'PERFECT'
'Problematic or weak sectors not found'

The seek error rate means that the drive is over- or under-shooting the correct track when it moves the heads, and it has to do another (small) re-seek to acquire the track before it can read or write the data. By itself, it's going to be a performance concern, but probably not that big a concern as far as data integrity goes.

As far as data integrity, pay more attention to the "Reallocation Count", and "Pending Sector Count" values as they indicate failures to read the data from the disk itself. If those numbers are high or increasing, then you should consider the drive to be unreliable and plan to get you data off it ASAP.

How old is the drive? HDDs are made with reserve (unused) data sectors. When a drive repeatedly has problems reading a sector, it eventually marks that sector as bad and reallocates a reserve sector to take it's place. Every time it would've written data to the bad sector, it writes it to the reserve sector instead.

The number of times it has had to do this is your reallocation event count. Yours is at 30, while 99 is the threshold before when the drive reports it as a serious problem (actually, more likely this is a percentage of reserve sectors used, not an actual count). If this is an old drive (say, 5+ years old), then 30 is not unusual. But if it's a relatively new drive, then 30 is rather high and could indicate a developing problem.

less than a year old!!

See if you can return/replace it then.

It is the drive included in the laptop (Lenovo Ideapad) I bought from Newegg. I did a 30 day RMA because there was a hd problem as reported by hd SENTINAL which later corrected itself. Newegg tested the hd and found no problem. The hd is actually a little over a year old.

All my other hhd have the following reading and are WD drives:
196,Reallocation Event Count,0,200,200,OK (Always passing),000000000000,0,Enabled
197,Current Pending Sector Count,0,200,200,OK (Always passing),000000000000,0,Enabled
Some are over 5 years old.
