What is Bad Sector:

A bad sector is a sector on a computer's disk drive or flash memory that is either inaccessible or unwriteable due to permanent damage, such as physical damage to the disk surface (wiki pedia)

A bad sector on a hard drive is simply a tiny cluster of storage space — a sector — of the hard drive that appears to be defective. The sector won’t respond to read or write requests.


A physical — or hard — bad sector is a cluster of storage on the hard drive that’s physically damaged. The hard drive’s head may have touched that part of the hard drive and damaged it, some dust may have settled on that sector and ruined it, a solid-state drive’s flash memory cell may have worn out, or the hard drive may have had other defects or wear issues that caused the sector to become physically damaged. This type of sector cannot be repaired.

A logical — or soft — bad sector is a cluster of storage on the hard drive that appears to not be working properly. The operating system may have tried to read data on the hard drive from this sector and found that the error-correcting code (ECC) didn’t match the contents of the sector, which suggests that something is wrong. These may be marked as bad sectors, but can be repaired by overwriting the drive with zeros — or, in the old days, performing a low-level format. Windows’ Disk Check tool can also repair such bad sectors.


Causes of HARD Bad Sector
1. Factor DEFECT

2. Dust

3. HEAT

4 Physical Damage

5 Fragmenting sector ( pag nagbura ka ng large amount of file or copy ka taz di mo DEfrag ang hardisk mo,
and head po kc ng hardisk ay prang karayom... (layman term po tayo pra maintindihan nyo) turn table pamiliar po ba kayo? ung karayon ng hardisk kapag sa isang lugar lang nag sesearchor nag susulat ng data
99% n mag kakaroon k ng bad sector... kaya tandaan mag defrag pag wlang ginagawa...

anytime boss wla kc magawa, while recovering tong sa tomer na hardisk... kya napapost yan...
 
And always use UPS lalo na pag desktop, isang dahilan kasi pag biglang black out patay agad ang Pc pero pag may UPs may oras kapang mag log out. Power failure isa sa mg adahilan rin ng pagkasira ng har disk.
 
Salamat sa info boss....
Isa din pala sa dahilan ay ang overheat...

isa sa main factor ang pag init ng hardisk due to poor ventilation... common sa laptop... kya on my exp. mas madaming hdd n ntototdas kesa desktop...
 
any software used for defrag and repairing bad sector w/o the command cmd sir???

anyway salamat dito sa tricks sir...

try ko...


right click mo ung hardisk > tools > defrag or scandisk...
 
thansk sir...

finish checking 3 tera hdd...

now on defrag status...

nice....
ugaliin mo yan sir every week or ever 2 weeks... prone kc ang mga malalaking hardisk kc di nagbago ang size ng disk,,, pinaliit ng mas maliit pa sa DNA ng tao bawat sector pra lang accomodate ang sector... kc nhihirapan ang head....
 
at dagdag kuna rin don't cut and paste large amount into other hdd. in the result nadadamage yung pinag cut mo na hdd many times na nagyari sa akin kaya iwas na ako dyan sa cut and paste.
