Issue For Aspire 4530 Owners on Windows 7

Please take note when installing NForce Drivers
Make sure your Add/Remove Nvidia Driver has the entries below:

Use the 15.45 NForce Drivers I advised (Can be downloaded on Guru3d.com) DO NOT USE 15.37 NForce Drivers from Nvidia except for the AHCI Storage Driver from 15.37.
Note you get SMU Driver and PCI System Management Drivers, otherwise you get a Fatal Machine Check error occasionally in Windows 7 Event Log, you won't see any BSOD but the error log will be there .
In conclusion use the Storage Drivers from 15.37 and SMU and PCI System drivers from 15.45.

Update:
Please update the Storage Driver from 15.51 (from Guru3D) the driver from 15.37 causes occasional freezing issue.

Windows 7 Boot Optimization Error

I am not sure if you guys know you can manually invoke Windows 7 defragmentation Tool to do boot optimization by using the /b flag.

When you run defrag.exe, you get the following

Microsoft Disk Defragmenter
Copyright (c) 2007 Microsoft Corp.

The parameter is incorrect. (0x80070057)

Description:

Locates and consolidates fragmented files on local volumes to
improve system performance.

Syntax:

defrag | /C | /E [/H] [/M | [/U] [/V]]
defrag | /C | /E /A [/H] [/M | [/U] [/V]]
defrag | /C | /E /X [/H] [/M | [/U] [/V]]
defrag /T [/H] [/U] [/V]

Parameters:

Value Description

/A Perform analysis on the specified volumes.

/C Perform the operation on all volumes.

/E Perform the operation on all volumes except those specified.

/H Run the operation at normal priority (default is low).

/M Run the operation on each volume in parallel in the background.

/T Track an operation already in progress on the specified volume.

/U Print the progress of the operation on the screen.

/V Print verbose output containing the fragmentation statistics.

/X Perform free space consolidation on the specified volumes.

Examples:

defrag C: /U /V
defrag C: D: /M
defrag C:\mountpoint /A /U
defrag /C /H /V

Notice there is no /B flag but it is there.
However on a fresh Windows 7 installation when you try to do this with Administrative Permission in a Command Prompt Window.

C:\Windows\system32>defrag C: /B

You get some message saying it cannot be done like the following:

Microsoft Disk Defragmenter
Copyright (c) 2007 Microsoft Corp.

Invoking boot optimization on (C:)...

Analysis: 100% complete.

Some registry entries were missing from the boot optimization section of the reg
istry. (0x89000017)

How to resolve this?
The issue is the idle tasks Windows is scheduled to run hasn't run once yet hence it cannot initialize boot optimization.
So to resolve simply open a Command Prompt Windows with Administrative Permission again and run the following commands to invoke the idle task.

C:\Windows\system32>Rundll32.exe advapi32.dll,ProcessIdleTasks
After that the error message will be gone and you can run boot optimization manually.

Why doesn't this happen sometimes?
Because RunIdle task is scheduled to run eventually after sometime of idle usage
if you do boot defrag immmediately after installation,
RunIdle task hasn't got a chance to run at all so you have to invoke it manually
if you want to start the operation immediately.

Acer Harddisk Failure

Firstly, if the Harddisk came from an integrated OEM System, the warranty is honored by the OEM.

The warranty is not going to be the responsibility of the Disk Manufacturer unless the Harddisk is bought separately in a retail store, so if you run out of warranty you will have to buy a separate harddisk replacement by yourself.

Symptoms of Harddisk Failure:

• Windows hangs while Booting or takes a unusually long time.

• Windows hangs while shutting down.
  

• BIOS hangs while booting. (To restore normal booting from a normal harddrive simply enter BIOS and set Clear NVRAM to yes, Save and exit)

• Windows Event log report S.M.A.R.T(Self-Monitoring, Analysis, and Reporting Technology) Failure. (A S.M.A.R.T Failure report definitely predicts a drive failure while not all drive failure will definitely be detected by S.M.A.R.T)

• Linux Desktop suddenly colour corrupts and doesn't respond at all.

How to resolve:

1. Boot from a Linux Live CD and copy all your important data to an external harddisk. (Do not attempt to boot from the failing harddisk, it only makes thing worse)
2. If you have a desktop and the notebook harddrive uses a SATA connector you can simply plug your notebook harddrive to a connector, boot from the desktop harddrive and copy the data off the notebook harddrive.
3. If the notebook harddrive uses a PATA connector then you need a bridge.
   
4. If the harddisk has failed totally it is impossible to retrieve any data unless you go to a specialized data retrieval centre which usually cost a bomb.
5. Do not go to those small computer shops that claims they can retrieve data, because they do not have the actually tools to do a platter swap to retrieve the data or recondition the harddisk, they are only out to cheat your money)

Yes I was unlucky enough to encounter a harddisk failure however I managed to salvage all the data I needed to a new Laptop Harddisk.
The new harddisk is considered a upgrade from WD BEVT Scorpio Blue to WD BEKT Scorpio Black.

The new harddisk spins at 7200RPM instead of 5400RPM and has a 16MB Disk Buffer instead of a 8MB disk buffer.
It also comes with a 5year warranty instead of a 3 year warranty.
The slight price difference justified the upgrade purchase.
Oh, and by the way the BEKT reports a 5.9 score in Windows Experience Index.
