Bad sectors - definite physical problem?


Recommended Posts

So I've been happily using my shiny 1TB Samsung SpinPoint for some three months until I found out some bad sectors yesterday. Yuck.

I did some reading about the whole thing (not like I did not run into them as much as ten years ago, but still) and still not sure whether they are definitely physically "dead" or it's fixable. I don't think it's a problem of a shock or something because noone even touched the whole PC ever since I installed it - so under that logic I'd GUESS there is a chance to fix it _somehow_. BUT I also read that modern drives have some amount of spare sectors that aren't usually used, but other sectors that are found to be unreadable or otherwise "malfunctioning" are remapped into them, and when disc runs out of there spares, then and not before scandisk or other diagnostic tools report bad sectors somewhere.

So what do you think?

Every drive has bad sectors, however, like you stated... they are excluded from the usable area before it is shipped. As long as it is not a whole bunch... you could do a low-level format (should be able to get a utility for this from the Drive manufacturer) to exclude the bad sectors from the usable area.

if there are several bad sectors, it could indicate that the drive is failing and I would suggest that you get it replaced or RMA'd (if it is still under warranty)

Well, I wouldn't dare to say discs are shipped with some already bad sectors, but.. :)

So far there is 20kB worth of bad sectors as reported by chkdsk. I am not entirely sure how many sectors does that mean, but it doesn't grow. I wouldn't normally find out at all if I didn't feel like doing a check "just for the hell of it".

This was reported by the tool provided for this disc:

Yes they are. It's mass-production and that's not perfect. If production was perfect then AMD would not sell the Phenom X3 but only the X4. The X3 is just a imperfect X4. A failure.

Every harddisk has a few errors. In the old days, when you could still do a real low-level format yourself, you had to use the "defect-list". A list of bad sectors that had to be put into the low-level format utility. Nowadays the internal logics of the drive itself take care of that.

But bad sectors that arise after production are always really bad, unless you are very sure what might have caused the problem. Like some power problem like you say. In all other cases bad sectors usually become more bad sectors.

Since your drive is only three months old there is only one thing to do. RMA it. Samsung's own diagnostic tool finds serious errors so there is no debate about that. This is a bad drive.

It's interesting the errors (I assume each of the entries stand for one sector) are right next to each other.

The real bad things are that 1) how am I supposed to backup 700GB of data and 2) the disc is installed into HDD Silencer... gah. Give me back my twelve years old PC with 2.5GB 5.25" disc :)

I only hope this SpinPoint is suitable for almost nonstop operation. I sure do like its performance.

But the bad luck floating around me is getting scary. Five boards RMAed since march and now disc...

1) how am I supposed to backup 700GB of data
1,000 CD's...

149 Single Layer DVD's...

83 Dual-Layer DVD's...

47 Single Layer HD DVD's...

24 Dual-Layer HD DVD's...

28 Single Layer Blue-ray Disks...

14 Dual-Layer Blue-ray Disk's...

...or another hard drive :unsure:

Sry, I couldn't resist :ph34r:

I personally have the same issue... I have several large drives that are all but 2% full... and need to backup data..... not fun. :wacko:

lol yup :D

The other drive thing is good idea but it's useless at the same time - I mean, buying another disc just for cases like this is um... I don't make fortune really! I need new speakers and some other things more...

Maybe over time I will buy some huge reliable disc where I will backup everything once a month.

Thats the reason I use three hard drives instead of just one big one. If I have a problem I can just transfer the data to another drive...

Anyway... I understand the money issue, but what choice do you have? Do you risk losing all your data or bite the bullet and get a new drive...

So you have 700GBs of data? Hmm, well if you are like me you could probably trim that down a bit and if that is the case why not go for a 500GB drive, they have nice western digitals going for $70 and free shipping at Newegg, http://www.newegg.com/Product/Product.aspx...N82E16822136073

Or they have a 640GB for $85... http://www.newegg.com/Product/Product.aspx...N82E16822136218

Edit: Having a second hard drive is *always* useful... As is shown in your situation... If you had a second hard drive you could backup your stuff to it :)

Edit2: I'm not much of a fan of Samsung products as almost all the ones I have owned suck... I had a Samsung hard drive 4 years ago that crapped out on me after not too long, and a DVD player that cost a good amount that doesn't work well... And I've heard of lots of issues with Samsung hard drives... But maybe thats just me ;)

Unfortunatly no... this doesn't work... I've tried it...

Gmail server ops will freeze your account after ~1.5GB (for "unusual activity") and will be inaccessable for ~3days :blink:

There are some REALLY funky ideas out there :P

Google some articles about the new (well not too new anymore, few months) SpinPoint disc with 334GB per platter. It rocks performance-wise. And aside from my bad luck I haven't heard about a person with failed one.

P.S. 700GB is AFTER deleting all the stuff I can live without :)

Not surprising.... But since you pointed that out... I'm betting that divshare.com would figure out that you have 140 accounts and lock you out.. lol

700GB of stuff huh? Sheesh, what have you got... I suppose I have quite a bit too though... I like to backup my computers games to the computer in case the CDs break... At least I used to, now I don't like doing that because it is so time and space consuming...

My wife is a photographer so we have 150GBs of pictures and thats with backing up the pictures on a DVD and deleting them after a job (well, several months after a job)...
