[TIPS] How To Prevent Bad Sectors In Hard Disks

1. Do not bump your hard disk at all. The HDD may be mostly made of

metal but you have to handle them like eggs;

2. If you dont want bad sectors, never move your PC while it is on.

Never. Shutdown. Shutoff. Move the PC. Then turn it on.

3. Do not put anything on top of your HDD. If your gonna store it, make

sure they are in proper packaging (anti-static bags and clamshells o

styro boxes).

4. Only hold or handle your HDDs by their edges, never touch the printed

circuit boards or electronic parts.

5. If you have to put the HDD down on, lay it down on an anti-static bag

6. When mounting HDDs use the proper screws (coarse thread and

shorter screw) as opposed to the screws for CDROM drives and Floppy

Drives which are fine thread, and the case screws which are coarse

thread but longer.

7. Use as many screws to mount your HDD as possible, usually 4, some

techs will use only 3, I have seen HDDs mounted using only 1 screw.

Why? The 4 screws will ensure proper heat transfer from the HDD to

the case and will handle the vibration properly.

8. Tighten but not over tighten the screws. Your screws are steel, the

HDD case is aluminum, you endanger or damaging the thread in you

HDD if you over tighten.

9. You may mount the HDD in any way (level, un-level, upwards,

downwards, vertical) whatever it takes to make it fit your casing. There

will be no problem performance-wise.

But keep in mind, in the, future say 2 years, you have to unmount and

reinstall the HDD in a configuration different to what it has been

accustomed to, the HDD might die on you just like that. Example ?

vertically mounted for 2 years, then i-reinstall mo horizontally. Probably

on the startup, your hdd possibly die. It happened to me 3X already.

Perfectly working HDD, then remounted in a different way, then my

hard disk just gave up . Most probably the bearings have gotten used

to the old mounting and seize up when mounted differently.

10. Keep your HDDs cool. Blow fans on them, use coolers. At the very

least make sure your casing is properly ventilated. Heat shortens the

life of HDDs. But Choose carefully on what fans you will use, choose

the fan which produce less vibration.

11. Cables? Make sure your cables are good and connected correctly. It

may cause damage to the HDD

12. Power Supply? Make sure your power supply is up to snuff. This is

where most HDDs fail after serving you for a long time. Low 12-volt

rails kill HDD motors. Bad 5V kill HDD electronics.

13. Power connectors. Make sure your power connectors (those white

plugs with yellow, black and red wires) fit well. Loose connectors

provide bad power. After running your PC for a while, say 15-30

minutes, touch your connectors, if they are hot, then there?s

something loose, replace with a spare connector and label the bad

connector. If you do system checkups, it is good to take note of heat

discoloration on power connectors and replace those bad ones;

14. Black outs do not just kill lights, they kill HDDs. Black outs are

sometimes accompanied by bad power spikes and deadly voltage

fluctuations. If you can afford a good UPS, buy one.

15. When transferring HDDs between systems dont just take one and

install into another and fire it up just like that. Please make sure you

get into BIOS first and make sure that your new system is set to auto.

If your old system detected the HDD using manual or non-standard

parameters, then duplicate the parameters first in BIOS in the new

system before booting up. You might scramble all your data if you

new system tries to read the HDD using wrong parameters.

16. If you use your PC a lot, defrag your partitions once a month. If not,

defrag once every 3 months will be fine. For those of you who think

that defragmention speeds up your HDDs death, may I give a small

explanation. If your partition is quite fragmented, your HDD will be

doing a lot of unnecessary work by default, its head going back and

forth trying to get to the different parts of your files scattered all ove

your disk. Besides with a defragmented disk, you will have a more

responsive PC.

17. Install enough RAM. You dont want your HDD swapping files back and

forth from system RAM and the swap file. Lots of work for the HDD,

slow PC.

18. Partition your HDD. At least 2 partitions. One partition for you

Operating System. The other one for your data. This way if your OS

gets corrupted (and it happens) you dont have to perform PC

acrobatics to get your data back. You can reformat your OS partition

and be assured that your data is safe in a separate partition.

(In case your hard disk had a bad sector, use HDD Regenerator by dposoft. It Can Recover Damaged Sectors. I prefer it than Spinrite.)
