I have a 2 TB HFS+-formatted external hard drive that got dropped a couple of days ago while transferring files onto a Macbook Pro. Now the drive's partitions won't mount. Disk Utility can see the drive, but doesn't recognize that it has any partitions.
I've tried using Data Rescue 2 to recover files off of it, but it couldn't find anything. In addition, our local computer repair shop said they couldn't find anything on there either.
I know that I could ship the drive off to someone like DriveSavers, but I was hoping for a cheaper option (since they start at about $500 for the attempt).
Is there something else I could try on my own? Would TestDisk be able to help with something like this?
