The I/O device error indicates that your system is having a problem reading the critical partition information on the drive.
If this drive was intentionally or unintentionally removed improperly from the computer, it may have caused this error.
I recommend reformatting or repartitioning the external drive if you have additional copies of the same information somewhere else and the data on the external drive is not important. This will erase all data on the external drive. However, once that is done you should be able to copy over the data back to the external drive. Please make sure the drive is safely removed from computer using safely remove icon before detaching the drive from your computer.
If the data on the external drive is important, do not format the drive. Instead you may need data recovery software to help recover the data. Here is a link to our DIY data recovery software if needed:
There are also several free versions available on the internet.
