WD2500BB-55GUC0 - I don't understand what cause the problem

[Damon]

Hard drive as in topic.

Format in PC-3K runs forever and never ends, If I verify disk, it runs very good until it reaches about only 13M LBA. From this point almost every sector is (INF) "bad" and last to the end of the disk.

Heads are ok, all modules checking ok, self-test runs smoothly and also is ok...

What the hell can cause this problem?

It would be a pity to trash 250GB...

Clean both P- and G- , cycle power, regenerate translator, cycle power, run SS again.

OR there is a bad area exactly at 13M LBA that need to be isolated (cut zone) . Then it should be OK.

[Damon]

Thanks BlackST

I will try and put the results, but what is SS for You?

[Damon]

I did SS again with your hints BlackST but unsucessfully. Thanks for help, cutting zone seems no sense for me, so hdd has been trashed

[BlackST]

Why cutting zones has no sense ? it's better a "little less than 250 GB" than "0 GB trashed" drive :S

Take into account that sometimes downsized or refurbished drives are invaluable as intermediate carriers for shipping or for reviving "that" machine just-in-time. Also, it is environmentally friendly to recycle these drives !

[Damon]

Of course trashed means it will be recycling, be sure. I'm also environmental friendly as You BlackST Everyone should participate in recycling - I think that people slowly are getting used to that.

Thanks!

If heads were OK, it sounds like a translator issue. Maybe you binned this drive needlessly?

[BlackST]

he said that he followed my advice - clean defects and regen translator and SS so the translator is to be excluded.

Do a head test maybe one of the heads is bad .
