|This is one of hundreds of similar posts. Manufacturers of these drives hawk the huge storage potential, citing how many photos or pictures can be stored. All without mentioning that this is not a good idea.|
Litimo, as you have learned, you need to keep at least TWO copies of important files.
You could try removing the drive from the enclosure and connecting it internally using a compatible computer. Most likely the heads have crashed into the platters and are damaged but you could try.
Your laptop is not a suitable computer for this. A desktop capable of reading a hard drive type, size and file format.
You could also try using a drive fitness test from the manufacturer to see if it can see anything. The drive fitness test MAY work by booting to a CDR that you have installed the fitness test on.
Keep in mind that continuing to run the drive MAY cause further damage and make any recovery less likely.
