This article was previously published under Q141793 SYMPTOMS
When you install a Compaq computer, the number of bytes recognized by Disk
Administrator may be substantially different from what is reported by the
Compaq disk utility.
For example, on a Compaq Proliant 4500, SmartScsi Controller with four 2.1
gigabytes drives, the available disk space was reported by Compaq Smart
Start as having 8 gigabytes available. However when Windows NT 3.5 was
installed, Disk Administrator reported available disk space at 6 gigabytes.
CAUSE
This occurs when the disk is improperly formatted during setup. If a Compaq
computer has not been previously formatted using the FORMAT FOR NT option,
the size of the disk reported by disk administrator may differ
significantly.
Windows NT uses a different method of calculating the disk sectors
available. For more information about this, please see the following
articles in the Microsoft Knowledge Base:

TITLE : Search Order for OLE Servers
RESOLUTION
In order for Windows NT's Disk Administrator to see the correct number of
sectors, the disk must be formatted under Compaq's EISA config utility,
under advanced options, option #4, NT 3.5 MAX Partition.
