how to fix bad block errors on HDD ?

[HpBaxxter]

I found (2) bad blocks errors, I used MiniTool partition but Windows tool didn't find any thing !!!
I looked up on the net and I found that only software errors could fix.
How do I know if it hardware or software errors ?
and how do fx the software's one ?

how to fix bad block errors on HDD

My fix: backup content asap & buy a new hd.

Block errors indicate a failing hard drive. No software can fix hardware failures -- no matter what the software provider claims.

The sooner you copy the contents onto a new drive, the better your chance of saving its current contents.

I agree with both of the above. You can certainly run the HD makers diagnostics (downloaded from their site) or run chkdsk /r on the drive in an attempt to recover any corrupt data, but this is typically a sign the drive is failing. And typically, once they start to fail, they will continue to fail.

You need to immediately back up any data you don't want to lose.

Use HDD Regenerator for the Errors and TestDisk to get the data off the drive, then replace the HDD.

I had once a customer with the whole Daily-Photo- / Video-Diary of their little daughter on an external HDD, which was not accessible anymore the normal way, but still showed-up in the Computer-Management and I used the above tools to get the stuff off the HDD and only lost 2 (!) Photos.

External Hard-Drive not accessible. 57.985 Bad Sectors recovered. 25.7GB Data recovered.

It took me a whole week (day & night), but it was worth it.
