The external hard drive isn't recognized anymore. I used the SeaTools and did some disk analysis and it told me that it couldn't continue after discovering over 20 bad sectors. This external is very important and I need all or almost all of the files. Is there anything I can do to repair this hard drive? I tried going through the properties and doing an error check but it won't even start. It shows up in My Computer but it reads as 0 bytes and asks me if I want to format it if I try to open it. I really don't want to format it. Please help.
