File corruption pattern

Wed May 18 12:14:07 UTC 2005

File corruption - Fedora Core 3
shutdown -r -F now gives no errors.

Image file created on a P4 system with no problem after
earlier corruption on AMD 64 machine that was working before.

13,585,246,488 fc3ll.lzo

File copied to AMD 64 machine using ncftp no error in copy,
but then fails lzop -t <fc3ll.lzo test with checksum error.

Then copied file to another system to compare original file to
file from amd 64.

System was working fine with 4 images, but now fails, on image 
creation,
images that worked before, and even trying to blank drive with
dd if=/dev/zero of=/0bits (Machine froze after about 8.3GB)

Here is the comparision of the bad file versus good file.
Note: all addresses end with 3 and all differences are either
08 hex or 80 hex?

The system is less than 1 month old, and is an MSI 6741 
motherboard with a 250GB Maxtor Diamond Max 10 6B250R0 drive.

Other than this error, which was working earlier with 4 pervious
images, but now even those fail the lzop test.

Ran the Gyum, and it went thru the install of the new updates with 
no problem.

Any suggestions on what tests might help to find what is causing the
problem. Does it look like motherboard, harddisk, hdparm, etc.
