1. backup as much as you can before the drive totally dies...
2. check out ibm's website and see if you can create an RMA online (I know western digital allows this) or else call ibm's toll free # (I don't know it, but I know they have one

)
3. get an RMA # and then ship the drive off to ibm (this is assuming they do it the same way as western digital) and they'll check it over and send out a new one...
It's not hard to do, I've had to do it once, not the funnest thing in the world to do, but hey, if it was in 98, they'll give you a newer hard drive!
