I can't add to the advice about what to do with the drive you are working on. I have a separate thought about dealing with this problem, which is to back up and take files with you. At this point, an external 80 GIG firewire drive is under $300. (not fast enough to run Protools on, but very quick for backing up stuff). It is sad if there really is someone purposely destroying files, but backing up on a separate drive is a sort of a fact of life, and should probably be part of the service you offer a customer. You should be paid for that service for the time and cost it takes to back up, and any customer that turns down that service should assume the responsibility for the [sadly] fairly common loss of data that occurs with these wonderful but complicated-and-error-prone machines.
