2K Disk Manager Help:
"To create a mirrored volume
Using the Windows interface

Open Computer Management (Local).
In the console tree, click Disk Management.
Where?

Computer Management (Local)
Storage
Disk Management
 
Right-click the unallocated space on one of the dynamic disks on which you want to create the mirrored volume, and then click New Volume.
In the New Volume Wizard, click Next, click Mirrored, and then follow the instructions on your screen.
 Notes

To open Computer Management, click Start, and then click Control Panel. Click Performance and Maintenance, click Administrative Tools, and then double-click Computer Management.
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
You can create mirrored volumes only on computers running Windows 2000 Server, Windows 2000 Advanced Server, or Windows 2000 Datacenter Server.
You need two dynamic disks to create a mirrored volume.
You can mirror an existing simple volume.
Mirrored volumes are fault tolerant and use RAID-1, which provides redundancy by creating two identical copies of a volume.
Mirrored volumes cannot be extended or striped.
Both copies (mirrors) of the mirrored volume share the same drive letter. "

You'll hear a lot of OS RAID has a lot of overhead, but I use it periodically and don't really notice a performance hit.

I'd ensure that all of the latest service packs and hotfixes are applied prior to implementing the RAID.

It's a nice way to protect your files :-)

I concur with 2hype - 2000 Pro, XP do not support software RAID 1 - only software RAID 0 - which you don't want to use because there is no redundancy in RAID 0, just better speed.

Thanks  gpriceee    -   It sounds pretty straight forward - You are correct that I am NOT using RAID.  These are straight IDE 60Gb HDDs.  I'll be trying it today.

Thanks to all for your assist.

regards,  Pat

I don't know how you can take back you acceptance of my answer, but you should and give it to 2hype.  The least amount of my time is spent on workstations, and I verified that 2hype is accurate: "software raid is not supported in W2k professional."

I use it on some servers.  At home, on one of my workstations I have a Promise RAID controller with 5 drives, and it has been working just fine for 3 years (I store my digital pics there).  Here's a link to some Promise controllers which you can get as cheap as $90.  Keep in mind the PCI interface when you choose the controller.

http://www.cdw.com/shop/search/Results.aspx?key=promise+technologies+raid&filteredsortorder=priceasc&idesc=1&platform=all&swn=1

So you know, the advantage to using this over software RAID is that you probably plan to RAID the Operating System.  When you use software RAID on the OS, you need to understand how boot.ini works in the event of a failure because the software itself informs itself of the disk and partition upon which the OS resides; software RAID on failure needs boot.ini adjusted when it fails.

The Promise RAID controller--or any hardware RAID controller--delivers the disks pre-mirrored to the Operating System, so the OS has no idea how many disks have been included in a RAID and delivered as "one" disk.  In this scenario, if one disk fails, you don't have to worry about changing the boot.ini after a failure.  Also, if you are interested, some of the controllers allow for hot swapping the drives; they start at twice the price, around $188.

Note to gpriceee & 2 hype - OOOps - You both told me that I require Win2k Server version to perform this task - I should have read further. I will look into splitting those points.  Thanks again
