I recently bought a Seagate expansion 1TB external hard drive; it have been running well for almost 3 months now, but three days ago while I was transferring some files to a flash drive everything got stuck (the transferring was at 0-bytes/second and file explorer wasn't responding),then I tried ejecting the hard dive but since it wasn't responding I couldn't so I plugged out both the flash and hard drive disks then restarted the PC..... but :( when I plugged the hard drive back in windows made that sound but the H.drive wasn't in file explorer menu as a volume.
So I went to check if disk management detected the hard drive then disk management Welcomed me with a window having title of "initialize disk" and two radio buttons having choices of "MBR" & "GPT"(I will include screenshots). I tried both one by one but it kept on showing the error "data error(cyclic redundancy check)".And when i pressed OK there was my 1TB HD unallocated, all the "new sample" menus are grayed out when I right clicked on the disk!
Any ideas on which of my stupid solutions from above could have caused this and Please is there any way to fix this I have important files I can never get again if lost now!(and also i tried to see if it works on multiple windows PC and a Linux machine but nothing)
