Re: [Bug-ddrescue] ddrescue

[Dennis Juhler Aagaard]

Hi Tauras,

It is the appropriate time to run dd-rescue.

Before you begin you have to know how dd-rescue are working. 

dd-rescue will save your drive block by block and NOT file by file. This means 
that it will make a copy of all the blocks of your drive to a new destination. 
So if your failed drive is 2TB you will need 2TB or more of free space on the 
new destination.

You are not able to only save those files that you know of, but again need to 
wait for the full rescue has been completed before opening up your image to 
avoid corruption of your image.

I would use a linux live-cd of some sort to make the rescue and not relay on 
making a rescue in Windows. (I dont even know if there is Windows binaries for 
dd-rescue.)
Or use a Mac if you have one. :-)

Read the manual carefully, before making the rescue attempt. :-)

Regards,
Dennis
