[CentOS] SSD disk and SMART errors

Two days ago I installed a brand new SSDNow E50 series (Enterprise) disk 
on a server. I intend to move the OS there. I just did the physical 
install and copied a few files to and from it just to see if it was OK. 
I left it there, waiting for an opportunity to configure it to do real work.

Now I have looked at it with smartctl -a and it gives me the following info:

   1 Raw_Read_Error_Rate     0x0033   104   104   050    Pre-fail

Just look at the number under "198 Offline_Uncorrectable". Is this 
normal for this type of disk? Is smartctl misinterpreting the disk's 
features? The disk has been there essentially doing nothing and it 
presents such enormous numbers of errors. Why?

This is under CentOS 7 (1511).
