That's a good call johnyb. You really have no idea how long hard drives will last when they start to act up.
I've had an 80gig IDE start makeing noises and it was dead the next day.
And about 3 months ago my 74gig raptor hard drive started making those buzzing noises off and on, but never constantly, and the drive still hasn't failed yet!
But, for sure, play it safe. You really never know.
