[one]

Hi everyone
In the first this error diplayed on laptop:
""windows detected a hard disk problem"
Then I scan laptop hdd with HD Tunes Pro
Its result is here:


and then, I use hdd regenerator for scan and repair!
but in about an hour it founds about 500,000 bad sectors and since It takes a long time to full scan, i didn't continue!
Now what should i do?!
Whats solution?!
I should replacement hdd or i can fix it?!

THANKS

Back Up your data on new hard disk. End of story.
This hard drive can not be repair for further normal use. It is worthless to spend days in self scan and end result to be bad drive again.

..that's if the drive can survive the necessary amount of reading to conduct a backup. I'd send it straight to a data recovery professional if your data is worth more than $500 to you.

It sounds like you can live without your data. If so, then get rid of the drive.

You might try cleaning the HDA contacts, but I doubt that it will solve your problem.

If you need your data, then try to apply the "slow fix":

HDDSuperTool has a "slow fix" script:

You can read all the drive's firmware modules with this script:

Foirst BACKUP ALL THE DATA. Your drive will be gone very soon and will take the data with it !

Buy a new hard drive. If you need to recover the data from your drive you might want to clone it with ddrescue to the new one.

DO NOT USE HDDREGENERATOR on the drive as it will KILL IT for good.

At this point there is no way to reliable fix your drive, unless you have expensive firmware tools and knowledge to Self-Scan the drive, if possible at all, and if the heads/surface are in a bad shape the drive will not pass SS as well to start with.

So your priority should be :

1 - Backup all the data / recover all the data that you can.

2 - Replace the drive.

Thank all
Fortunately data is still available and no problem.
so as a result I replaced the drive.
but generally why HDD regenerator is bad for drive?! and for drives can be restored, what software (for windows or bootable) is good?!
