Hard disk bad sectors.

[sukesh1090]

guys today i ran ubuntu 11.04 live cd and checked my samsung spinpoint F3(HD 103SJ) 1 TB HDD.it is showing some bad sectors in it.gpart showed that there are about 607 bad sectors in one partition.so is it possible to recover those sectors?if yes then how?
thank you.

[Sam]

bad sectors (physical damage to platter) can't be recovered. if its under warranty, get it replaced ASAP.

reinstalling OS should remap the bad sectors and PC should run stable. still either replace or sell (if warranty expired).

i got it as a replacement for my 500GB HDD.so i guess i should have the warranty but not confirm.i got it about 3 months back.is it a very big issue?can't i use this HDD considering the problem with the HDD supply.will this process continue?means will more of the sectors get corrupted?
thanking you.
here is another pic.

Samsung HDD carries 3yr warranty i guess. then calculate yourself how much warranty remains.

i don't have personal experience regarding bad sectors but from what i have read here, bad sector will continue to increase. so better to get it RMA'd before OS becomes unstable.

I've ran a HDD with bad sector for around 2 years but sooner or later you have to RMA it - so get it done Asap

Bad Sectors (if its Physical) tends to increase over period of Time, better get it replaced!

i am using ubuntu disk utility.
the os is already unstable.i am not able to boot it in to my win 7 so,i am using ubuntu 11.04 in pendrive.i will call samsung and ask them about the warranty and who will take care of it,seagate or samsung?
thank you.
guys you know how to remap or zero write the bad sectors in ubuntu?

[topgear]

I don't think you can zero fill bad sectors but bad sector fixing utilities just mark them unusable so the OS don't use them - the best bad sectors fixing tools should be from your HDD manufacturers

[Tarun]

actually i had some what the same problem but ones the data in rewritten on the same sector after zero fill it again shows up bad sectors

[sukesh1090]

^^
I will rma it.i have warranty till sept 2014.got that error number from seatool(you guys must be knowing this rule by seagate to rma the hdd)so now i can safely rma it.how is the service of seagate?

[Tarun]

not bad it comes back to us in i guess 10 to 15 days

[sukesh1090]

k guys looks like my time is not going well.my another seagate 500GB baracuda HDD is also showing bad sectors and seatools is telling it to replace but the problem is i haven't got my first drive back and it may take around 1 month more as i have to send it to Chennai.some days before also it showed bad sectors but when i formatted it and fixed it in ubuntu it was working fine,now again it is showing bad sectors and it is increasing day by day.tried to fix it but it is not working.so i want to know why my HDD are failing?what are the reasons for it?
i get electric shock when i touch my cabby.is this could be a reason for HDD failure or i did force restart for 2 times with the restart button on cabby and three days before power of my system disconnected accidentally as the psu plug was loose and accidentally i hit the cable and system got shut down immediately.so are these could be a reason for HDD failure?bcoz i don't want to send my drives again and again for RMA.
here is a screen shot of hdtune,

[Tarun]

firstly u are getting the slight shock bcoz the plug point u are using has a open grounding or in simple word no ground. try changing ur plug point or ur spike guard/extension whatever u say. it may be cause due to it too

[sukesh1090]

but the problem is i am staying in apartment so it is difficult to correct the grounding to whole house.btw will it get corrected if i get a good spike guard and attach it to a socket which doesn't have a correct grounding facility?
thank you.

[whitestar_999]

such errors indicate failure at hardware level & i don't think things like reset/defrag/shutdown etc can cause this except maybe some data corruption.electric shock you feel is probably due to improper earthing.your hard disk total usage is 2457 hours which is not much.try WD next time & as for now try running chkdsk /r from windows boot cd/dvd to see if it helps.

[Tarun]

try changing the spike guard first secondly if can try to put the main power cord to the plug point and disconnect ur HDD just for Safety purposes and see if u are still getting the shocks

thats the the correct word thanx reminding

[whitestar_999]

even in apartments there should be a earthing option as all high rise buildings have one.have you ever called an electrician to take a look at your apartment's main power board?anyway protective earthing is simply providing a connection to earth to provide a safe path to excess electricity to safely pass through.Attach one end of a wire to the side wall(metallic) of your computer & attach the other end to a nail or something metallic and nail it in the wall.

