Titolo: AIUTO: scandisk al boot !!!

Ho installato il 98 su una macchina appena acquistata. L'HD è un
quantum da 20 giga partizionato in due (20% - 80%).
Il mio problema è che faccio la procedura di chiusura normale, appare
la schermata di fine sessione classica e il computer si spegne
regolarmente, ma inspiegabilmente al riavvio parte scandisk con la
notifica che il computer è stato spento in maniera irregolare !!!
E la cosa strana è che lo fa spesso, ma non sempre !!!
Aiuto !!!

E' un computer molto veloce? Se vai su 
www.windowsupdate.com
 dovresti
trovare, tra gli aggiornamenti disponibili, un certo "Windows IDE Hard
Drive Cache". Nella descrizione di questo aggiornamento si dice che su
alcuni PC recenti, a causa della loro velocità, lo spegnimento
potrebbe avvenire prima ancora che i dati contenuti in cache siano
stati completamente scritti sull'HD (o qualcosa del genere), con il
risultato che al successivo riavvio parte lo scandisk...
Puoi provare a scaricarlo e installarlo, non si sa mai.
Ciao,
  Marco.

Articolo Q273017 della MS KB:
      ScanDisk Runs Even Though Windows Shut Down Correctly
----------------------------------------------------------------------------
----
The information in this article applies to:
  a.. Microsoft Windows Millennium Edition
  b.. Microsoft Windows 98 Second Edition
----------------------------------------------------------------------------
----
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information about how to do this, view the "Restoring
the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key"
Help topic in Regedt32.exe.
SYMPTOMS
Although Windows may seem to shut down correctly, ScanDisk may run the next
time you start the computer.
CAUSE
During the shutdown process, the contents of the virtual cache are written
to the destination device. If the destination device is an Integrated Drive
Electronics (IDE) hard disk, data may be written to the hard disk's onboard
cache but not to the disk itself. When this occurs, the data is lost from
the cache when the computer turns off.
RESOLUTION
To resolve this issue, you can download the Window IDE Hard Drive Cache
package from the Microsoft Windows Update Web site at:
 
http://windowsupdate.microsoft.com
When the Windows Update page is displayed, follow these steps:
  1.. Click Product Updates to create the catalog of available updates for
your computer.
  2.. After the catalog is created, click to select the Window IDE Hard
Drive Cache Package check box.
  3.. Select any other items you want to obtain for your computer, click
Download, and then follow the instructions to complete the download process.

MORE INFORMATION
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys and
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.
If you are running Windows NT or Windows 2000, you should also update your
Emergency Repair Disk (ERD).
NOTE: For the updated Ifsmgr.vxd driver to add the necessary delay during
the shutdown process, it may be necessary to update a registry value. The
CacheWriteDelay value specifies the number of milliseconds of delay. To
modify this value:
  1.. Start Registry Editor (Regedit.exe).
  2.. Locate and click the following key in the registry:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion
  3.. On the Edit menu, point to New, and then click DWORD Value.
  4.. Type CacheWriteDelay to name the new value, and then press ENTER.
  5.. Right-click the CacheWriteDelay value, and then click Modify.
  6.. Under Base, click Decimal.
  7.. In the Value data box, type 2000, and then click OK.
  8.. Quit Registry Editor.
  9.. Shut down and restart the system. Allow it to finish running Scandisk
and wait for the Windows desktop to appear. Then, shut down and restart
again to check if Scandisk runs at startup.
