A new WD30EZRX that I order arrived today, so I wasted no time trying to install it. However, when I put it in my external case, Windows seven couldn't set it up, even though Disk Management did see it. I then tried using Acronis DDS11, but it hung right after it opened. I then moved the drive to an internal location in the PC case, and though it gave me fits, I finally got it to initialize the drive using GPT, rather than MBR, so that the partition would include the entire drive. I then attempted to test the drive with HD Tune, but the benchmark failed, saying that there was a read error. Despite fact that the SMART DATA said all was well, but when I ran the quick error scan, it showed the first block on the drive as damaged. There really was not point, but I then ran a partial extended test with the same block showing up as damaged. HD Tune showed the drive as being only 2.2TBs, when would indicate that it was reading an MBR partiton, but Disk Management shows the entire 2794.39GBs in a single partiton. I contacted the vendor, requesting an RMA, but the response I received asked that I use WDC's DLG to diagnose it instead. Even though that annoyed me, I went ahead and tried it. When I tried the quick scan, it froze when the progress bar got about 3 bars from completion. I don't think there is any point, but I then started an extended scan...which will take a number of hours to complete. Regardless of what DLG says, I feel sure that the drive is a lemon, and if the vendor continues to give me problems, I shall go to WDC support instead. I really don't expect anyone to explain all of this to me, but I am confused how Disk Management and HD Tune could be seeing different sizes for the partition? Can anyone shed any light on this?
