My external 3tb hdd toshiba suddenly dissappears and shows only 746 gb unallocated space.I have more than 2 tb info there and i dont wanna format it.i had it fully recognizable and working 2.7 tb( not partitioned) .I use a packard and bell extender that i use it as a usb.i even changed the bios from sata to raid and nothin.i tryed installing rapid storage technology from intel and some of them said that i didnt had the minimum requirements and others just stopped installing.i have win 7 64 bit 2 gb ram 800mhz intel dual core e 5200 2*2.5 ghz processor.anybody help me because i need those infos.
Motherboard: ECS GF7050VT-M5 1.0
Operating System: Microsoft Windows 7 x64 Pro Service Pack 1.0
Processor: Pentium® Dual-Core CPU E5200 @ 2.50GHz
Ive tried in another pc with xp installed and all the same .i have to mention that my hdd primarly had a sata connection working as an internal hdd 2.7 tb and when the pins of sata motherboard broke i passed it as an external cable with packard and bell usb and poweradapter.it worked fine until i shut down the pc and when i started normally the next day it wont show up and in disk management would show only 746 gb.
