I have upgraded by boot volume in Windows 2000 from basic to dynamic.  I want to mirror the drive.

Windows unmounted the drive and did a restart.  Now windows will not start and I get a stop error.

Is there some way I can reverse the process or is there a third party program that can fix the problem?

I have loaded Windows 2000 Server on a spare hard drive and booted the compauter with the original drive as drive 1.  When I look at the bad drive in Computer Management is says the disk is Dynamic Unreadable.  Whe I right clisk the options are
Revert to Basic Disk
Properties

I am afraid that reverting to basic may only cause more problems

While converting a basic disk, that contains your Windows 2000 boot partition, to dynamic disk, you receive:

STOP 0x0000007B Inaccessible boot device.

The basic disk contains an unsupported partition type, like an OEM diagnostic or configuration partition.

Windows 2000 supports the following basic disk partition types:

   Value   File system
  --------------------------------------------------------------------
  0x01    MS-DOS 12 bit FAT
  0x04    MS-DOS 16 Bit FAT
  0x05    Extended partition (holds logical drives)(LDM leaves intact)
  0x06    BIGDOS File Allocation Table (FAT)
  0x07    Installable File System (IFS), for example, HPFS and NTFS
  0x0B    Primary  Fat32 Partitions up to 2047 GB
  0x0C    Same as 0x0B, uses Logical Block Address Int 0x13 extensions
  0x0E    Same as 0x06, uses Logical Block Address Int 0x13 extensions
  0x0F    Same as 0x05, uses Logical Block Address Int 0x13 extensions
  0x12    Compaq EISA Utilities partition. (LDM leaves intact)
  0x84    Used by various manufacturers (Dell suspend to disk partition)
  0x86    Windows NT 4.0 fault tolerant partition indicator (FAT-FT)
  0x87    Windows NT 4.0 fault tolerant partition indicator (NTFS-FT)
Before you convert a basic disk, you must use Disk Management to remove the unsupported partition. This may alter the ARC path.

The disk is a new SCSI disk from IBM so it may have a OEM partition on it. I didn't check.  Can I 'safely' revert my disk back to dynamic?

here is the full message form the newsgroup

Hello,

As a last resort you may want to try our tool DiskPatch. Several people who
faced the same situation as you used DiskPatch to 'recover' their partitions
as Basic partitions again. This way they were able to access those
partitions again.

Once that's done, back up the partition tables with DiskPatch, this will
allow you to undo a (bad) upgrade to Dynamic.

Once you have sucessfuly upgraded, DiskPatch can be used to back up the new
situation (MBR + LDM database).

Backups made with DiskPatch of MBR, partition tables and the LDM database do
not require you to keep a backup diskette for one specific PC. Instead, any
diskette containing DiskPatch can restore backups on any machine.

Kind regards,
Joep
