Could really use some advice on a PowerBook problem! Unfortunately the PowerBook in question (12" G4) belongs to my mum who lives a fair distance away, so I've not been able to do any 'hands on' diagnostics. Basically she was using the machine yesterday when it randomly started emitting a high pitched squeaking/scratching sound (she described it as screaming though, bless). She called me and I asked her to turn it off - gave it a couple of minutes and asked her to try turning it on again. When she did the computer immediately started making the same noises (even before the startup 'bong' sound). Today one of her friends who is a little tech savvy took a look at it, and figured it must be the hard drive. Fortunately he was able to retrieve all of the important data from the computer whilst enduring ear-splitting screeching. 1. Does it sound like the problem really is the hard drive? It does to me, though I'm not an expert - however would hate to waste money on a replacement drive to find out that wasn't the problem in the first place. 2. Is it worth replacing the drive? Any idea how much it would cost to replace the disk? Is it something that could be done by myself, or would we need to find a specialist repair person to do it? Would it likely be more cost effective to get a new laptop? The money issue is pretty key as she's in something of a tight spot at the moment, so trying to find the cheapest solution that will get her computer working again asap. As she lives in a rural area and is housebound her laptop is very much a lifeline for her, so would be good to get it sorted. Any advice would be very much appreciated.
