Here is something from an earlier post on the -36 error that may help to identify the issue:
A -36 is a disc I/O error. You might have a corrupt file, or a corrupted drive. Try creating a new file and see if you still get the error. If you do, it might be wise to run a Disc Repair program to see if it can find any errors that it can fix.
And one from another thread:
You need to format your drive correctly. New drives come formatted for Windows, & then they seem to work — but not properly.
+Applications > Utilities > Disk Utility+
Choose one of the +Mac OS Extended+ formats.
Obviously first you will have to back-up all the data you have already put on the drive, because it will all be lost when you re-format.
Hope one of these may help!
Refurbished MBPs from Apple can be returned/exchanged within the 14 day from date of purchase period as 'new' ones. I suggest a trip to the Apple store and have the genius bar technician look at it. Make a decision then whether you want it fixed, exchanged or a refund based on that information.
