Volume mount points enable you to surpass the 26-drive-letter limitation.
A volume mount point is a drive or volume in Windows that is mounted to a folder that uses NTFS. A mounted drive is assigned a drive path instead of a drive letter.
SnapDrive supports the creation of up to 128 LUNs. By using volume mount points, you can graft, or mount, a target partition into a folder on another physical disk. After you create a volume mount point in SnapDrive, the volume mount point drive path or label displays in Microsoft MMC Disk Management pane, as well as in SnapDrive MMC Disk List pane. For more information about volume mount points, see Microsoft article 280297 and 205524.
