New Hard Drive Shutting Down

Just purchased a new WD hard drive for a secondary data drive. Loaded it into my pc, formatted it. It shows up fine and appears to be healthy. However, every time I try to transfer a lot of data to it, after about 5 minutes of transfer it will disappear like it isnt hooked up to the computer. Doesn't show up in device manager or anything. The only way to have it show up again is to either restart the computer or put it to sleep and upon waking up it will be detected and show up again.

The drive is not over heating, usually hovers around 34*C. It is like it shuts down when it is worked at all.

If anyone has any suggestions as to why this is happening, that would be great. Thanks a lot.

  1. Drive may be damaged. But you may try to switch off sleep/hibernate/power savings options for that drive - it's somewhere in the Power... options in control panel /for Windows/.
    Also - is it internal or external disk and with what interface /etc./? And what OS??? :O
  2. Sorry!

    - Internal
    - Sata 3
    - Windows 7 64-bit
    - Board: GIGABYTE GA-870A-UD3
    - Drive: Western Digital Caviar Black WD1502FAEX 1.5TB
  3. Yep, try switching off these features. But this behavior is shown by drives with some damage in the file system /NTFS/. It may not be physical damage and may not be detected by SMART. And unfortunately checkdisk may make things worst. ASAP make a copy of every important data from this drive and after that run some diagnostics /file system checking/. Better - copy everything to another drive and reformat /and even repartition the drive/.

    P.S. Although NTFS is considered very safe usually such file system problems /wrong file indexes etc./ actually happen after few years of using a partition as system where windows swap turns it to a mess. So - as a general precaution I ever recommend /contrary to what Windows does by default/ - never store your important data on the system partition and never in folders provided by Windows as secured folders for personal info / like "Users" and "Documents and Settings"/ because they are additionally protected from access from other profiles/OS-es and if your windows goes down they may turn out to be locked.
