I have Samsung HD103UJ 1TB hard disk and i use it as External. One day i transfer some file and the power shut down.. so when i open the PC again the HD doesn't show in My Computer only in Safely Remove Hardware.. i try to format it with Win Xp CD but it doesn't show too.. the only place it shows that i have plunged in the HD is in Safely Remove Hardware Icon. I have very important file in the HD and i new help to fix it or restore this files.