[sukesh1090]

will try it.btw i don't think seagate is a bad company.k next time will try to buy WD.thought seagate is a reliable company.

[braindead]

Similar problem so ill post my problem here.

ive got some bad sectors on my external hard disk. out of warranty.
How do i hide or prevent the bad sectors from being visible (reallocation?) so that no data is written to it? no important stuff so i don't mind losing the data.

[topgear]

^^ if it's segate drive download seatools for windows - install it - attach the external HDD and perform a long test using seatools - wait for the test to complete - it will show you the bad sectors it has found and give you an option to fix those.

That wont work $#!+. Earthing has to provide a direct sink for excess charge.

ie, @OP

a. Take a copper wire and connect it to the earthing socket of the wall socket and pull it directly to the ground and then have a piece of conductive metal(ie, an iron rod like they use in construction, or a GI pipe) inserted about 1.5m into the earth connected to that end of the wire. Actually even lesser will do, but that is the standard.

Alternatively find the pipe that pulls water from the ground to the over head tank. Check if it is continuously metal till your house, as since many years some builders have used plastic ones too. Find the nearest point of that pipe in your house and use that as the contact point to the earth.

Simply find the earthing wire in the house mains and check if it is continuous to the ground.

Or

b. If the house is earthed properly the other wall sockets will test good letting you know if the socket to your computer is one of the few that were not earthed.

Or

c. Leave it to the electrician

And about the shut down due to your hand impacting the cable, of course that slightly pulled the wire from the sockets on the wall and the PSU and cut off the connection. Totally harmless.

thanks,doing that. maybe this is going to take some time

k guys sorry for not posting i got a new seagate 1TB HDD as a replacement and it is working fine from last 10 days.even that 500GB HDD also got replaced.actuall the current shock was not because of earthing but it was because of the power cord cable which i got with my seasonic psu.i replaced it with a another cable which i had and everything got solved.that seasonic one doesn't have the third upper big pin in its plug.there is only a hole in that place.may be that was causing the problem because if i am right that is the ground pin in that.i don;t know why seasonic missed that.
@braindead,
you can also download seatools for DOS burn it on a cd or dvd abd boot from that DVD and you can zero write that HDD completely by selecting i guess complete format(or something like that.i do't remember it) it will reallocate all the Bad sectors but if the bad sector is because of malfunctioning of the drive then again you will see bad sectors within
some time of use and only solution is buying a new one.

[topgear]

@ braindead - can't say why you are getting such long scan times bvut usually it takes only one and half hour for a 500GB HDD ( with sata connector ) - using a USB cable may take 6/8 hours but not 123459:51:48 hours !

if possible connect the HDD with the mobo directly with a sata cable / or use any other USB port - may be the app/windows is not detecting the right USB interface speed for the external HDD or use a friend's pc.

@ sukesh1090 - I think you are talking about this :



it's called CEE 7/7 plug which is completely safe to use - you have such issue because the plug you got may be faulty somehow.

[sukesh1090]

^^
yes absolutely correct.that is what i am talking about.if that third pin is not important then why it is giving me electric shocks when i connect it to the psu.thanks for the help bro.

[whitestar_999]

3rd pin is not needed because earthing is provided by side clips
Schuko - Wikipedia, the free encyclopedia

also what matters is the earthing support in the socket so even if the plug has earthing support plugging it into an unearthed/incompatible socket will provide no protection.indian sockets are designed for 3 pin earthing so plugging a CEE 7/7 into indian 3 pin socket will result in no grounding.CEE 7/7 compatible socket has earthed clips which touches the side clip on CEE 7/7 plug thus resulting in earthing.

[sukesh1090]

^^
thanks now i got it its the incompatibility between my ups socket and the plug.btw what about those plugs which usually have only two pins(which are not triangular,just flat)

I've plugged my spike guard to the wall socket and UPS is connected to the spike guard .. using 2 of these plugs and they are working OK.

devices usually comes with 2 pin power plugs ( most probably ) does not need earthing.

Schuko uses pins on the wall socket to achieve the earthing connection with the bare metal on the plug by means of contact. The other end of the cord will have three sockets(ie, the earthing socket receives the ground connection from the PSU and this needs to be sent across to the ground in the wall socket).

Some devices like chargers/ speakers shouldn't need earthing, but PSU must be earthed.
