I have a USB drive used for Time Machine that is failing. Disk Utility says it can't fix it, but says I can copy files from it.

 

I attached a new drive and am using Disk Utility's "Restore" function to clone the new drive from the failing one (both are 1TB drives).

 

Disk Utility says on the screen that it is "copying blocks". Does this mean it's doing an image copy rather than a file-by-file copy? It seems to me an image copy in this case might be bad, because it could cause any file or directory corruption on the old drive to be copied to the new drive.

 

Are my worries justified? Would I be better off just using the Finder to copy files? Are there third-party programs that might be better? (DiskWarrior says it can't fix the old drive because of insufficient memory.)
