Err hmm .. my testing method is not the norm benchmark but is more to detect any hard defect form after the experiment..

Destructive and non-destructive testing are widely used ... I wonder what are you doing to it

It wasn't until this article that I could convince my friend that verticle mounting of hard drives is OK (he wouldn't believe me).

DESTRUCTIVE.. going to peel off the kidney sticker and feed in some smoke. Then see what the drive logs. What kind of failure seen, how it try to heal/repair the problem.. u know elementary stuff like tat ..

ancient hard drive might not be able to be verticle mount but magnet nowadays (voice coil) is so strong won't be affected by gravity. If you happen to have a bad drive, open it up, then take out the 2 piece of magnet, put them back together, is quiet hard to take them apart again using bare hand.

We have just updated the article!

This guide was written in response to the numerous fallacies about the hard disk that are still being propagated in many forum discussions. Although many articles have covered these topics, it is apparent that hard disk urban legends are still more popular than the simple truth.

So, let's get down to basics and examine some of these common fallacies or myths and debunk them!

Here's a quote from the article :-

Quote:

"To be honest, many articles have covered these topics. It would have been easy for someone to do a quick search online before imparting their opinions to newbies. Unfortunately, it became apparent to us that some folks just prefer to trust their innate instincts over logic and knowledge. As such, these hard drive urban legends have remained more popular than the simple truth (ie. "If your hard drive dies, freeze it and it will buy you enough time to retrieve its data."). So, let's get down to basics and examine some of these common fallacies or myths and debunk them!"

Formatting may damage hard disks after all(I think so). 5 years before I had a 80 GB Samsung harddisk which I used to format after every 20 days and it was damaged after 3 years only with bad sectors....
Now I am having a 160 gb Baracuda hard disk . Due to some reasons I had to format it over 20 times within 16 hours . And now I think the hard disk is working slower than it did before(data transfer).A FRIEND OF MINE TOLD ME THAT IT MIGHT HAVE GONE SLOWER DUE TO EXCESS FORMATTING WHICH HAD DAMAGED IT TO SOME EXTENT

By the way can anybody tell that what are the possible causes of bad sectors formation on hard disks

Formatting on Windows/DOS is just writing zeros to drive. Full format would write the whole drive zero. Quick format would just writing zero in the beginning of sectors. Extensive formatting would only be equivalent to normal usage wear and tear of the drive..

Yeah, formatting will not cause the hard drive to develop bad sectors. Neither will it slow down your hard drive.

Keiichi · 8th Sep 2008, 11:40 PM

And what are the possible causes of bad sector formation?
