Given that liveCD works, I think I'd spend the <$100 and get a USB backup disk. Then I'd write a script to find and appropriately save image files (and maybe later some of other types). Hardware seems to be OK, so it's likely some bug / corruption in Windows. For what it's worth, I have a program (Perl) rmaiib.pl (Remove from A if in B). It can be run as follows: rmaiib.pl /media/myusbdisk1/mypath1/ /media/mydisk2/mypath2/ /media/myusbdisk1/temp/ The last element here is the "trashbin". Putting it on the same drive as the files to be removed saves a lot of time. This program does a byte by byte check and removes files that are the same, even if named differently. I use this a lot to clean up disks or directories. JN On 07/28/2012 02:55 PM, Bruce Miller wrote: > Please forgive the elementary nature of these questions.

I am being careful therefore to limit anything I do to non-destructive testing that does not touch the hard disks until I have time to do an exhaustive search for all his image files and ensure that there are *_multiple_* backups of each.

But my mind has gone blank on how to stress-test the hardware without writing to any hard disks.

The latter will put some load on the CPU and more on the graphics subsystem. Google did lead me to a sourceforge utility called systester which at least tests the CPU by attempting to calculate pi to many millions of significant digits.

The sourceforge site provides precompiled generic binaries for both i686 and amd64, both CLI and qt-based GUI versions. I have tried copying the binaries to /usr/local/bin/, chowning the binaries to root: and running as root. But, running off the Kubuntu LiveCD, I get consistent "permission denied" errors. BTW, the LiveCD drops straight to a root prompt when one enters "sudo -s" into a terminal session. There is no password. > > The system is an Intel i7 with 8GB of RAM. It is a 2008-vintage Asus P6T motherboard; the catch is that it takes an LGA1366 CPU, which is no longer available. Replacing both the motherboard and CPU will cost north of $500 and my reluctance to recommend that my friend spend that sort of money is heightened by the last 18 hours of evidence that the problem is not with the MB. > > The following is the output of lspci.
