    I recently installed a new "WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive" for additional PC storage. Used regular sata cable to motherboard & sata power cable connector to power supply unit.
    OK, so the new drive didn't appear in Computer upon 1st boot, so I went in through Disk Management to format drive,
    Did it as GPT Disk (as >2Tb) and all went to plan. Until I started transferring files onto it. Started ok (64Mb/s) but after about 30 seconds noticed transfer activity not changing. Eventually error message came up stating new file location did not exist, and the drive had disappeared from Computer.
    Restarted and back it was. But same thing happened - no matter what size file I chose to transfer.
    Reformatted disk. Same thing happened.
    Converted to MBR disk, the disk was split in two (and by the way it only let me format one of them). Tried transferring again - same deal.The last time I noticed the transfer started at 128Mb/s and slowly crept down to 27Mb/s and stayed there until the error came up. Not sure if that hadn't happen previously.
    Anyway, I fear the drive is a dud - or my initial formatting screwed with something. Or it could be connections to the motherboard/power supply?
    Will be a little bit of a work up to open her up again to check connections, so just wanted to see if any of you Uber tech-savvy Demigods could shine a light on any of this before I have to do so.
    Many thanks, Rich
