Event ID 4100 :: Windows Backup

My Problem:
I was unable to back up my C drive onto my external hard drive by using the windows backup and restore system. I received the following error, and this is what was found in the Event Viewer:

Source: Windows Backup
Event ID: 4100

File backup failed because a shadow copy could not be created. The system might be low on resources. The error is: The writer experienced a transient error. If the backup process is retried, the error may not reoccur. (0x800423F3).

The Cause:
There are multiple causes for this error,


The Fix [note that this issue has several causes and several solutions]:

• Turn off the automatic backup before doing a manual update.
• Disable the back up service by typing services in the start menu and changing the "Windows Backup" service from being automatic and also stopping it.
• Delete all previous backups and shadow copies by...

My Results:
I had automatic backup disabled and cleared

Event ID 9 :: iaStorv

My Experience:
I experienced sessions of lag or pauses on my computer following this error. After looking in my event log I found 2,434 instances of this error.

Source: iaStorV
Event ID: 9

The device, \Device\Ide\iaStor0, did not respond within the timeout period.


The Cause:
It appears to be connected to Intel RAID or Philips DVDRW drives.


The Fix:
Some people recommend switching the SATA cables if you are using a desktop, but another simpler solution is to alter the registry. (and as always use caution when altering the registry)

1. Click the Start Button in Vista and type "regedit" then hit enter.
2. Click OK on the UAC prompt if enabled.
3. Navigate through the folders to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
4. Find the iaStorV folder and delete the folder within called "Parameter"
5. Find the iaStor folder and delete the folder within called "Parameter"
6. Restart your computer

My Results:
After using this fix, there are no longer random pauses or lag. There have not been any more Event 9's in my Event Log, and no adverse effects on my cd drive or in general.
