The info shows you have not lost anything BUT you do have some bad spots
on the drive which have been de-allocated.
IF you have the time, you can use "Spinrite" to re-cert a drive. I did
this once with a drive that was "JUNK" and given to me from the company
I worked for. It took a week on Spinrite, but after that did not fail.
I took it out of service due to it's size years later. (SMALL) Spinrite
writes every possible combination of data BITS to every writable area,
locks out bad sectors and more. IT DOES WORK. I've used it several
times over the years.

How many [thousand] hours on the drive? I think you're gambling if
you have more than 26,000 hours (3 years) and ESPECIALLY if it's
really a Hitachi drive. Seagate bought Hitachi recently, and from
what I've seen, are selling used Hitachi drives as "new" Seagate
drives - check the model number and the run hours!
Hard drives are killing me this year - I've spent over 80 hours in
rework because of failed drives - especially with Seatachi drives (see
above). 80 hours of rework at no pay is a painful lesson.

Greetings!
I have a 500GB Seagate ST3500312CS SATA drive salvaged from a
decommissioned DVR. The DVR's OS said SMART status OK. The latest
Seatools disk utility from the Seagate website says the drive is A-OK
(short test, long test, full erase, re-test) no errors found.
However, the Gnome disk utility in Mint 17 says 'Threshold not
exceeded' and 'Disk is OK, 178 bad sectors'.
Some other SMART attributes displayed:
ID1 Read Error Rate: 152141757
ID5 Reallocated Sector Count: 178 sectors
ID187 Reported Uncorrectable Errors: 0 sectors
ID198 Uncorrectable Sector Count: 0 sectors
ID199 UDMA CRC Error Rate: 0
GSmart Control 0.8.7 is reading the same thing, 178 sectors, but also
says it's OK.
running an e2fsck from gparted reports 0 bad blocks.
I've also retested in another machine with different cables to
minimize the possibility of bogus hardware or BIOS issues, but the
results remain the same.
Seagate's website has a FAQ that says their tools should be the final
say as they're designed to work correctly with their drives.
Normally a bad sector or two wouldn't bother me, I have drives that
have been running for years like that. I just keep backups fresh and
check for bad sector growth. A few bad sectors is within spec and
that's why HDD's have a reserved area. Yet somehow 178 sectors seems
like a lot.
Should I trust this drive for anything more than a paperweight?
Should I trust anything with the words 'smart', 'affordable', or
'free' in the name? ;]
Thanks!
