Recently my Seagate 2TB portable drive had a problem which made me very frustrated. When I plugged it in the PC, it had a different drive letter, and when I tried to open it, it gave me an error message that reads "Drive is not accessible. The disk structure is corrupted and unreadable". I've tried it in different USB ports and on two other computers but only got the same result. What can I do to fix this error and avoid losing data?
