I know it is an old thread but, I have the same problem with the replacement I recieved. This time the drive lasted less than 4 months.
In one of my previous posts I wrote:
I tend to believe that something is loose inside it and every time I push/pull it to insert/remove it, its behavior changes. It is usually recognised as removable disk E:, the blue light is steady on and I get the message "Insert a disk in drive E:" when I try to access it. Sometimes it is not recognized at all (the blue light is off). Sometimes it works correctly. It is recognized as CORSAIR (E:), that is the volume name I gave to it, and the blue light blinks as autoplay works.
Now I am almost sure about that. Every time it fails to be recognised correctly, I remove it, I bend it a little, I reinsert it and then it works. I do not know how many times this trick will work, but I was able to take a backup.
I know that I can ask for a replacement and I know that I can ask from your customer service to take care the shipping cost, but what is the point if the new one has the same problem? It is not only the fuss for the RMA procedure, but the risk of losing data in the future.
So I want to ask if this is a known problem and if anything has changed to the design of the product to be solved.
