Err Msg: Setup Requires a Local Hard Disk That is Visible (124872)
The information in this article applies to:
- Microsoft Windows NT Server 3.5
- Microsoft Windows NT Server 3.51
This article was previously published under Q124872 SYMPTOMS
When you attempt to upgrade a computer that is running Windows NT and
using mirrored hard disk drives to a later version of Windows NT the
following error appears:
Setup requires a local Hard Drive that is visible at startup which
requires at least 36 MB of free disk space in order to upgrade
Windows NT. No such drive was found.
CAUSE
Setup determines, from the first partition ID byte on the hard disk drive,
that the disk is part of a fault tolerant disk configuration. Because
Setup does not distinguish between mirrored sets and any other type of
fault tolerant configuration, Setup stops.
MORE INFORMATION
This error also occurs on some hardware implementations mirrored set,
fault tolerant drives.
WORKAROUND
To work around this problem, break the mirrored set, install Windows NT on
the primary partition, and then reestablish the mirror.
STATUS
Microsoft has confirmed this to be a problem in Windows NT versions 3.5
and 3.51. We are researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.
