I had exactly this problem with a USB HDD formatted with xfs. The USB cable that it came with was rubbish... the drive would disconnect & reconnect on its own for no apparent reason, and corruption happened of course. I replaced it with another cable and it worked fine after that. A few months later the power supply started to fail, it would occasionally not provide enough power and the drive would go offline or start beeping/clicking. At first I thought the disk was bad (clicking is never good) but it was actually the sound of the drive trying to spin up and failing. Eventually the power brick couldn't even spin up the drive at all. I replaced the power supply and now the drive works fine again, for now...
