I have lost drives with 8 months of work, so I feel your pain.
You can go to a drive DR but that will be upwards of $1,000.
The problem is, the more you mess with the drive, the more you might destroy the data that is on it.
With my drive, even though I was ready to hand over $1,200 to get back the data, it was unrecoverable and I had to move on.
It has been over a year since I had to re-do the 6 months of work and I can tell you it will get better, but it is not fun.
Back up. Back up. Back up. Test your back up. Back up. Back up. Back up.
