You have to take care about the "pre-fail" values:
***
1 Raw_Read_Error_Rate 0x000f 116 099 006 Pre-fail Always - 115084648
7 Seek_Error_Rate 0x000f 067 060 030 Pre-fail Always - 17202967923
10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0
***
"Raw_Read_Error_Rate" and "Seek_Error_Rate" are very high.

Yes, I also saw these values were very high on my Segate drives and was also
alarmed, but looking into Wkipedia [1] I discovered that Segate drives just make
another interpretation of that values, so unless you are getting another smart
warning (or you hear some "clack, clack" noise coming from your drive), I would
not worry for these.
***
01 01 Read Error Rate
Indicates the rate of hardware read errors that occurred when reading
data from a disk surface. A non-zero value indicates a problem with the disk
surface, read/write heads, or the heads are not centered exactly over the track.
Note that Seagate drives often report a raw value that is very high even
on new drives, and does not thereby indicate a failure.
07 Seek Error Rate
Rate of seek errors of the magnetic heads. If there is a partial failure
in the mechanical positioning system, then seek errors will arise. Such a
failure may be due to numerous factors, such as damage to a servo, or thermal widening
of the hard disk. More seek errors indicates a worsening condition of a disk’s
surface or the mechanical subsystem, or both. Note that Seagate drives often report a
raw value that is very high, even on new drives, and this does not normally indicate a
failure.

Any information about the drive unit (model, serial number and firmware
version) should be displayed with "smartctl -a /dev/sda".
