Method 4: Using a USB-Hub with a separate power supply
As some users have reported, the issue can occur if you’re encountering the error with an external HDD that is powered by your computer – without a separate power supply. If that’s the case, it’s very likely that the error occurs because your computer isn’t able to power the HDD over extended periods of time. Typically, if this is the reason why the error occurs, you’ll notice that the error will only occur with large files while small files will be copied just fine. If this scenario is applicable to your current situation, try to use a USB Hub that has a separate power supply, and see if it’s able to provide more power than your computer can. Note: Another possibility to consider is that your HDD is overheating when having to copy a large file. If you see the error occurring at different intervals try to lower the temperature by installing an additional case cooler or keeping your external hard drive in a colder environment.
