发帖数: 297 | 1 There are 2 type of bad sectors
1. logical error
2. physical damaged
The usual way to fix bad sectors is to use low level format.
By doing this,
1. if it is a logical error, it will be corrected
2. if it is a physical error, the s. m. a. r. t function of hard disk will
remap the bad sector to a new place and the hard disk will back to normal
again
But format usually will erase all your data on the disk. Here we are going
to use a local low level format only on the bad sectors

发帖数: 3021 | 4 Back a while ago, i was searching for a low-format tool for linux.
But i didn't find it, most ppl say there is no such thing for linux.....
One of them suggest to write 0 to the whole disk as low-format.
After some googling, it seems there are three level formatting,
1) factory low level formating
Not all sectors on a hard disk are good to use. At the factory they test
this and then map out [called spare sectoring] what is to be used and what
is not to be used.
2) recent low level format defi |

But I heard that once physical damage occurs, the problem will only get
worse over the time. Time to buy a new HD.

fragmentation than windows ntfs/fat32, though i don't know about the read/

发帖数: 723 | 12 the test will be running in background, and after finish, there is no prompt
. You can use smartctl -a and look for the self-test log.
