I bought a HD from from a shop sometime in April last year. After filling it to the brim in some three months, it stopped working (as in it no longer shows up on in windows explorer). I gave to IT professionals to recover the data, but no luck. The opened the casing to do it, which nulls the warranty.
At this point, I have given up on recovering the data. But if the HD itself is salvageable in any way, I will be truly gratefull.
