Tutorial repair harddisk bad sector

harddisk depositor media of vital importance in computer. unfortunately age
limited use. damage in harddisk can be caused several things. for example:
· power supply not memadai and botch kontroller harddisk and motor.
· harddisk fallen down and botch mechanical mendalamnya or minimal happen bad sector.
· excessively brought to bring without password makes platter harddisk broken because
superlative shake.
· temperature insides harddisk hot make condition harddisk in environment not
stable.
· mtbf/age condition harddisk, reached and will broken.
matter that admit of done to repair harddisk that hitted bad sector
only where harddisk still rolling, conditon controller harddisk still to work.
but this conditon stills divided again, when want menguna harddisk that hitted bad sector.
cause problem bad sector one of [the] damage often happen. condition
damage by bad sector discriminated by 3 conditons.
· where platter harddisk worn-out. in this condition harddisk really not
can be used. longer harddisk more broken and out of use to
worn as media storage.
· condition platter worn-out but not yet achieve critical condition. this condition can be said
enough stable to harddisk. possibility harddisk admit of repaired because platter
still may be melow level.
· condition platter worn-out, good mortally condition or light but damage found
at cluster 0 (where is information partisi harddisk keep)ed. this condition not
make possible harddisk repaired.
talk about conditon harddisk to repaired only make possible repair in condition
to 2, where is surface harddisk still stable but found light damage at several
place.
aim
· efforts to menguna harddisk found bad sector
· men-eliminasi damage location in bad sector.
stage 1
before do stage furthermore best menguna stage 1 to ascertain
condition platter harddisk that broken. to detect this matter harddisk must be done low
level format (llf). llf can be done from bios or software. to bios, several pc
long like generation 486 or pentium (586) has option llf. or can menguna
software llf. to get software llf can be taken at site maker harddisk. or
look for utiliti file likes hddutil. exe (from maxtor - maxllf. exe) and wipe. exe version 1.0c
05/02/96.
function from software llf wipe off entire good informations partisi, data insides harddisk
with information bad sector. this software also good for repair maker error
partisi in fat 32 from windows fdisk.
after run program llf, so harddisk genuinely clean will like condition
first time used.
warning: use llf software will wipe off entire datas insides harddisk
stage 2
process furthermore with method try and error. stage for this session:
a. make partisi harddisk: with program fdisk with 1 partisi, good primary or
extended partisi. to primary can be done with single harddisk, but when wish for
harddisk as extended, need a harddisk as process boot and has
primary partisi (partisi to melak u booting).
b. format harddisk: with format c: /c. command increasing /c to run
when happen bad sector investigation choice. during format process investigates in percentage
what does damage harddisk. this matter is seen in picture under this.
when does format program display trying to recover allocation unit xxxxxx, mean program
is investigating where harddisk happening bad sector condition. assumption in testing
under this with harddisk seagate 1.2 gb with 2 little damage locations and
percentage number estimate is demoed by format program:
condition
menyplay in
format program
percentage
can be used
good 0-20% 20%
bad sector 21% throwed away
good 22-89% 67%
bad sector 91% throwed away
good 91-100% 9%
c. make partisi return: with fdisk, throw away entire partisi insides harddisk previous, and
make to return partisi appropriate damage note that. assumption in picture under
maker partisi with primary and extended partisi. in primary partisi is not seen and
only demoed partisi extended. distribution in picture under this in drive d and
f (22mb and 12 mb) throwed away because found bad sector. while in e and g (758mb
and 81mb) as drive that still in a condition good and can be used.
when do you enough persist to repair bad sector you, can also be done with tryerror
with repeating location livelihood bad sector in harddisk according to stage more
little, for example makes many partisi to decry possibility buangnya space
in partisi that be throwed away. more persist to look for damage in whose place
happen bad sector more gooder, only this manner will need longer time although
the result really well enough with decry where is damage harddisk
happen.
d. to ascertain to what bad sector lay in partisi harddisk that be throwed away,
do format in entire letter drive by order of format /c. when bad sector really
found in partisi that throwed away (assumption in testing bad sector lay in letter drive
d and f), so partisi can direct be throwed away. but when happen error, for example
damage bad sector not insides partisi that be throwed away but found in partisi
be used, you must repeating to return process from beginning with throw away
partisi where found error in divide partisi that hitted bad sector. matter
important to remember: maker partisi done from beginning to end, for example c, d, e and furthermore.
to throw away partisi menguna manner on the contrary that is from z to c. error in
throw away and will make partisi random aca will confuse system partisi harddisk.
e. process furthermore throw away partisi is not used again. having taken ste
investigation with format program, so in process furthermore throw away
partisi that contain bad sector. in picture under this: stage throws away 2
partisi with fdisk to letter drive d and e. to e and g partisi letter drive
be used.
f. by the end of your stage can investigate to return partisi harddisk with option 4 (menyplay
partitisi) in program fdisk, example in picture under this remained 3 drive: c
as primary partisi (is not see)ed, 2 extended partisi that still good and partisi
contain bad sector wiped off.
g. end process. you have harddisk with condition that repaired because bad sector.
letter drive divided on c as primary partisi and used as boot, d (758mb) and e
(81mb) partisi to 2 and to 3 in extended partisi.
when do you not yet satisfied with result look for bad sector, so you can repeating prosesur
on. to do tips this best detect procedure in mem make partisi
with program fdisk.
necessary registerred in tip this, careful in program use llf. best
menguna single drive to menguna this program. error does low level
format in harddisk very fatal and can not mengembalikin like condition at first.
to harddisk that hitted bad sector best menguna harddisk the condition
not yet too mortally or bad sector found at several places and not sporadic widespread.
damage in many places (sporadic bad sector) in harddisk menyulit livelihood
where happen bad sector place.
