I used Asus Transformer T100. Days ago, I tried to changed my PC to 64bit and when the system asked where should I put recovery files, I just press enter. When I check Devices and Drives, my D: got overwritten by recovery file and gone. It just show Local Disk (C) and Recovery (D). My HDD Dock (500 gb) can't be read or allocated. So I tried check with Disk Management and it show my HDD dock is removable, no media. Does this mean it cannot be recover ? If I can fix this, can someone help ? Please !
