[TIPS] How To Prevent Bad Sectors In Hard Disks

[KH0UJ]

---

Ants are attracted to sweets and it`s true, and if they explore near your HDD they can smell the fruit based adhesives nga gagamiton sa mga kompanya sa HDD and there goes a dead HDD nya di pa gyud mo warranty ang company basta ant attack... paeta...

Use Naphthalene balls to ensure di kaayo attractive inyong HDD sa insect attacks hehehe, works fine for me

one ball will do then place it in a small zip plastic and put 3-4 needle holes then put it inside the PC casing

dli HDD atkihon sa hulmigas diri sa amo ng akong keyboard gipangkitkit.. hehehehe

btw thanks for the info

How to prevent and Fix:

While running your computer, you may receive error messages suggesting your hard disk might contain bad sectors. The errors are typically flagged as "CRC" or "Cyclic Redundancy Error". Some of your data files are missing, dili na mabasa or corrupted an and then it would takes forever or impossible to access certain files and folders. This may be a cause of bad sector problems. Sectors are pie-sliced divisions of a hard disk. And a bad sector is a sector on the disk which data cannot be written or read due to a physical damage or inconsistencies of parity checking bits on disk. Any data that is written or stored on that area is likely to be lost or corrupted. Data residing on the rest of the disk may be unaffected and the disk is considerably usable if the bad sectors are few.

Bad sectors are mainly due to the magnetic weakening of the domain and mechanical faults. Over time, the magnetic areas of a disk lose its magnetism and hence its inability to retain data. Such bad sectors have the tendency to spread and are usually non-repairable. Mechanical faults include physical shocks to the disk, abrupt power shutdowns and disruptions during read-write operations. Head crash can also cause bad sectors and lead to permanent data loss on the disk. When bad sectors spread, it can result in system instability when important system files are destroyed. Mild corrupted data however can be corrected by most file system utilities.

Ang wala pa ma-ilhi kasagaran sa uban kay ang bad sectors could some times be due to bad parity checking bits written on disk. Most modern disk while storing data will transparently store parity bits together with the data. When the data is read, the parity bits are also retrieved and compared to ensure the data integrity. This goes on without the knowledge of normal user. When the parity bits are corrupted for some reasons, it will result in bad sector errors. In this case, through some proprietary recovery software, ADRC could actually repair the bad sectors without loss of data by correcting or rewriting the corrupted parity bits on disk.

Very often, bad sectors are manifested as a result of failing Read Write head. When the Read Write heads fail to read and interpret the magnetic signals normally, the same kind of bad sectors errors could occur. Frequently, bad sectors are also early signs of disk crash as it deteriorates over time.

Solution to Bad Sector Problem is that, if the disk is still working well, important data should be backed up immediately to avoid further data loss. If the system respond is virtually "hanging" to a standstill and you have valuable data, the best option is to consult a data recovery specialist without doing this yourself.

Commonly, a full format process should be able to "mask" the bad sectors or earmark the bad sectors in file allocation table. One could continue to use the disk while the operating system will take notice of the location of bad sectors and avoid them altogether.

Another common CHKDSK utility provided by Windows Operating System may help to detect and mark for bad sectors. During a surface scan, it attempts to write data to that sector and then read back what it wrote. If the two do not match, the sector is marked as bad as it does not maintain data integrity. The operating system will note the particular sector and avoid writing new data onto that area of disk. After which, the bad sector will be remapped to a special sector on the drive which is reserved for this purpose.

Hope makatabang ni akong tampo sa n u bro. Hanggang sa huli - WIRE "at your service!"

Yes, naa. Pero para sa ako lang dili ko mo gamit ana. Ky ingna ngano kutob ra sa HDD ang kainit kung open imo PC dili jud siya mo transfer sa casing must better para sa ako ang casing nga metal. ug kadtong HDD nga naay pud casing nga guma unya plastic ang screw mao nay hinungdan nga sigi ka ug trabaho mo kalit lang ug hang usayhay imong workstation.

ok, thanks for the info sir.

i will try to follow what you did just to prevent future ant attack. salamat sir, another good info for a noob like me

... nice, 100% like this bro. - Good Point!

Nice Tips ni siya.... gani temp sa akong HD kay naa ra sa 32C-35C bisan wala aircon then naa sad siya support nga HDD Cooler [Deep Cool].

Seperate your system files and your personal data files. Better use SSD for your system files.
