I removed the 3rd party (diskeeper) to get it out of the equation.
Microsoft's defrag also causes the hard drive to stop responding and the
system to eventually lock up. (No BSOD since it just locks up and cant tell
windows about the error code, Vista just knows that it wasnt shutdown
properly.)
If I remove the new Intel Turbo Memory v1.7.0.1029 drivers (found at
http://www.intel.com/support/chipsets/itm/index.htm) completely and dont
install anything then I can defrag and no system crashes. I'm now almost
100% convinced this has to do with the Intel drivers and maybe the Intel
Turbo memory controller.
This is on a ThinkPad T61 laptop. Not sure if that provides any additional
help. Whats also noteworthy is when Vista starts up sometimes the computer
will just hang on the startup progress bar and I'll have to forecibly turn it
off then back on again. Repeatedly sometimes, but eventually it would boot.
Very randomly, about three times a week. Again, no Turbo Memory drivers, no
issues.
Now the turbo memory drivers also install the latest AHCI drivers, so they
could have some play in this also, but I doubt it.
Thanks,
Bradley
