I have had exactly this many bad sectors for over a year that I am aware of. So they may have been there for quite a few years. My PC is about 7 years old.

I have only experienced a few seconds of grinding during start up recently, once.

I am awaiting a new hard drive.

I am posting this info, based on much research. I have read many articles telling of 'multiplying like rabbits' when someone is advising someone else with 7 or 8 bad sectors.

The reason I am posting this info, is to dispell the myth that even 1 bad sector is too much. Causing many to panic and spend more than they should based on the current advice out there.

Most Hard Drives come straight out of the factory with Bad Sectors. They merley mask them with coding. So when you look for them using software, they do not appear. So seeing 1 or two bad sectors is not the end of the world...unless they are virus related and 'multiplying like rabbits'.

Most will give this advice genuinely and with nothing to gain, as this is the safest advice. (Or to cause panic buying).

I am not proud of so many bad sectors, nor am I saying that you can let bad sectors accumulate to anywhere near this amount.

But, that you should not believe everything that you read. Had I checked a few years ago, I would have paniced. I would have replaced my hdd prematurely (not a word a man likes to hear) and it would have £cost$ me a hell of lot more that £3.60 (off EBay).

In my case it paid to wait for a good deal to come along and not panic buy.

So, you can take this info as you want.............
 
I must say that I agree with all of the replies.

I just wanted to address the fact that all of the results from my research seem to categorically say the same thing.

And all had the same affect on me, causing me to panic...

I just wanted to give my factual example, as an alternative view.

The article, where i found the info on most HDDS having bad sectors from the factory, is via the following wiki link:

http://en.wikipedia.org/wiki/Bad_sector

If you then scroll to the very bottom of the page and select the link:

Bad sector remapping techniques:

Again, I agree with what others have said.........
 
Installed new hard drive

I just installed a sold as 'unused' Hard drive in my pc.

Only, this Hard Drive has 8gb of files on it.

Also

In properties in shows:

8.04gb used
68.6gb free

That adds upto 76.6gb

It is supposed to have 82.3gb (as per manufacturers and sellers spec)

Any ideas why 82.3gb - 76.6gb = 5.7gb

Why can i not use 5.7gb

I am waiting for seller to reply to my e-mail, your thoughts on how I should handle this, please.......
 
Also is it possible that just having it sit in my pc as a slave is improving my performace.

My pc is still booting from old drive, but everything is so much faster. Like internet etc.
 
:)

Nice..............

I wanted to save myself coming across another article that says something totally different.

Good or bad, I will stick with the advice from OCUK.............with a little research

Used to do things the other way around and talked myself out of doing/trying things.

An overclocker in the making....
 
Everything is backed up and new hard drive is in place.

Am in the process of copying over to new.

The drive is new and is double the size of my current hard drive.

Yes, £3.60, I even managed to get a £2 refund. So, £1.60

The drive has passed manufacturers test drive tool and two complete virus scan, using two didfferent pieces of software (approx 5 hours in total).

Chkdsk reports no bad sectors.

Is there anything I am missing before I copy over etc etc

Thanks for the laugh scammy, I nearly wet myself reading your reply......... Having a bad day?
