I need a 2-th plate in the PC, so I did "this" buy and am - was quickly supplied by Amazon - as always. An old IDE drive I had already tried that was too loud. The "New" is super quiet, that is: My PC has been very quiet and did not become a little louder. Short uncertainty gave it during installation. Drive is recognized and listed in the Device Manager "without conflict". However, in the Explorer the drive was not available! What to do? On the website of Western Digital and because I have to look under support only very briefly. It says that Win7 fully recognizes some plates not immediately or lists in the Explorer (for whatever reason). But the manual is short and precise, so after 5 minutes application of the measures described, the plate is listed as a drive. But this small restriction is likely no fault of WD but Microsoft WIN. 7 Therefore, full marks to the board, but especially because of the "quiet" work they performed.
