There doesn't seem to be any drivers on the Tascam site for your T2488 so the only way to find out is to connect it and see if Windows looks for driver and finds them or if it just shows as a drive.
If it shows as a drive you can just cut and paste your files to any other drive.
Hi viv. I wouldn't bother with all that; it is very limited in its capability and somewhat cantankerous to activate. I installed a 120 gig hard drive and have plenty of real estate! That is a LOT of toonage, unless your stuff tends to run over 8-10 minutes each and all use 24 tracks. Mine's a Seagate; sorry but I don't remember the Mod.#. It doesn't seem to be too picky, either. I had a choice of 80 or 120 and both worked; I stashed the 80 in my desk for future use, but that was almost two years ago and I haven't even filled up half of the 120 gig yet! Hope this helps. Happy recording.
