The information in this article applies to:

SYMPTOMS
========
Windows NT may fail to boot on certain portable computers, in particular Toshiba
portable computers, when the system partition is located on an NTFS partition
other than the boot partition. The following error message is displayed:
STOP 0x0000007B
Inaccessible Boot Device
CAUSE
=====
The problem occurs during shutdown when the system corrupts the last sectors
being written to disk. This appears to be a hardware problem relating to the
drive head and power shutdown, which results in an Error Correction Code (ECC)
error when reading the sector on restart.
RESOLUTION
==========
Obtain the following update or wait for the next Service Pack.
A modified Ntfs.sys driver for Windows NT and instructions for installing them
are available from Microsoft support channels or directly from the following
Internet locations:
For Windows NT 3.51:
ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT351
/hotfixes-postSP5/toshiba-fix
For Windows NT 4.0:
ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT40
/hotfixes-postSP1/toshiba-fix
The fix detects the bad sector in the restart area and uses the alternate restart
area during boot.
STATUS
======
Microsoft has confirmed this to be a problem in Windows NT versions 3.51 and
4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S.
Service Pack. For information on obtaining the service pack, query on the
