hard disk bad sector problem, how to solve it?

saleemasraf (5:05:18 PM): do u know howw to repair a bad sector in a hard disk
sshaks (5:05:36 PM): u hv tools
sshaks (5:05:47 PM): give a search for disc utility tools in google
saleemasraf (5:06:01 PM): i know
saleemasraf (5:06:16 PM): but nasim panja told me to format and re partition
sshaks (5:06:32 PM): hmm ..
sshaks (5:06:42 PM): i dunno .. u will lose dta that way
saleemasraf (5:06:42 PM): those utilities according 2 him only hides d bad sectors
saleemasraf (5:06:47 PM): is that true
saleemasraf (5:07:08 PM): waise maine already format and partition kar diya hai
saleemasraf (5:07:15 PM): but bad sector increased
saleemasraf (5:07:20 PM): so kya kare
saleemasraf (5:07:35 PM): u r technical in this field
sshaks (5:07:41 PM): normally not .. how the whole thing works is this way
saleemasraf (5:07:49 PM): tell me now
saleemasraf (5:07:51 PM): ok
sshaks (5:07:52 PM): u have the physical hard disc
sshaks (5:08:06 PM): on it u have sectors to which the head writes
saleemasraf (5:08:10 PM): ok
sshaks (5:08:21 PM): on top of this u have a software driver which we call the file system
sshaks (5:08:34 PM): in ur PC it will be normally FAT32
saleemasraf (5:08:42 PM): yes
sshaks (5:08:55 PM): so this s/w knows what is written to what sector .. etc etc
sshaks (5:09:22 PM): now, when there is a bad sector, either the physical hard drive has a problem writing to the sector
saleemasraf (5:09:23 PM): go on pls
sshaks (5:09:49 PM): or the file system thinks there is something written there and doesn't overwrite it , or is prevented from over writing by other software etc etc
sshaks (5:10:02 PM): so if the physical hard disc has a problem, u can't repair it
saleemasraf (5:10:04 PM): hmmm
sshaks (5:10:17 PM): but if there is a s/w problem and the file system has some issues
sshaks (5:10:42 PM): then, reformatting (telling the file system that erase all ur pointers to the data and treat the disc as new) helps
saleemasraf (5:10:54 PM): ok
sshaks (5:11:23 PM): or else running a disc utility program which tries to write to tat sector inspite of errors and then reads back to see if its fine etc helps
sshaks (5:11:34 PM): so either way, it wud solve the problem
sshaks (5:11:52 PM): 1st try the disc utility since u won't lose data that way
saleemasraf (5:12:11 PM): inmy case after formating, and re partitioning the bad sector increased from two to twelve
sshaks (5:12:19 PM): otherwsie u will hv to backup all ur data to another Hard disc or burn CDs !
saleemasraf (5:12:19 PM): lol
saleemasraf (5:12:25 PM): now what u advice
sshaks (5:12:31 PM): if it doesn't help, format !
saleemasraf (5:12:35 PM): i have already losed my data
sshaks (5:12:44 PM): hehehe
sshaks (5:12:46 PM): ok!
saleemasraf (5:12:53 PM): BIG LOL
sshaks (5:13:00 PM): so formatting didn't help
saleemasraf (5:13:01 PM): nasim panja kahan ho tum
sshaks (5:13:05 PM): then run a disc utility
saleemasraf (5:13:07 PM): nope
saleemasraf (5:13:15 PM): u know any utility
sshaks (5:13:36 PM): http://www.freebyte.com/filediskutils/
