If the drive was that fresh, it may have been better to search the makers site for a firmware update. I had all sorts of funkity things with these 1T seagates, went to the seagate site and found there was a firmware updater, downloaded it, it updated all 4 drives without losing a single byte, and except for one that goes read-only on the first write just recently, they all have north of 50k POH on them now. I have not done that yet for this pair of 2T's, but since they are "commodity drives", the need for a firmware update wouldn't surprise me a bit. I haven't used them enough to see if they might be having a session of hiccups yet. > "Modern hard disk drives are equipped with a small amount of spare > sectors to reallocate damaged sectors.

In my case, the second read failed miserably (“Unrecovered > read error – auto reallocate failed“)." Bad drive already if it was out of spare sectors at a year old, warranty it.
