Win2K mirroring

Dear All,


 Few months ago, I installed a Win2K server with a single IDE drive. This drive had a single partition only which occupied almost the entire disk, leaving a small unused area of around 10MB.
 Recently, as more critical data started accumulating at the server we decided to install a second disk to mirror the first one.
 So, firtly, I took the server down and installed the second IDE drive which I have chosen to be exactly the same as the first one.
 Second, I booted the server up, BIOS and Win2k recognize the drive and all seem OK.
 Third, using disk manager, I formatted the second drive with no errors.
 Next, I tried to create a mirrored volume in the second drive but Win2k tell me I have to convert it to a Dynamic Disk. Anyway, I did that.
 Still, no luck. When I try to create the mirrored volume on the second drive, it only allows my to mirror the small unused area of the first drive and not the main volume.
 I have not done this before in microsoft's series of OSes so I guess somewhere I am doing it wrong.
 Any suggestions?

Thanks,
---
Theo.

Unfortunately a mirrored drive must consist of two dynamic volumes--and you can't boot from a dynamic volume, because the Win2K loader doesn't recognise them! Therefore there isn't any way to mirror the 2K boot partition--all you can do with mirroring is preserve your data. You'd need a third party partition mirroring tool such as Ghost to back up your OS.

WHAT?!? Damn! Are you sure?
pj, can you please provide an authoritative URL?!?
(preferably ms)?
You are saying there is no-way to mirror my one and only partition on this server?!?


Thank you,

You cannot format the drive to do mirroring.

In order for the OS to complete the mirroring, the drive must be left unassigned (unpartitioned).

Means that after converting it to a dynamic disk, do not format it. Leave it as unpartitioned.

Then click on your C drive, hold the 'ctrl' key and click on the UNPARTITIONED DRIVE. After both drives are highlighted, right click on either one of the drive and choose Create mirror.

You should purchase an IDE RAID card. You attach both drives to this card and then in the utility, you configure the second drive to mirror the first. It's only my opinion, but I HATE software RAID.

Here is one example of an IDE RAID card. I have never used this one but Promise controllers are very good. I have only used the High-point Tech controllers manufactured by ABIT. I use the HPT-370 controller.

OK, dunno, I checked your answer and it worked!
Few days later I checked the operation of the mirror set  and it reported errors but I guess that´s a problem with the second drive being in a removable kit (something wrong with the connection maybe).
