Product defects or standard ?!

Unfortunately, I can only report negative.
After 2 proper use (ie secure whole data, make Pc Platt and data back to the computer store will) has the part given up the ghost, and my total data (including all my image files) were first caught in this black box.
When I then a PC technician let drann, he could unfortunately nothing more for me Tuen, the data were gone, and no longer be found.
That is to say that really everything is gone on the record. For me as a photographer a disaster! Fortunately, that no longer open orders were there.
