I am trying to clone a harddrive with important data to another harddrive to make sure we can keep those files safe.

Now my old HD is a 500GB 3.5" and the new one is 1TB 3.5". My old HD is plugged directly to my computer and the new HD is plugged with an HD enclosure.

Once I mount the harddrive, I see all the files, no problem. I can copy some files over without a problem. But when I try to copy all files over, its starts to transfer them and then stops after 30 seconds and all files on the old HD are unreadable.

Now, I tried using Clonezilla to clone the old HD to the new HD. It started copying and then after about 30 seconds it said "Could not complete".

When I try and clone the HD by using dd, it give me "I/O errors, 0 bytes transferred".

Any solutions for this? What could be the problem?

Thanks everyone,

Have you just tried copyin the important ones? – cutrightjm Aug 20 '12 at 18:20
We have about 20GB of pictures. 30 seconds after starting to copy them over, the files become unreadable. I need to be able to move them all over to the new HD. – Karl Aug 20 '12 at 18:27
Try using dd_rescue instead. It will skip over bad sectors. – jmreicha Aug 20 '12 at 18:34
Clonezilla also has a "rescue" option. – Darth Android Aug 20 '12 at 19:03
Last I saw, there was just a (sadly, hidden) checkbox labelled -rescue under expert mode:… – Darth Android Aug 21 '12 at 2:15

To answer "What could be the problem?", I suggest a review of permissions. If the permissions are set to limit access or function, it could result in the situation you are describing.

Open "Computer">Right click your source drive (or open to a particular file, if you are pulling over certain files) Click security tab Click Edit Tick Allow for all users Click OK

@Karl Yes That would be for Windows. – Carl B Sep 6 '12 at 1:32
