I have a Seagate 3TB Expansion Desktop drive that was part of a Linux RAID 6 array that failed.

I eventually did a zero fill both through Seagate DiscWizard and via Linux dd, neither reported errors.

When I ran Seatools now, I got:

Short DST - Started 5/31/2014 10:04:36 PM
Short DST - Pass 5/31/2014 10:05:37 PM 
Long Generic - Started 5/31/2014 10:15:19 PM
Bad LBA: 518242762     Not Repaired  
(whole bunch of bad LBAs ommited)
Bad LBA:  518715255     Not Repaired
Long Generic Aborted 6/1/2014 3:12:18 AM

i.e. the short test passed, the long test failed.

Unfortunately, the drive is out of warranty, so I can't just RMA it. But I hate tossing a drive that can still be used.

So, my questions are:

If the zero fill succeeded, and the short test passed, can I still use the whole drive?
if not, since I'm using LVM on top of RAID, is there a way to tell either of these to just skip the bad area?
If not the above, can I just create partitions before and after the part of the drive with the bad LBAs?
