Maxtor One Touch upgrade? Is this possible?

I have a couple Maxtor 5000’s 120 Gig one touch drives laying around. All of them have dead hard drives that are unreliable, plus the warranty is over on all of them. So I opened them up and popped in a 320 Gig drive. But XP still sees a 120 Gig drive. Do you know if you can help me out with this?

I have been reading into Flashing the rom but no one seems to explain if this will fix my woes. I am trying to avoid having to purchase a new enclosure.

Without sp2 your OS will only recognize 137GB of that hdd, and I suspect that the missing 17GB may be a combination of cache and amount being used. It might be worth downloading SIW and see what it shows.
