I've noticed that when those particular iBook's have a failing hard drive, it's hard to determine, because the clunks are so random, it's not as consecutive as they usually are in other hard drive's I've heard. Must be the IBM made drives of that era, I don't know.

Man, I can't remember exactly why that error happens. I used to be able to and it was all good.

Try saving the file instead of saying open with app X Y or Z. Don't remember if IE of that time had the ability or not.
