You might want to get a hdd diagnostic tool or even hardware monitor and see where your hdd temps is at.
When you have her pc running, open the side case and let it run, next gently touch the top of the drive.
If it seems to be abit too hot after startup in 30 minutes, I would recommend you begin a incremental backup and replace it soon.
Besides that, newegg is having a real good special for the next 3 days on hdd's, if money were not a issue I would replace my mothers 2004 WD before its too late.
