  1. My External HD won't show up in My Computer anymore.

    It does not show in device manager or disk manager to even assign a letter path to it

    I've Tried these steps and still no luck
    - restarting computer
    - refreshing content of my computer
    - un plug and re plug
    - device manager settings
    - disk manager settings

    in my device manager i see this under Disk Drives:
    ST3320620AS ATA Device (working properly)

    Disk manager errors -

    Base System Device PCI\VEN_1180&DEV_0592&SUBSYS_028A1028&REV_12\4&B4D00C5&0&32F0 The drivers for this device are not installed.
    PCI Simple Communications Controller PCI\VEN_8086&DEV_2E24&SUBSYS_028A1028&REV_03\3&11583659&0&18 The drivers for this device are not installed.

    Don't think either of these are it.
    Can it just be dead? the green lights show its on and i believe is working

    The green lights don't mean anything more than 5 volts is being supplied to the drive, but the drive can still be bad or corrupted... You must back up important data to non-volatile media like CD, DVD or Blu-Ray discs, and not rely on mechanical devices like hard disk drives or even solid state media
