If you suspect that you wont be able to read the original disk a 2nd time, only work with copies of your image/clone.
Always image or clone the disk you are working on and only use the clone going forward. Anything you do in such a situation could negatively effect the results of the lab. If it is clear that there is a serious mechanical or electronic defect ,often identified by problem descriptions such as: “sounds funny” or “smells funny”, ask the user to consider a data recovery lab before you start working on it yourself. Starting that computer from a Live CD is usually OK though. There may be programs or services that write to the affected drive. If the hard drive is still in the Computer/NAS it is usually in, shut that system down or do not boot it the normal way. Since some file systems write to the disk even when files are read, you should avoid mounting the disk directly or mount the disk as read only. This is because any write cloud potentially overwrite recoverable data. Even if your data recovery is just about a simple deleted file, you will want to avoid writes to the disk. If you are recovering data from RAID volumes, make sure that there are no writes to any of the disks in the volume. Make sure that there is nothing that writes to the disk from which you want to recover data. Things that should be considered before you attempt to restore the data yourself The customer wanted me to try anyway and I got a good amount of the data back. So I agreed to have a look, but made it clear that I might not be able to get anything back. I did a little digging and found out, that those LinkStations use some fairly common tools under the hood. That was not entirely unexpected to hear of a tier one support worker though. Buffalos willingness to support this problem extended to replacing bad hard disks, since all data on a failed RAID0 is considered irrecoverably lost by them. The were a lot of huge red flag warning signs that seemed to suggest a disk possibly going bad, but the the guy at the customers location that doubled as IT happily ignored those. The data on it was important, and the customer did not have any current backups. 
Recently I was confronted with a Buffalo LinkStation which had a failed RAID0.
