HDD help: SMART saying i have 8 offline uncorrectable sectors.

[tatsuya1221]

When i check my seagate 3.0tb ST3000DM001 in speedfan and HDDscan, i get 8 uncorrectable offline sectors and 8 pending sectors, it tells me that i should do a read/write surface scan to remap the sector, i am a complete dunce when it comes to HDD's, so i not only don't know how to do a read/write surface scan, much less what programs i need to do so.

I'm also getting a Power On Hours Count of 88 (89-100 is what smart says is normal), and i have no clue what that means.

Sorry for being a fool, but i have no clue what to do, and it is worrying me.

Any help is appreciated.

Keep a track of it and if more sectors start going bad, you probably should save all your data and RMA the drive or get another one. I think power on hrs is how many hrs that you drive has been powered up. Not for sure about that one.

Hi,
I believe it's asking you to do a FULL FORMAT of the drive which includes rebuilding the "bad sector table".

It would read and write to every part of the drive and make a note in the BST of any areas it has issues with and then just NOT write to those in the future.

Unfortunately you'd have to MOVE your data to another drive before starting that (you can google for how to do a Full Format but it's simple).

Full format:
1. Move data to a different drive
2. Right-click drive in Windows Explorer and choose "Format"
3. Choose "Full Format" (NTFS)
4. Wait many hours (12+ ?)
5. Run Seagate diagnostic utility (long time)
6. Move data back if okay

Oddly enough after doing a read test in HDDscan, smart no longer shows the issue, should i be worried?

This is exactly what HDD status said when i checked it the first time:

BLOCKING ISSUE : your hard disk has 8 pending sectors. Those are sectors that couldn't be properly read and that the hard disk logic is waiting for a write operation to try to remap to a spare sector (if available). According to the Reallocated Sector Count attribute, your hard disk seems to have available spare sectors. A simple disk surface scan won't be enough to force the remap operation. You need a read/write surface scan to remap the sector. The best option should be a tool that knows about what should be read from that sector so that it has some option to apply the best fix to the missing data.

BLOCKING ISSUE : your hard disk has 8 offline uncorrectable sectors. Those are sectors that an offline scanning found as unreadable. Offline scanning is a process that can be automatically started by the hard disk logic when a long enough idle period is detected or that can be forced by some tool. Those unreadable sectors are identified and the hard disk logic is waiting for a write command that will overwrite them to try to remap them to spare sectors (if available).

I should point out i've never had an issue with the drive, so it came out of nowhere.
