Before you replace the drive, I'd try this:

1. First, you'll need to backup the contents of the drive to a SECOND drive (temporarily).
2. Then, re-initialize the drive using Disk Utility
3. Now, run DU's "Repair Disk" function on the [empty] drive.
4. Do you get "a good report"?
5. If you do, REPEAT the Repair Disk function FIVE TIMES in succession.
6. Do you get a good report each and every time?
7. If so, I'd restore the data and keep using it. Sometimes a drive develops directory problems that a re-initialization will clear out.

If you're still unsure, keep a SECOND COPY of the most important data stored somewhere else, as well.

its only from a cold boot once i turn the h/d off back on it remounts and all files show I've ran disutility on it and it comes back ok many times
[doublepost=1485711124][/doublepost]Its like finder is not showing the contents
Btw the thunderbolt drives with two inputs would that work with my mac mini 2012 i use display port to connect my monitor atm if i get one with teo ports can I connect the drive to the mini then monitor to the thunderbolt drive ?.
