could be a whole raft of things.

If you're familiar with paths (at least in Windows), it may be searching both drives in order to find things...that can slow things down some.

another thing is capacity - if your C drive is almost full, hasn't been defragmented, etc., that can cause some slowness.

If you're running really intensive programs, you could be using up all your memory. That makes the HD 'pretend' to be memory, so that will take a major hit to your program. More memory, or increasing your page size might help.

Just for an experiment, power down, remove the mybook, and try the computer. If it's still slow, it's something else. If it speeds back up to 'normal'...it's time to call those wonderful people at tech support (if they don't charge your for it)

hope that helps.
