I have an external hard disk of Samsung 650GB which got damaged when I was transferring some files to my pc through it. Now when I connect to any PC or Laptop it shows the safely remove icon but there is no letter assigned to it and also doesn't show up in My Computer though it can be seen in Disk Management. I tried Mini Tool Partition Wizard but when I create a new partition it stops at 90%. I tried wiping out the partition but to no avail. Is there any solution for it??? Please help.
