I installed Win2k on Disk0. Install done, booted machine, started Disk Management, and upgraded Disk0 from basic to dynamic. Now I cannot create a mirror (with Disk1) because Disk0 started out as a basic disk! How do I create a dynamic disk prior toinstallation so I can mirror the drive where Win2k is installed?! I must be missing something.

You can not create a dynamic disk during the installation.

Did you upgrade your second disk to dynamic?

It should allow you to mirror your first disk if both disks are dynamic.

You cannot however extend the partition that you installed to.
good luck

Some other clues for you.

1. Are Both disks from the same Manuufacturer, the same size and type?

If not 2K may complain. If the secondary disk has just One (1)/UNO sector shy of the primary, the system will refuse to mirror.

2. Is the second disk also dynamic, (I think the first poster asked this question, if so I apologize for repeating)

3. Leave some space at the end of each drive. This will allow for some differences in the drive space on each drive.

Just in case this is critical information that you are wanting to mirror and not just a play server. I would strongly suggest using a hardware based solution for RAID rather than software based. (ie. PERC cards offer this, albeit they are pricey but worth the avoidance of headaches....Needs SCSI though)

You will always have to start out as a Basic Disc unless you are upgrading from NT4 that has RAID employed. Then it will automatically convert the disks to dynamic and keep the RAID intact.

Good Luck
