HD Tune Pro? Data Lifeguard Diagnostic for Windows? or any other programs?

I use HD Tune Pro to check it and found Current Penging Sector  has error data 3.

One thing is for sure, you definitely need to replace the drive.

Thanks for reply.

Is there any way to solve this problem? Or I have to replace this with my retailer?

I bought this harddisk no more than one week.

I would replace it with the retailer.  You will get a new drive that way.  Also, check the next drive to make sure there hasn’t been any “handling” issues - like customers dropping the drive on the floor.  I’ve seen customers at electronics stores do it numerous times.

Data Lifeguard is a pass-or-fail diagnostic. It will only flag a SMART attribute as “failed” if its current value is below its threshold. Other SMART diagnostics such as HD Tune, HD Sentinel, HDDScan, etc will warn you about any attribute that has an error count of any kind, whether or not it has hit the threshold. I don’t like HD Tune’s SMART report because it doesn’t show all 48-bits of each raw value. The author doesn’t appear to understand that the uppermost 16 bits sometimes have important data.

In your case you may find that a zero-fill operation may clear the “pending” sector count. A “pending” sector is one that has been determined to be unreadable. The drive then waits for the host (ie your OS) to write new data to this sector, at which time the drive then retests it. If it tests good, then it is returned to service. Otherwise, if it is confirmed to be bad, then it is replaced with spares. If this happens, you will see an increase in the raw value of the Reallocated Sector Count attribute.

I tried to format the disk and no warning in HD Tune Pro.

So should I replace it anyways?

Current Pending Sector is now zero.

Thanks for explanation.

I did a extrend test with DLG, and it found some bad sectors, then  format the whole disk in normal.

Everything now seems ok. I will check it again later.

If you cleared the pending sectors, then you’re probably okay.  But I would keep an eye on it for a while.  In any case, always keeping a backup (a duplicate) of your data is the safest thing to do.
