Hello,
Since the problem does not occur when you boot into Linux or when you
start Microsoft Windows Vista in Safe Mode it must be a software
problem of some sort. Two things to check:
1. Look in the Event Viewer (filename: EVENTVWR.MSC) for reports of
errors related the USB or SATA. One system that touches on those
two would be the Intel chipset, so perhaps looking back two weeks
and seeing if an update occurred which affected any of those?
2. Try logging into the computer using a different account than you
normally use, including a new one. If problems persist, than it
could be due to a program which is run globally by all users, as
opposed to just by your regularly-logged-in account. This may
allow you to help determine the misbehaving program.

The last couple of weeks I have had a dramatic slowdown in USB drive access
(including the SD port) on my X61t running Vista 64 (around 1.5MB/sec
transfer instead of the expected 18+MB/s on an external HD). This is not a
hardware issue, since everything is nice and snappy in Linux and also in
Windows safe mode. It is also fast when I first boot up, the slowdown
happens around 10 seconds after boot. Is anyone else experiencing this?
The only new software on this machine in that period is the usual set of
Thinkvantage and Windows updates.
I've already tried things like deleting and reinstalling the USB and IDE
drivers.
I plan to upgrade this machine to W7 soon, which might fix whatever is
happening, but I'd like to understand the problem before I do so.
TIA, David
