External Hard Drive Suddenly Not Recognized by Computer

User1: I have a 1.5TB external hard drive which has been used for about two years. Just a few days ago, I plugged in the external hard drive and then got an error message that "USB connection unsuccessful, devise not recognized". The error message disappeared after I unplugged the external hard drive and plugged it back again. However, today the same error message comes back again. No matter what I have tried, the external hard drive keeps not recognized. How can I get the data off the external hard drive?

User2: My Seagate 2TB external hard drive can’t be recognized by my computer now. The light is still on but I can’t find the drive letter on my computer. I checked the external hard drive under Disk Management, but it shows the external hard drive as unknown devices with yellow exclamation mark. Is it possible for me to recover data from the external hard drive?
