[GUIDE] How to unbrick a totally dead MBL

Hi, I have a non accessible drive. Blue flashing light with alternate green light flashing.

I have taken it out of the casing and accessed it via the linux reader and seen the drive partitions. I want to get all my images and music from the drive so have copied the data from the raid partition with the most data on but only seem to get a whole load of folders without the actual data im after. After doing a search in the retrieved data there doesnt seem to be anything there apart from the mass of folders.

My question is which part do i need to copy to retrieve my data before attempting to debrick it and get it working again?

if its a soft raid will I need to access it as a raid to get the fragmented data off?

thanks

Jim
