The 3FX error code, by the "x" indicates WHICH drive is failing.  In a PC with one drive, that "X" is a ZERO -- indicating the first drive.

When it says 3F1, that indicates the second drive is failing.

Since you provided us no model number information, we have no way of determining how many drives your PC has.
