Inspired by the question Crashed Hard Drive Data Retrieval which is currently concentrating on software tools and self-help methods of data rescue, I am curious what the community's experiences are with data rescue services. These are companies that attempt to deal with drives that have survived fires, floods, or other physical damage.
My one experience with a provider was positive in that they seemed like they did make a good faith attempt to get data from the drive, but they failed to get any data. They confirmed our diagnosis of a head crash, and incidentally our fervent belief in backups. They charged a moderate fee for the attempt, and we let them simply recycle the drive on failure.
So the question is this: are there any success and/or horror stories out there to share?
