If your dynamic volume is FAT16, forget it.

If you used the Disk Management snap-in to delete the dynamic volume, and you have NOT created and formatted a new volume to take its' place, you may be able to recover it.

When Disk Management removes a volume from a dynamic disk, it removes the boot sector and removes the volume from its' database. It does not destroy any data.

If the volume was NTFS:

1. Create the exact same sized volume, but do NOT format it. Remember that the Disk Management snap-in tends to round partition sizes.

2. Use the Dskprobe.exe utility, from the Windows 2000 Support Tools, to locate the backup boot sector at the end of the volume (Tools / Search Sectors) and recover it. You may find it easier to use Dmdiag.exe to locate it. See Q153973.

3. After you rewrite the boot sector, exit Dskprobe and use Disk Management / Action / Rescan. Your volume should be mounted and usable.

If your volume was FAT32:

1. Create the exact same sized volume, but do NOT format it. Remember that the Disk Management snap-in tends to round partition sizes.

2. Use the Dskprobe.exe utility, from the Windows 2000 Support Tools, to recover the backup boot sector from sector-6 and write it to sector-0. See Q247575.

3. After you rewrite the boot sector, exit Dskprobe and use Disk Management / Action / Rescan. Your volume should be mounted and usable.
