Very good product, but ... 8

Strengths:
1 / capacity: 931 GB real, no complaints;
2 / transfer (very fast)
3 / no necessary formatting, immediately recognized by the computer (XP and Windows 7)
4 / remarkable silence
Weak points:
1 / the most important: comes with US plug, without adapter !!! Fortunately, I had one at home; but beware, this can be a very unpleasant surprise.
2 / No on / off switch: to put the HDD off, disconnect it, and easily one can forget to do so, given the lack of noise it makes.
3 / The case is not very solid: USB sockets & toatlement diet are not in front of their slots, and we see that the disk is held firmly inside the box.
Conclusion: good product, especially for the price; but taken inadequate, and reliability, you will see (the case of my previous WD external HDD dropped me after one year).
