Question

My PC has bad sector of 48 KB. It is maxtor hard drive. I did try to chkdsk and it shows that it has 48 KB in Bad sector. Please any professionals knows how to recover it. I will be thankful to that person whos gives reasonable answer.

Answer 1

Sometimes a scandisk will allow you to recover the sector, but usually the only way to recover the sector is to format the drive, and this doesn't always work. However, since formatting destroys all data, I wouldn't recomend it. 48kb really isn't a big chunk of data, I'd just let it be.

Answer 2

Try following.
1 Step OneDouble-click on My Computer to open the My Computer window.
2 Step TwoSelect the disk that you want to diagnose and repair.
3 Step ThreeChoose Properties from the File menu. You should see the Properties window for the drive that you selected.
4 Step FourChoose the Tools tab.
5 Step FiveClick the Check Now button under Error Checking Status.
6 Step SixDepending on your version of Windows, choose either "Thorough" or "Scan for and Attempt Recovery of Bad Sectors."
7 Step SevenClick on Start.

BUT
Third-party hard-disk utilities do a more thorough job of diagnosis and repair than the software that comes with Windows or Mac OS, but they work much better if you install them before you have a problem.


If you have problems with your hard disk, you must check the logically bad sectors from your Hard Disk.


Logical bad blocks are irregularities on the magnetic part of hdd, formed due to extensive read or write operations, caused by viruses, corruption's in the boot records, sudden voltage surges etc. You need the Disk Repair software who is a hard disk utility that repairs the logically formed bad sectors. Usually the bad sectors spread and corrupt the Track 0 of the hard disk due to which it doesn't get formatted. This problem could also prevent you from installing or copying data because gives error.

Down load the software utilities from Maxtor web site . There free and they have all the utilities you need to repair bad sectors and test for any other abnormalities in the hard drive.Copy them to a 31/2 floppy or cd/dvd disk . Then use it from there( in dos) A low level format is the only assured method of repairing bad sectors ( if it's not a physical defect) , No data will exist on the hard drive after low level formatting twice NOTHING !!! It will take time to LL format a drive of any size , so go take a nap. When its' done the drive will be to factory specs Then quick format using your operating systems' preferance.( ntfs, fat32 , fat 16) Your mbr will be reinstalled. Then install your operating system Do not use a quick format to repair bad sectors . It won't !! Scan disk and check disk will only "bracket" around the bad sector so no programs have write access to it. They don't repair the bad sector

Answer 4

If chkdsk wont recover the bad sector youre not going to get it back. Formatting does nothing to recover bad sectors it just reads and notes them and makes no attempt whatsoever to recover them. That why you run chkdsk before you format the drive if you have bad sectors. I wouldn't worry about recovering one bad 48k sector. What I would be concerned with is more bad sectors popping up. If that happens back up your files because, more than likely, your hard drives going to fail.

Hi,

i think you need to take backup and format your drive using fdisk or extended fdisk or smart fdisk.... and later remove all the partions and then again try formating in corresponding file system , such that bad sectors will surerly removed. this would take some time but still, i dont think we have any popular alternative to suggest.

All the best ,

Answer 7

In my experience once they go bad they stay bad. Worse, they frequently spread like a rash until the drive is toast. I'd start backing up critical data just in case.
