Jessica has been in the workshop at work for the last two days running the manufacturer's disk diagnostic program, which reported that the disk was in perfect working order. Of course, the manufacturer's version of perfect working order doesn't necessarily mean that you can read it. Good news is that all the data on her hard drive is okay. This is most likely because it was backed up in any case and therefore could have been restored. Had it not been backed up it would have been a total loss I'm sure. Gadget has put some more memory in it and expanded the disk capacity to 160 GB. We're now running the Windows XP repair utility to see if it can be made bootable again.
