Installing the HSZDisk class driver when NTFS partitions exist on the RAID
subsystem causes Windows NT to reassign the drive letters. (HSZDisk inserts
all RAID array-based partitions ahead of any local (non-shared bus) partitions.
Windows NT would, for example, reassign drive letter C from your system
disk to the first NTFS formatted storageset partition, Disk 0.)
Since drive letter reassignments by the HSZDisk class driver could invalidate
your drive mappings, you must temporarily remove NTFS drive letter
assignments for all partitions on the RAID Array prior to installing the
HSZDisk driver.
CAUTION: Do not remove the drive letters for local drives or the boot partition.
To remove drive letter assignments temporarily, follow these steps:
1. Start Disk Administrator. Figure 4−1 shows the Disk Administrator
window displaying current partitions.
