how LONG AWAIT FOR THIS? I awaited 30-min and still No move

can format drive and reuse it....?

The disk is physically damaged (and relocation area is full/exhausted), avoid re-using it.

here is what CrystalDiskInfo shows after format malfunctioning HDD 4TB... can use this disk as backup external disk...?

On 1st October your post #7 showed your Reallocated Sectors Count was 208 (decimal) and there were a further 120 uncorrectable sectors that were pending reallocation.

That has now increased to 312 (138 hex) reallocated sectors with a further 120 (78 hex) still pending reallocation. There are also 120 uncorrectable sectors (probably the same ones as are pending reallocation).

This drive has deteriorated over the past four days after just a further 29 hours of use. To force reallocation you would have to do a full format, not a quick format. Only after that will all the uncorrectable sectors be reallocated to use good ones from the pool of spares. That may give you a usable drive for a while, but it would seem to be only a matter of time before more sectors become uncorrectable and would need reallocating.

It's dying, do not trust it with any data you value.

If the drive has bad sectors its not re usable its knacked the chance of recovering data on bad block is very low

After only 207 hours of use this is surprising, but not unheard of (see 'bathtub curve' here). If the drive is still within warranty I would return it for a replacement.

Bad clusters, bad blocks, bad sectors means that you have a hardware failure that wont be fixed with a format.
Your disk is dying. You can't trust it.

I GET SAME caution

Well of course you do. All you have done is reformat the drive with a quick format.

That has not changed the fact that your drive is failing, having added another two reallocated sectors to replace two more sectors that died in the 14 hours the disk has been running since your previous CrystalDisk report.


Face facts, this drive is on its last legs and should be thrown away.

What if partition this external disk in 2 or 3 partitions???? May one partition be good... or all disk is failing? if is for recycle,... how waste disk - so nobody recover my data?

There's no way to tell from the SMART data where the bad sectors are. They could all be in a group, or spread randomly across the whole drive.

You could use a disk wipe program that will write to every sector, but that could take quite some time. CCleaner, amongst other things, can wipe the free space on a partition.

Or just undo the screws and remove the cover to expose the disk. That would make it unreadable. You could then use a hammer to damage it further, just to be sure.
