I read all about the "issues" with the XT drives several moonths ago when I was looking to upgrade my
laptop to a 500gb HDD, because of what I read I eventually settled on a WD500BEKT drive
Later on I got another 500gb WD drive, the second drive was a WD500BPKT with the 4k sectors
As I'm running Windows7 this was not an issue, but the newer "Intel Matrix Storage Driver" was...
and that was incompatible with the driver for my Intel
Flash cache memory that was factory installed in my notebook.
On my notebook this really didn't bother me, because the BPKT drive without the flash cache
was actually the same speed as te BEKT with it.
I gave the Flash Cache Card to a friend who owns an indentical notebook,
but not an AFT WD drive
