Hello everybody,

I recently had my PC serviced and a fan on my graphics card was replaced due to excessive noise.

Now if there is a power failure or if I don't shut down windows properly, (eg switch), I dont get the usual blue screen with the scandisk happening on startup.

How can I get it back again? Any help would be greatly appreciated.

Cheers,

Wrexy.

WREXY,

I know it's long, but it includes all the bits you need to look for.....

SYMPTOMS
========

You may receive one of the following error messages when Windows starts:

- Windows was not properly shut down. One or more of your disk drives may
have
errors on it. Press any key to run ScanDisk on these drives...

- One or more of your disk drives may have developed bad sectors. Press any
key
to run ScanDisk with surface analysis on these drives...

CAUSE
=====

These error messages can occur if your computer was not shut down properly
or
when an error occurs on a hard disk.

RESOLUTION
==========

To resolve these errors, press any key to allow ScanDisk to perform the
necessary checks on all drives, and then choose to repair any errors found.

NOTE: To properly shut down Windows, click the Start button, click Shut
Down, and
then click Shut Down The Computer. You should not turn off the computer
while
Windows is running unless the computer has stopped responding to mouse and
keyboard input.

MORE INFORMATION
================

OSR2 includes versions of the Io.sys and Win.com files that check the Clean
Shutdown and Hard Disk Error bits in the Virtual File Allocation Table
(VFAT)
during startup. If either of these bits is turned on (that is, cleared to 0)
on
any drive present in real mode, you are prompted to run ScanDisk. If you do
not
press a key within 60 seconds, ScanDisk runs anyway.

The Clean Shutdown and Hard Disk Error bits are the two low-order bits of
the FAT
entry for cluster 1. If bit 0 is 0, it indicates an unclean shutdown; if bit
1
is 0, it indicates that a hard disk error occurred on that drive. These bits
are
turned on by VFAT; they are turned off only by ScanDisk. The Clean Shutdown
bit
is turned off upon completion of a standard run. The Hard Disk Error bit is
turned off upon completion of a surface scan (regardless of whether errors
were
repaired).

If either of these bits is on for a real-mode drive, Win.com displays the
appropriate error message. Pressing any key starts the following command:

SCANDISK.EXE /CUSTOM x: [[y:] ...]

If the Hard Disk Error bit is on for any drive, the /SURFACE switch is
included
in the command. Note that if the Clean Shutdown bits are off, but one or
more
Hard Disk Error bits is on, you receive a different error message about why
ScanDisk is being started.

If ScanDisk does not find any errors, or if you choose to fix all errors,
ScanDisk should finish and Windows 95 should continue loading. Note that the
default behavior of the /CUSTOM switch is that ScanDisk displays a summary
screen if any errors are found, but if not, ScanDisk quits silently.

If Scandisk.exe is not found, Win.com displays the following error message:

SCANDISK.EXE could not be found. You may have problems on your disks(s)
that
require repairing. Press any key to continue starting Windows...

If you quit ScanDisk early, leaving errors on the disk, or if ScanDisk is
unable
to finish, Win.com displays the following error message:

There was an error running SCANDISK.EXE, or it was canceled. You may
still
have errors on your disk(s). Press any key to continue starting
Windows...

NOTE: If ScanDisk does not reach the point where it turns the Clean Shut-
down
and Hard Disk Error bits off, ScanDisk runs again the next time your
computer
starts.

AUTOSCAN SETTINGS IN MSDOS.SYS FILE

To modify this default behavior, the following new settings have been
defined for
the [Options] section of the Msdos.sys file:

- AUTOSCAN=0

This turns the new feature off completely. The kernel does not check the
Clean
Shutdown and Hard Disk Error bits, and ScanDisk is not started.

- AUTOSCAN=1

This is the default behavior described above.

- AUTOSCAN=2

This is the same as the default behavior, but no error message is
displayed
before ScanDisk is started. ScanDisk starts with no prompt.

NOTE: You can also automate ScanDisk so that no user intervention is
required by
editing settings in the C:\Windows\Command\Scandisk.ini file and specifying
the
actions you want ScanDisk to take in Custom mode.

fast bloke

Short answer is put

Autoscan=1

in the options section of msdos.sys.
If you are doing this from dos you need to type

Attrib msdos.sys -r -s -h
Edit msdos.sys
add above line after [options]
Save and close
Attrib msdos.sys +r +s +h
