How to remove Bad Sectors from HD

[madonawills]

I want to remove Bad Sectors from my Hard Disk, How I can ?

Simply stated: You can't.
Even worse: Your HDD is stating to you that its decease is immiment.
Smartcontrol

Code: Select all

sudo smartctl -a /dev/sda

should give you the answer how bad it is.
Back up your data now(!) i.e. even before you run smartcontrol.

It depends. A power outage can cause bad sectors. They can probably be fixed. A deteriorating disk surface or read/write head you may fix some errors now, but they will be back. Noone here could even guess without you posting your SMART numbers. There are lots of disk scanning programs out there from HDD manufacturers, Windows and Linux. You can easily Google search this. Just be aware that these programs are very HDD intensive. They scan the entire disk. If you have a fragile disk to begin with, it may only make it worse. Be prepared with a new drive and save all your important files before you try to fix.

Install "GSmartControl" and/or "Gnome-Disk-Utility (Palimpsest)", Both programs are IMHO the best out there and they work very good in telling you the condition of your disk, been using these programs since Lucid Linx and now on LM Maya!
