A few questions about faulty HDDs and cloning.

The very first thing you’ll want to do is disconnect these drives. Cease enjoying with them. You might be fully rising the chance that the information can be unrecoverable .
now that you just ‘ve achieved that, it ‘s date and time to resolve what to do. I ‘m going to temporary gb5102 on this about ddrescue and testdisk. They’re implausible instruments that I’ve used respective instances. The alone issues I’ve n’t been in a position to get better up to now are flash based mostly reminiscence with fail controllers. You ‘re going to should do some learn to know similar to make use of them, and utilizing a working drive to get a really feel for them is a bang-up concept .
As for sending them to an expert, that ‘s going to be ngoc to the powers that be at your work. They should decide suppose the value is value it. {Of course} this can be a nice {opportunity} to push the awesomeness that’s present in a accompaniment measure .
then about cloning from bigger to smaller ? I might n’t even trouble. Each revolution of a broken drive is a possible for catastrophic failure. And suppose you need to repeat them as a result of the knockoff failed, you ‘re rising the possibilities exponentially.

Revelation of that out of the best way, I ‘ll provide you with a little peak morsel of what I do .
I’ve a system that’s devoted to {recovery}. It ‘s a linux frame. Distro does n’t matter, it ‘s no matter you want. It ‘s received fairly respectable spectacles and plenty of storehouse devoted to recovered knowledge. Your rig does n’t should be a workplace home. One of many largest necessities of knowledge {recovery} is clock. You ca n’t rush it, until you really are n’t attempting to get better the information .
On it I’ve instruments like ddrescue ( and it ‘s graphical person interface ), testdisk, photorec, qemu-kvm, gparted, gsmartcontrol, and another issues for specific {circumstances} that I ‘m not going to look ngoc proper now. I get them from these sources :
testdisk – hypertext switch protocol : //www.cgsecurity.org/wiki/TestDisk
photorec – hypertext switch protocol : //www.cgsecurity.org/wiki/PhotoRec 

ddrescue – hypertext switch protocol : //www.gnu.org/software program/ddrescue/
ddrescue gui – hypertext switch protocol : //launchpad.internet/ddrescue-gui ( runs by the instruction /usr/share/ddrescue-gui/DDRescue-GUI.py )
qemu-kvm is discovered within the repos of my distro

One other nice choice :

spinrite – hypertext switch protocol : //www.grc.com/default.htm 
as soon as I’ve the instruments, I take advantage of physician of divinity to construct an prototype of the drive. then I take advantage of the above instruments to try to get better from the pictures. Until there is no such thing as a different, continuously picture and school class on the pictures. Suppose you kill a picture you continue to have the initial .
This mail is getting approach excessively lengthy. Suppose you need to go this path and would love some steerage, pm me. I ca n’t assure whole {recovery}, {but} I can assist you perceive what to do and what to forward .
