Input/output errors are most often hardware problems. After the error appears, you can use the dmesg command to see a system log with more details.
The hardware problem could be as simple as a loose cable connection, or more serious such as a failing hard drive. You might wish to use gsmartcontol to see if there are other indicators of the drive failing.
here is what appear in dmesg :

it is a 4 years old usb drive , so it could be failing (dying) ,
windows seem to think it is a read only drive , and try to give me help on read only drives .
