After unplugging and plugging again my 4TB Seagate external Hard Disk a message saying "You need to Format Disk in Drive G: before you can use it " ofcourse I canceled it and soon after it tells me "Data error (cyclic redundancy check)" is there a way to access back my data-- its very important and goes back to 10 years of my life...(I manage to keep some back ups) but there are still recent data on the same drive...Could anyone help me make the hard drive back operational with all the data it had??
