Acecool You can put the hard-drive in the freezer overnight if there are bearings which are failing - but doing so is DESTRUCTIVE and you'll be able to get some data before it fails completely. This should be used as a LAST RESORT.

If it is the actual PCB, you can sometimes find another drive which has failed but the PCB is good ( MUST BE EXACT ).

First step - make a list of everything you need off the drive in case you are working on a time limit. Copy the most important stuff first, then other stuff afterwards.

If you have access to a hardware clone-machine, sometimes this is the way to go.

If you want to debug what's wrong... There is software called mdisk or something m which should be on hiren's boot disk and others... That will scan every sector of the drive and tell you what is bad. Anything 500ms or over is bad, usually healthy is 150ms or under. Xs mean bad sector...
In some cases there can be a LOT of Xs which causes the drive to fail but you can delete those from the accessibility table to prevent the drive from reading / writing to those sectors, ever... It is a destructive option, but can allow the drive to be used longer.

MHDD, that's it... It is one of the best tools available... But make sure you copy the important data first - because the destructive scan can corrupt some data if sectors are removed which have data on it but are only slow ( you can set what to delete... do the scan first to see where you are at.. but I usually delete 500ms or X if there are not a lot of them - or lower ms sectors such as 250 if the drive isn't full of them )...

Pawelr98 It all depends on what kind of damage you have.
Show the SMART table.

In the end some data may end up corrupted.
However if your HDD is not full of bad sectors then most likely you will be fine.

I prefer full platter scan using MHDD, you get the full image of HDD state.
You can do it after you backup the data as this process takes some time and puts HDD under stress.

Yes, disconnected.....while I decide on what drive to get.

So, copying everything - will result in everything working on the new drive or - if I have some corrupted files or something wrong with any of the files - is there some way to test them or fix them? I thought there was backup software that would try to 'repair' files or does it just try to repair a defective drive? I apologize in advance if any part of this question is kinda dumb. :-/

mo0rd If the drive is still accessible but fails to copy, use TestDisk. I am a technician and this software has been a life saver many times for me.

umeng2002 Just start copying the data somewhere else.

PR-Imagery If the drive is still working and the data is readable, just copy everything over to the new drive.

Steps to backup 'failing' hdd?

My HDD has a bad sector - some SMART tests didn't come back overly positive. I am using Linux - the Windows software isn't really applicable? I was going to use gddrescue but also I think I should buy a NAS HDD although it's not necessary but might be worth getting for copying the data over to it?

I have read through some threads here about hard drive issues including some regarding some hard drives failing but they only gave ideas.

Is there any easy steps one can find?

My HDD has one large partition - 1tb - Hitachi 1TB - 800gb of data - I hope to salvage the drive data and have a backup and hopefully 'fix' the problem on the new drive.
