thanks. ive tried teracopy and it's not any faster.

incidentaly. i've noticed (and remembered that it has happened a few times actually). that now when im loading into the desktop at times (presumably after problems copying where explorer transfer dialogues and explorer windows stops responding and i've had to try and restart (but then it doesn't so i have to reset)) loading up is slow and the cursor is jittery, desktop icons take a long time to appear, etc - i could probably leave it 30 mins before it's fully loaded!

im guessing this is due to transfer problems mentioned above and something has perhaps corrupted on my system drive leading me to have to run diskchecks to rectify.
