Hi, This can be caused by either hardware failure of the drive itself, or corrupted formatting that causes bad sectors on the drive. In the first case, you are usually out of luck and cannot recover data, other than bits and pieces. In the second case, do as they say. Get yourself a second drive of similar or larger size, and copy the data from the offending device to the new one. This needs to be done in a timely manner, otherwise the problem tends to get worse and you risk losing all the data on the drive. If it is the latter of the two problems, you'll be able to reformat the drive and use it again without residual issues.
