Well, the usbmon output was complete, but it didn't show anything unexpected. Errors occurred every few seconds, and each one triggered a reset followed by a successful retry. The log contained only read commands, no writes. It's possible that these errors are caused by hardware problems in the computer's USB controller. The manufacturer's drivers would be able to work around these problems, but the Linux drivers wouldn't. However that's just a guess. And it's not clear how such errors would cause the drive to corrupt anything. The large number of errors does indicate a serious problem somewhere. Have you tried using the drive with a different brand of computer? Or a different USB cable?
