I did a complete backup of a hard drive (1.15 TB) and saved itas an image because my Mac keeps telling me it can't repair theoriginal drive to try backing everything up and reformatting it.This is an external drive. It took 16 hours to create the image.Now that I have reformatted the original drive, I can't get CCC torestore the image. It goes so far and hangs. The drive read/writedrops to zero and it does nothing. Is there anyway to figure outwhat is causing this?

It sounds like you're trying to restore back to the same disk,and that that disk is probably physically failing. If the disk wasstruggling before and it's still struggling now, I suspect you justneed to replace it.

For the sake of thoroughness, I offer some troubleshooting tipsfor diagnosing these kinds of problems here:

I have purchased another external hard drive. However, I amassuming there is an issue with my backup image, as no matter howmany drives I try to restore this imagine onto, it ends up hanging.So far I have been able to get some of my backup restore little bylittle. If I let it go until it hangs, then abort, it allows me totry again and if I tell it not to erase and only replace newer orchanged files it seems to keep building onto it. Very frustratingand slow, but it appears to be working. Is there an option toverify images you create with CCC? I could wish that it hadautomatically verified the imagine when it created it, however, Isuppose it is my fault for assuming the imagine was fine beforeerasing the original copy of the data. I do have a complete onlinebackup with Crashplan, it tells me it would take an estimated 56days to restore my data, or I can have them send me an externaldrive with my data on it for a fee. Either way would get my databack and I can't really put a price on it. I will see what turnsout with the method I am using.

I don't think there's anything wrong with the disk image. Ithink there could be something flaky about the source disk (thatthe disk image resides upon), but I don't see anything wrong withthe disk image itself.

There is a chance that the problems lie on another disk. Thehang reports indicate that CCC was hanging in a couple differentplaces -- when trying to update the list of items to be copied,when trying to add a newly-mounted volume to the source ordestination menu. In all hangs, the hang was ultimately caused bysome volume on the system not responding. Unfortunately, the hanglogs never indicate what file was causing the hang, only what partof my code the hang was occurring in, so I don't know which volumecaused the hang. We can easily rule out every volume except for thesource, destination, and startup disk, though, by simply detachingall volumes from your Mac for the duration of the restore. WhileCCC is running, don't mount any new volumes.

I'm hopeful that the source volume is not the culprit becauseyou had been getting fairly decent performance in a previous(partial?) restore:

03/17 21:08:43 Copying selected files: Time elapsed: 00:50:42.Data copied: 72.81 GB

Hopefully keeping other volumes at bay will allow CCC tocomplete the task.

I am at a loss as to what is causing this. The original sourcedisc that I created the image from is a 3 TB Seagate GoFlex Drive.I started getting notices from OSX saying that the drive could notbe mounted and to try running a repair on the drive. It says itcannot repair and to backup everything ASAP and try reformatting tofix the issue. I purchased a new 3 TB Seagate GoFlex Drive and madean image of the original and saved it on the new drive. As youknow, something keeps causing the restore to hang. I was able toget a complete restore by using the method I mentioned above. Iknow the issue is not caused by CCC. I have tried another backupprogram and it too hangs. I cannot detach any volumes during therestore as the source and destination are both external, and I ofcourse cannot detach the startup disc. I can always resolve thehang by detaching one of the two external drives, so the issue hasto be with one of those I would think. I would surely hope theissue would not be with the brand new drive?!

I would hope as well, but wouldn't discount it at all. Brand newhard drives can have enough failures to be flaky, and I have seenfirst hand an enclosure that functioned on only one interface (USB-- the Firewire interface was slow and the volume wouldspontaneously unmount in the middle of a copy). When you have theopportunity, I offer some tips for isolating these kinds ofproblems here in the documentation:

I seemed to have solved the problem with the hard drivesfreezing up. Apparently installing Seagates Diagnostic tool/Utilitycauses the drive to hang for whatever reason. I have beenexperiencing hangs even while not using CCC and did someinvestigating. After a certain period the drive hangs and you haveto unplug it to make the computer respond again. I uninstalled theseagate software and have not had a problem since. Just a littleFYI to others who may be experiencing the same problem.
